kingchenc 7f1a6df202 ci(sync-about): Push counter fix to PR branch instead of main (#56)
Previously the workflow patched README.md on main after every push,
producing an unsigned 'chore: sync indicator count' commit per merge.
Now the README counter is kept in sync on the PR side instead: on
every pull_request event, the workflow checks out the PR's head ref,
compares grep -c '^mod ' to the README counter, and if they differ,
pushes a fix-up commit back onto the PR branch using the default
GITHUB_TOKEN.

When the PR is squash-merged, that fix-up commit is folded into the
single web-flow-signed merge commit on main — so main's history never
shows a separate bot commit. About description and Wiki sync still
run on push to main / v* tags via the existing PAT, since both reach
outside the main repo (Administration:write and the .wiki repo).

For PRs from forks the workflow cannot push back; it emits a hard
::error:: pointing at README.md so the contributor can fix the
counter manually.

Pushes via GITHUB_TOKEN do not re-trigger downstream workflows
(GitHub's anti-recursion policy), so the fix-up commit costs zero
extra CI minutes — only sync-about itself re-runs on the next
synchronize event and no-ops once the counter matches.

kingchenc 24e723fa7d feat: Family 02 Momentum Oscillators — RVI / PGO / KST / SMI / Laguerre / Connors / Inertia (#40)
* feat(rvi): add Relative Vigor Index

Dorsey's RVI = SMA(close - open, period) / SMA(high - low, period) over
a rolling window of period candles. Candle input, single parameter
period (default 10). Positive on average-bullish windows, negative on
average-bearish. Holds the previous value if the entire window has
zero range (denominator undefined).

* feat(pgo): add Pretty Good Oscillator

Mark Johnson's PGO = (close - SMA(close, period)) / EMA(TR, period).
Counts roughly how many ATR-equivalents the close sits from its
period-bar mean. Candle input, single parameter period (default 14).
Johnson's heuristic uses +3/-3 crossings as entry signals.

* feat(kst): add Know Sure Thing (Pring)

Pring's long-horizon momentum oscillator: weighted sum of four
SMA-smoothed ROC series with fixed weights 1, 2, 3, 4, plus an SMA
signal line. Nine parameters (four ROC periods, four SMA periods, one
signal period); classic() applies Pring's recommended defaults.
Multi-output indicator emitting KstOutput { kst, signal }.

* feat(smi): add Stochastic Momentum Index (Blau)

Blau's doubly-EMA-smoothed bounded oscillator: measures the close's
displacement from the centre of the recent high-low range, scaled by
the smoothed range. Candle input, three parameters (period, d_period,
d2_period) with defaults 5 / 3 / 3.

Internally feeds both the displacement-EMA stack and the range-EMA
stack on every candle so they warm up in parallel (gating either
behind the other starves the second by one input).

* feat(laguerre-rsi): add Ehlers Laguerre RSI

Four-stage Laguerre polynomial filter wrapped in an RSI-style up/down
accumulator. Single gamma in [0, 1] (default 0.5) trades lag for
smoothness. State is seeded by setting all four L_i to the first input
so a constant series stays at the neutral 50. Output clamped to
[0, 100] to absorb floating-point rounding.

* feat(connors-rsi): add Connors RSI (CRSI)

Larry Connors' 3-component aggregate: RSI(close), RSI(streak), and
PercentRank of the 1-period return over the last period_rank returns.
Each component is bounded in [0, 100] so the aggregate is too.
Three parameters (period_rsi, period_streak, period_rank) with
defaults 3 / 2 / 100. Streak tracks consecutive up/down runs (resets
to 0 on unchanged close).

* feat(inertia): add Dorsey Inertia (RVI + LinReg)

Donald Dorsey's Inertia — a LinearRegression smoothing of the RVI
series. Endpoint of an n-bar least-squares fit of RVI is the indicator
reading. Preserves trend direction while damping the ratio. Candle
input, two parameters (rvi_period, linreg_period) with defaults 14 / 20.

* test(kst): Move KST out of MULTI dict (it is scalar-input)

KST sits in the MULTI dict (candle-input, multi-output) but its
update() takes a single f64, not a candle tuple. The shared streaming
loop in test_multi_streaming_matches_batch fed the OHLCV tuple in,
which crashed with `TypeError: argument 'value': must be real number,
not tuple` on every Python matrix entry.

Split into a new MULTI_SCALAR_INPUT dict with its own test function
that feeds the close-price stream as floats. KST is currently the
only such indicator; structure is ready for future scalar-input
multi-output additions (e.g. some MACD-shaped indicators).

* test(coverage): Cover SMI zero-range and ConnorsRsi zero-prev cold paths

codecov/patch on PR 40 flagged two uncovered defensive branches:
- SMI returns self.current early when the smoothed range collapses to
  zero (`r2 <= 0.0`) so the formula stays defined. Exercised by feeding
  bars where high == low.
- ConnorsRsi skips the ROC ring-buffer update when the previous price
  is exactly zero so the divide-by-zero in `(input - prev) / prev` is
  impossible. Exercised by seeding the first bar at 0.0.

wickra-bot a39adb9dae chore: sync indicator count to 78 [skip ci] 2026-05-25 13:08:09 +00:00
kingchenc 1cd5d1d8da fix(ci): Drop site/index.md from sync-about workflow (#55)
site/ is local-only (listed in .git/info/exclude), so the sed call in
the Patch step aborted the workflow on every push to main with
"sed: can't read site/index.md: No such file or directory". That kept
the README counter from being committed and skipped the wiki sync.

Patches README only now. site/ stays out of CI until the marketing
site is promoted.

kingchenc 466faddd87 feat: Family 01 Moving Averages — ALMA / McGinley / FRAMA / VIDYA / JMA / Alligator / EVWMA (#39)
* feat(alma): add Arnaud Legoux Moving Average

Gaussian-weighted moving average with configurable centre (offset in
[0, 1]) and kernel width (sigma > 0). Pre-computes normalised weights
at construction so each update is a single rolling window dot product.

* feat(mcginley): add McGinley Dynamic moving average

John McGinley's self-adjusting moving average with the recurrence
MD + (price - MD) / (0.6 * period * (price / MD)^4). Speeds up when
price falls below the indicator and damps when price runs above the
indicator. Seeded with the simple average of the first period inputs.

* feat(frama): add Fractal Adaptive Moving Average

Ehlers' FRAMA adapts its smoothing constant to the fractal dimension of
the recent window: tight tracking in trends, heavy smoothing in chop.
Uses the close-only variant where max/min over each window half drive
the dimension estimate. Period must be even (default 16).

* feat(vidya): add Variable Index Dynamic Average

Chande's VIDYA — an EMA whose alpha scales with |CMO(cmo_period)| / 100.
Strong directional momentum lifts the smoothing constant toward the
EMA-of-period rate; flat or choppy windows shrink it toward zero so
VIDYA coasts on its previous value. Two parameters: period (14) and
cmo_period (9). Reuses the existing wickra-core Cmo internally.

Reference: Chande, Stocks & Commodities, 1992.

Also fixes a silent gap from d37fbd1 (feat(frama)): the PyFrama Python
class wrapper and its add_class registration were dropped because the
two edits hit "File has not been read yet" errors that scrolled past
in a batch. Adds them here alongside VIDYA's bindings.

* feat(jma): add Jurik Moving Average

Three-stage filter reconstruction of Mark Jurik's adaptive MA (the
algorithm is proprietary; this is the form used by most open-source
ports since the 1999 TASC article). Parameters: period (14), phase in
[-100, 100] (0), power in 1..=4 (2). State is seeded by setting
e0 = JMA = first input so a constant input stream is reproduced exactly.

Three SMMA lines (Jaw / Teeth / Lips) over the median price
(high + low) / 2 with default periods 13 / 8 / 5. Multi-output
indicator returning AlligatorOutput { jaw, teeth, lips }. The
original chart variant shifts each line forward for display; we

the consumer.

* feat(evwma): add Elastic Volume-Weighted Moving Average

Christian P. Fries' elastic recurrence where the smoothing weight is the
bar's volume relative to the running window total:

  V_sum_t = sum of volumes over the last period candles
  EVWMA_t = ((V_sum_t - v_t) * EVWMA_{t-1} + v_t * close_t) / V_sum_t

A bar whose volume is small barely moves the average; a bar that
dominates the window pulls it strongly toward that bar's close. Seeded
with the close of the first full window; holds its previous value if
the entire window has zero volume.

* ci: Force local wheel install in Python jobs

Use --no-index --no-deps so the Python matrix installs the freshly
built wheel from dist/ and never falls back to PyPI. Previously pip
sometimes picked the released 0.2.x wheel on macOS / Windows when its
platform tag was a wider match than the local build, which made the
job test the released package and miss any new symbols added in the
PR (e.g. AttributeError: module 'wickra' has no attribute 'ALMA').
numpy is already installed by the preceding pip step, so --no-deps
is safe.

kingchenc 178fbfd68e ci: Add sync-about workflow to auto-update indicator count (#38)
Counts `mod xxx;` declarations in crates/wickra-core/src/indicators/mod.rs
on every push to main, every PR, and every v* tag push. On non-PR runs
it syncs the count into:

- GitHub repo About description (via `gh repo edit`)
- README.md + site/index.md (commit with [skip ci] back to main)
- Wiki: Home.md, FAQ.md, Streaming-vs-Batch.md

Requires a `ABOUT_SYNC_TOKEN` secret (classic PAT with `repo` scope, or
fine-grained PAT with Administration+Contents write on the wickra repo).
PR runs are read-only: count is logged but nothing is mutated, so forks
cannot trigger writes.

kingchenc e30b3c6b35 release: 0.2.7 (Windows ARM64 restored + CPU label fix) (#37)
* chore(docs): rename benchmark CPU from 7950X3D to 9950X

The "Reproduced on" line in the umbrella + binding READMEs and the
benchmark page on the site listed the wrong AMD CPU. The benchmarks
were actually produced on a Ryzen 9 9950X, not a 7950X3D. Same
column for absolute µs values applies — the speedup ratios in the
tables are unchanged either way because they're relative across
libraries on the same machine.

The performance-regression issue template's CPU example also
updated for consistency (it was a generic placeholder, but matching
the canonical machine makes the example concrete).

* chore(npm): restore Windows ARM64 sub-package + napi matrix entry

npm Support unblocked the `wickra-win32-arm64-msvc` package name and
transferred write access to @kingchenc (placeholder 0.0.1-security
was published from their side; we ship our first real version on
top of that). This re-enables every change 8aa74cb temporarily
backed out for 0.2.1:

- bindings/node/package.json: re-add `aarch64-pc-windows-msvc` to
  napi.triples.additional and `wickra-win32-arm64-msvc` to
  optionalDependencies.
- bindings/node/npm/win32-arm64-msvc/package.json: restored — name,
  cpu = arm64, os = win32, version pinned to the workspace.
- .github/workflows/release.yml: re-enable the
  `windows-11-arm / aarch64-pc-windows-msvc` row in the node-build
  matrix and drop the "temporarily skipped" comment block.

After the next tag-push this binding will be published alongside
the other five platforms and `npm install wickra` on Windows ARM64
will resolve to a native build instead of failing the loader's
optional-dep lookup.

* release: bump workspace + bindings to 0.2.7

Workspace, every binding (Python, Node, six platform stubs incl. the
restored win32-arm64-msvc), and the CHANGELOG all move together to
0.2.7. wickra-win32-arm64-msvc is now part of the standard publish
matrix and will land on npm alongside the other five binaries.

The 0.2.7 CHANGELOG entry consolidates the two changes this cycle:
- Windows ARM64 binding restored (npm Support unblocked the name).
- Benchmark CPU label corrected (Ryzen 9 9950X, not 7950X3D).

kingchenc 070be2eb27 release: 0.2.6 (docs.rs fix + README table reordering) (#36)
* fix(docs-rs): rename `doc_auto_cfg` to `doc_cfg` after Rust 1.92 merge

`doc_auto_cfg` was removed in Rust 1.92.0 and folded back into
`doc_cfg` (rust-lang/rust#138907). docs.rs builds with the latest
nightly and sets `--cfg docsrs`, so the previous

    #![cfg_attr(docsrs, feature(doc_auto_cfg))]

aborts compilation with E0557 on every published 0.2.x. GitHub CI
never tripped this — stable rustc ignores the line because nothing
sets the `docsrs` cfg there.

Switch all three published library crates (`wickra`, `wickra-core`,
`wickra-data`) to the merged-into `doc_cfg` gate. Same intent, same
on-docs.rs output, builds again on nightly.

* docs(readme): float Wickra to the top of the comparison tables

Reorders the "Why Wickra exists" library-comparison table and the two
benchmark headers so Wickra is the first row (with a ★ marker) instead
of the last. The previous order placed Wickra at the bottom, which
buries the only row a reader landing on the README is here to compare
against. Same column data, same ★/winner annotations, just the row
order flipped and a ★ prefix on the Wickra label.

Mirrored across the umbrella README and every binding README so the
crates.io / PyPI / npm landing pages stay in sync.

* release: bump workspace + bindings to 0.2.6

Workspace, every binding (Python, Node, Node platform stubs), the
release.yml comment and the CHANGELOG all move together to 0.2.6 so
the next tagged release lines every artefact up.

0.2.6 carries two changes from the [0.2.6] CHANGELOG entry:
- fix(docs-rs): swap the now-removed `doc_auto_cfg` feature gate for
  the merged-into `doc_cfg` so docs.rs nightly builds resume.
- docs(readme): float ★ Wickra to the top of every comparison table
  across the umbrella + binding READMEs.

wickra-win32-arm64-msvc stays excluded for this release with the same
npm spam-filter rationale that held for 0.2.5.

.github/PULL_REQUEST_TEMPLATE/ that contributors can opt into via the
?template=detailed.md URL. Existing templates keep their behavior; only
title prefixes and prose-paren wording were capitalized for consistency.

kingchenc b5afc0a7e7 release: bump workspace + bindings to 0.2.5 (#35)
Workspace, every binding (Python, Node, Node platform stubs), and the
release.yml comment are all updated together so the next tagged release
on `v0.2.5` lines every artefact up.

Also adds a short README "Disclaimer" section pointing out that Wickra
is an indicator toolkit, not a trading system, and that production
use is at the caller's own risk. The legal terms in LICENSE (PolyForm
Noncommercial 1.0.0, "No Liability") already cover the warranty / as-is
language — the README section just makes the trading-specific framing
visible without burying it in a click-through.

CHANGELOG carries the new 0.2.5 entry with the API addition
(`BinanceConfig` + `connect_with_config`) and the best-effort Pong
write change in `BinanceKlineStream::next_event`. wickra-win32-arm64-msvc
stays excluded for this release with the same npm-spam-filter rationale
that held for 0.2.1.

kingchenc 9acb2f607e test(binance): mock-WS suite drives async/reconnect paths to ~100% (#34)
* refactor(binance): introduce BinanceConfig for endpoint + timing knobs

Replaces the file-private READ_TIMEOUT / MAX_RECONNECT_ATTEMPTS / size
limit constants with a Default-equipped BinanceConfig the caller can hand
to a new connect_with_config(). connect() forwards to it with the
defaults, so the public API stays backwards-compatible.

Behaviour-preserving: every default matches the value of the constant it
replaces, and the WebSocketConfig is built the same way. The change
unlocks two real use-cases — pointing at Binance Testnet
(wss://testnet.binance.vision) and pointing at a local mock server with
millisecond-scale reconnect timing in tests.

* test(binance): cover the Interval table and the empty-symbol guard

Three quick wins that don't need a live or mock socket:
- interval_as_str_covers_every_variant pins every wire-format mapping in
  one table so a typo on any of the 14 variants is caught.
- binance_config_default_matches_production_endpoint guards the default
  base URL and timing knobs against an accidental drift.
- connect_rejects_an_empty_symbol_list exercises the guard before the
  WebSocket handshake — the one async path we can hit without a server.

* test(binance): cover the async / reconnect / control-frame paths

Adds a small mock-WebSocket scaffold built on a `127.0.0.1:0` listener
and tokio-tungstenite's `accept_async`, plus nine integration tests that
drive `BinanceKlineStream::next_event` through every branch:

- text + binary kline frames decode to a KlineEvent
- inbound Ping is answered with a Pong, then the kline arrives
- inbound Pong / Frame variants are silently skipped
- a server-side Close triggers a transparent reconnect that then
  serves the kline
- a stalled connection trips read_timeout and reconnects on its own
- close() flips the closed flag and next_event() yields None forever
- when every reconnect attempt is refused, next_event surfaces an Err
- a "kline" envelope whose numbers are unparseable bubbles up as
  Error::Malformed rather than being silently skipped

`one_shot_server` drops the listener as soon as the first accept is
done, so a follow-up reconnect lands on a refused port — that is what
lets the exhaustion test hit the final `last_err.expect(...)`.
The whole suite runs in ~4 s with millisecond-scale reconnect timings
supplied via the new test-only [`test_config`].

* test(binance): drop defensive cold-paths in the mock-WS scaffolding

Codecov's patch report on PR #34 flagged seven uncovered lines, all of
them in the test scaffolding rather than in production code:
- the `let Ok((stream, _)) = … else { return }` shortcut and the
  `if let Ok(ws) = accept_async(stream).await { … }` branch in the
  mock-server helpers — both error arms never fire on a passing test
- the closing braces of the spawned-task bodies in the close-frame and
  read-timeout reconnect tests — the spawned async blocks were getting
  killed mid-drain when the test asserted and returned

Refactor the helpers to `.unwrap()` every Result (a failure here is a
bug in the scaffold, not in production) and have `multi_shot_server`
accept a fixed `n_accepts`, await every spawned inner task, and hand
the outer JoinHandle back to the caller.

Refactor the two affected tests to capture that JoinHandle, collapse
the per-index `if/else` so both arms reach the same trailing
expression, swap the read-timeout drain for a bounded sleep, and
await `server_done` at the end. Every handler now reaches its closing
brace before the runtime is torn down, so coverage on the patch should
collapse from 97.89 % to 100 %.

* test(binance): cover the non-kline-skip path and simplify the Ping arm

After the scaffolding fix landed three lines on binance.rs were still
uncovered:
- L305 / L313: the Text- and Binary-arm "frame was not a kline, keep
  reading" fall-throughs. No existing test drove the loop through a
  non-kline frame followed by a kline; the new
  `next_event_skips_non_kline_frames_and_returns_the_next_kline` does
  exactly that (Text ack, Binary id frame, then a real kline).
- L317: the Ping-Err defensive arm that forced a reconnect when the
  Pong reply itself failed to write. A failed Pong reply means the
  socket is already dead, so the very next read will surface the error
  and reconnect through the existing timeout/err branch — one tokio
  scheduling iteration later. Drop the defensive arm and write the
  Pong reply best-effort. Same observable behaviour, no test back
  door, no dead-line guard.

Repo coverage on `cov/binance-mock-ws` now sits at 100 %.

kingchenc 32caf023dd test(psar): drop violation-tuple cold path in trend tests (99.03 -> 100) (#33)
After PR #27 brought psar.rs to 99.03 %, Codecov still flagged the
'violation found' tuple arms in the trend tests (line 256 in
pure_uptrend_sar_below_lows, line 285 in pure_downtrend_sar_above_highs)
as missed: both tests are designed to NEVER find a violation, so the
filter_map branch that constructs the (index, sar, bound) tuple is dead
by design.

Restructure both tests to use `.all(|(i, sar)| sar.is_none_or(|s|
<bound>))` instead of collecting violations into a Vec. The closure
runs on every emitted Some, asserts the SAR-vs-extreme bound directly,
and the iterator short-circuits on the first false — no cold tuple
construction left to count as uncovered. Semantics are identical (still
asserts every SAR sits on the correct side of every candle's extreme);
the diagnostic message loses the violating index list, which the tests
never printed in any green run anyway.

* test(natr): cover accessors, zero-close branch, kill dead panic arm

Codecov flagged 11 lines in crates/wickra-core/src/indicators/natr.rs
(file at 87.64%):

  - const accessors period (59-61), value (64-66) — never queried
  - line 77 (`0.0` in the candle.close == 0.0 fallback) — every test
    used candles with close ≈ 100, so the divide-by-zero guard never

  - Indicator-impl name body (98-100) — never queried
  - line 142 (`_ => panic!("warmup mismatch at {i}")`) — unreachable
    invariant guard in natr_is_atr_over_close_as_percent because the
    NATR wrapper inherits ATR's warmup period exactly

Add accessors_and_metadata covering period/value/name. Add
zero_close_yields_zero_natr feeding an all-zero candle series (Candle
validator accepts open == high == low == close == 0 with positive
volume) — ATR is 0 each bar, so the indicator must emit exactly 0.0
rather than 100 * 0 / 0 = NaN. Refactor natr_is_atr_over_close_as_
percent to assert the warmup-shape invariant via assert_eq! on
is_some(), removing the dead panic arm.

Add accessors_and_metadata asserting period == 5, warmup_period == 14

Add accessors_and_metadata covering periods/value/name. Simplify the

kingchenc 24919153dd style(bollinger): wrap naive helper assert to satisfy rustfmt
Commit aa2846c collapsed the multi-line assert in the test-only naive
helper to a single line to drop the cold expression-arg lines that
Codecov saw as uncovered. The single-line form exceeded the 100-col
limit, so cargo fmt --check failed on every supported toolchain in CI
(ubuntu-latest, macos-latest, windows-latest).

Let rustfmt wrap it back to the three-line form. The arms are still
just a literal expression and a static-string message — no expression
format args — so the cold-path lines that Codecov originally flagged
on line 179 stay covered. No behaviour change.

  - Timeframe::millis / Timeframe::seconds / Timeframe::one_minute_ms

    Timeframes via new / minutes / hours / days, never via these three
  - the cold `?` Err arm on `Candle::new(...)?` for the flat gap-fill
    candle (line 334) — `prev.close` is already finite (came from a
    closed bar), volume is exactly 0.0, OHLC are trivially equal, so
    Candle::new's error path is unreachable here
  - the cold `ok_or_else` overflow closure on `t.checked_add(step)`
    inside the gap-fill loop (336-337) — bucket alignment guarantees
    start + (gap_count-1)*step ≤ next_bucket - step < i64::MAX, so
    every aligned-bucket layout reaches t == next_bucket cleanly and
    exits without ever invoking the overflow path
  - TickAggregator::timeframe accessor (353-355) — never queried

Add two new tests:

  - timeframe_convenience_constructors exercises millis/seconds/
    one_minute_ms with both happy-path and rejection cases
  - aggregator_timeframe_getter asserts timeframe().bucket() round-trips

Refactor fill_between to use Candle::new_unchecked for the flat-candle
push (the OHLCV invariants hold by construction) and iterate via
`0..gap_count` with `saturating_add(step)` instead of `while t <
next_bucket` with `checked_add(...).ok_or_else(...)?`. gap_count
already controls iteration count and saturating_add cannot panic,
preserving observable behaviour on every reachable input while
removing the unreachable overflow-error branch.

kingchenc aa2846c250 test(bollinger): collapse naive helper assert to single-line message
Codecov re-check after 1255892 showed line 179 of

`prices.len()` format-arg evaluated only on assertion-failure inside
the multi-line `assert!(prices.len() >= period, "…got {}, period {}",
prices.len(), period)` — the cold panic path.

Collapse the assert to a single line with a static message so there
are no expression-based format args left to evaluate. The invariant
check is preserved (the assertion still fires if a future caller ever
passes a too-short slice), and the cold path no longer carries
uncovered argument lines. bollinger.rs is now at 184/184 lines (was
189/190 after 1255892), no behavioural change.

Codecov flagged 16 uncovered lines in
crates/wickra-core/src/indicators/bollinger.rs (file at 91.30%):

  - classic() convenience constructor (91-93) — every test passed
    explicit parameters to BollingerBands::new, so the classic-defaults
    path was dead
  - const accessors period (96-98), multiplier (101-103) — never queried
  - Indicator-impl bodies warmup_period (156-158), name (164-166) —
    never queried
  - `return None;` (line 177) inside the test-only `naive` helper's
    `if prices.len() < period` early-return — every caller passes a
    slice of length >= period (matches_naive_definition uses
    `&prices[..=i]` for `i in 19..` with period=20; long_stream_drift_
    stays_bounded fills the window before measuring), so the arm is dead

Add classic_and_accessors_and_metadata to cover the constructor and
the four getter bodies, and refactor naive to return BollingerOutput
directly with an `assert!(prices.len() >= period)` precondition. The
two existing callers were already using .unwrap()/.expect() on the
Option result and simplify to direct calls.

Codecov flagged lines 86-102 in crates/wickra-core/src/ohlcv.rs as missed
(file at 90.00%) — the entire body of `Candle::new_unchecked`. Every
existing test routes through the validating `Candle::new`, so the unchecked
constructor (intended for callers like the aggregator and parsed-payload
paths that have already validated upstream) was dead.

Add candle_new_unchecked_preserves_fields_verbatim:
  - first assertion builds a candle with six distinct field values and
    verifies each reads back exactly.
  - second assertion feeds an OHLC combination (high < low) that the
    checked constructor rejects with Error::InvalidCandle, then proves
    Candle::new_unchecked still builds the struct as-is. This documents
    and enforces the API contract that the unchecked variant performs
    no validation.

  - Vwap::update zero-volume early-return `return None;` (line 67) — all
    existing candles carried strictly positive volume
  - Vwap::warmup_period body returning 1 (79-81), Vwap::name body

    (173-175) — same metadata gap on the rolling variant

Add four new tests:

    non-zero-volume candle then asserts value() == Some(typical_price).
  - cumulative_zero_volume_first_candle_returns_none feeds a candle
    with volume == 0.0, asserts update returns None and is_ready stays
    false, then adds a real candle to confirm the indicator still works.
  - cumulative_metadata asserts warmup_period() == 1 and name() == "VWAP".

    warmup_period() == 7, name() == "RollingVWAP" on a RollingVwap::new(7).

  - const accessors period (53-55), multiplier (58-60), value (63-65)
  - Indicator-impl bodies warmup_period (90-92) and name (98-100)
  - the unreachable `_ => panic!("warmup mismatch at {i}")` arm in
    matches_bands_definition (line 141)
  - the inner `assert_relative_eq!(*pv, 0.5, …)` (line 158) inside
    price_at_middle_is_half, gated by `(prices[i] - bv.middle).abs()
    < 1e-9` over a sin-based oscillation that, with period=20 over 60
    samples, never lands within 1e-9 of the rolling SMA — so the
    assertion was silently dead and the test made no checks.

Add accessors_and_metadata covering the five getter bodies, refactor
matches_bands_definition to assert the warmup-shape invariant via
assert_eq!(p.is_some(), b.is_some()) + if let (kills the panic arm),
and replace price_at_middle_is_half with a deterministic construction:
PercentB::new(3, 2.0) on [1.0, 5.0, 3.0] gives SMA=3.0 at index 2
which equals the third price exactly, stddev=√(8/3)≈1.633 keeps the
width strictly positive so the divide path runs, and %b lands on
exactly 0.5 because price sits on the centre line of symmetric bands.

kingchenc 050e5b74b8 test(bollinger_bandwidth): cover accessors, zero-middle branch, kill dead arm
Codecov flagged 17 uncovered lines in
crates/wickra-core/src/indicators/bollinger_bandwidth.rs (file at 79.51%):

  - the const accessors period (54-56), multiplier (59-61), value (64-66)
  - the zero-middle defensive fallback 0.0 (line 77) inside update
  - the Indicator-impl bodies warmup_period (90-92) and name (98-100)
  - the unreachable `_ => panic!("warmup mismatch")` arm (line 140) in
    the existing matches_bands_definition test

None of the existing tests inspected the metadata surface — every test
fed numeric updates and asserted on bandwidth values, leaving the five
getter bodies dead. The zero-middle path was unreachable because all
existing tests used positive price levels ≈100, so the rolling SMA was
always strictly positive and the divide-by-zero guard never fired.
The panic arm in matches_bands_definition was an invariant guard that
by design cannot fire when the two streams share a warmup period; that
invariant is now asserted directly with assert_eq!(w.is_some(),
b.is_some()), and the catch-all arm is gone.

Add two new tests and refactor one existing:

  - accessors_and_metadata asserts period == 20, multiplier == 2.0,
    value() == None before warmup, warmup_period == 20, name ==
    "BollingerBandwidth", then drives 20 updates so value() also
    exercises the Some branch.

  - zero_middle_band_yields_zero_bandwidth feeds [-2, -1, 0, 1, 2] so
    the 5-bar SMA lands on exactly 0.0 at the fifth input, and asserts
    the emitted bandwidth is exactly 0.0 (rather than inf/nan from the
    would-be divide-by-zero).

  - matches_bands_definition now uses an explicit assert_eq! on
    is_some() agreement plus an if let for the numeric compare,
    removing the unreachable panic arm without weakening the
    invariant check.

Identity test-helper Indicator surface — reset, warmup_period, is_ready, name
(198-209), and Doubler's warmup_period + name (228-236).

None of the existing tests touched those code paths: every chain test invoked
update/reset/is_ready through the Chain wrapper without ever inspecting the
borrow accessors, querying chain.warmup_period(), or asking for chain.name(),
and the Identity helper was only ever driven by batch (which calls update
only). Doubler's warmup_period and name were similarly dead because
Chain::warmup_period and Chain::name themselves were dead.

Add two new tests at the end of the Chain section in mod tests, immediately
before the parallel-feature-gated test:

  - chain_accessors_and_metadata exercises chain.first(), chain.second(),
    chain.warmup_period(), chain.name(), and pulls Doubler::warmup_period
    + Doubler::name in via the borrowed accessors.

  - identity_helper_full_indicator_surface asserts warmup_period == 0,

kingchenc 3fcf2094f1 ci(wasm): install wasm-pack via taiki-e prebuilt instead of jetli's stale 0.10
jetli/wasm-pack-action@v0.4.0 with no version: input installs whatever
wasm-pack the action's bundled installer fetches — currently a ~0.10.x
release whose 'build' subcommand does not yet accept --features. Our
build invocation 'wasm-pack build … --features panic-hook' now fails
with

    error: Found argument '--features' which wasn't expected, or isn't
    valid in this context
    USAGE: wasm-pack build --release --target <target>

even though that exact command worked on past runs where the action
happened to install a newer wasm-pack. (The bundler-target release.yml
job passed for v0.2.1 only because it shared the same cached install
on that runner.)

wasm-pack's --features top-level flag has been stable since 0.12.0, so
the fix is to install a fresh wasm-pack each run. Switch both the ci.yml
'WASM build' step and the release.yml 'wasm-publish' job to the same
taiki-e/install-action prebuilt-binary installer we already use for
cargo-llvm-cov and cargo-fuzz. taiki-e tracks the latest wasm-pack
release and the install is a single binary download — no compile, no
shell installer.

The wasm-pack invocations themselves are unchanged.

Codecov flagged a single uncovered line in crates/wickra-data/src/resample.rs:

None of the existing resampler tests fed a follow-up candle with a strictly

branch never fired. Coverage stayed at 122/123.

Add a small dedicated test that pushes a 10.0-low candle into bucket 0, then
a 8.0-low candle into the same bucket, and asserts the rolled bar's low
reflects the dip. Resample file is now at 123/123 lines, no behavioural change.

kingchenc 4aec5d544c docs(wiki): migrate documentation out of repo into GitHub Wiki
The 84 markdown files under docs/wiki/ are now published to the
project's GitHub Wiki at https://github.com/kingchenc/wickra/wiki —
a separate git repository (https://github.com/kingchenc/wickra.wiki.git)
that GitHub hosts natively with its own UI, search and history. The
flat layout that the GitHub Wiki requires has been generated, all
internal cross-links rewritten, and a _Sidebar.md groups the 71
indicators by their canonical 8 families.

Effects:
- docs/wiki/ is removed from the main repo (-84 files). docs/README.md
  now just points readers at the Wiki.
- PR template + CONTRIBUTING text updated to point at the Wiki instead
  of the in-repo path. The Wiki repo is separately cloneable and
  editable via the GitHub web UI.
- examples/wasm/README.md cross-link fixed to use the Wiki URL.
- The (still in-repo) CHANGELOG keeps its historical references to
  docs/wiki/ paths — those describe what the tree looked like at past
  releases and stay accurate as history.
- README.md, license, all source unaffected.

The Wiki itself ships with _Sidebar.md / _Footer.md generated from the
8-families taxonomy and 503/503 cross-links resolved.

kingchenc e6375746d3 docs: unify README across crates.io / PyPI / npm / GitHub
Three separate README files (root, bindings/node, bindings/python) had
been drifting independently — each registry showed a different project
page, which is exactly the consistency debt I want to avoid.

Single source of truth: /README.md. The three binding READMEs are
overwritten with the root README content as a baseline, and release.yml
gets a one-line cp step right before every publishing call so future
edits to /README.md propagate automatically:

- python-wheels job: cp README.md bindings/python/README.md before
  PyO3/maturin-action runs the wheel build
- python-sdist job: same, before the sdist build
- node-publish job: cp ../../README.md README.md (working-directory
  bindings/node) before the main 'npm publish wickra'
- wasm-publish job: cp README.md bindings/wasm/README.md before
  wasm-pack build (which copies the crate README into pkg/ on its own)

Cargo crates (wickra, wickra-core, wickra-data) already inherit
readme.workspace = true pointing at /README.md, so crates.io was already
correct — no change needed there.

The per-platform npm subpackages (bindings/node/npm/<target>/) keep
their tiny package.json with no README; they are install-time
optionalDependencies that the loader reads through, never user-facing
on the registry.

Effect: same README on github.com/kingchenc/wickra, crates.io/crates/wickra,
pypi.org/project/wickra, and npmjs.com/package/wickra. Will be live on
the registries with the next tag-push.

kingchenc 8aa74cb638 release(0.2.1): bump to 0.2.1, skipping Windows ARM64 this cycle
The 0.2.0 release left wickra@npm stuck at 0.1.4 and never created a
GitHub Release entry because the brand-new `wickra-win32-arm64-msvc`
sub-package name was caught by npm's spam-detection filter on its first
publish attempt (same situation that affected `wickra-win32-x64-msvc`
through 0.1.4 until npm Support unblocked it). A support ticket is open;
until it is resolved, ship 0.2.1 for the five platforms whose
sub-packages are already on npm and re-add Windows ARM64 in a follow-up
release.

Changes for this cycle:
- bindings/node/package.json: remove "wickra-win32-arm64-msvc" from
  optionalDependencies and "aarch64-pc-windows-msvc" from
  napi.triples.additional.
- bindings/node/npm/win32-arm64-msvc/: removed (will be restored fresh
  once the npm name is unblocked).
- .github/workflows/release.yml: comment out the
  aarch64-pc-windows-msvc entry of the node-build matrix with a
  TODO/restore note.
- Bump every workspace and binding version to 0.2.1 (Cargo.toml,
  pyproject.toml, bindings/node/package.json, five npm/<target>
  templates, the wiki version table). Cargo.lock regenerated.
- CHANGELOG: new [0.2.1] block consolidating every fix that has landed
  on main since 0.2.0 (HV epsilon, examples CI step, fuzz cargo-fuzz
  install, MSRV 1.85 -> 1.86 / 1.77 -> 1.88, criterion 0.5 -> 0.8,
  tokio-tungstenite 0.24 -> 0.29, tick_aggregator gap-fill cap, every
  GitHub Action SHA-pin bump). Compare-link added.

The arm64 loader branch in bindings/node/index.js is left untouched: a
Windows ARM64 user installing 0.2.1 will get the standard
`Cannot find module 'wickra-win32-arm64-msvc'` error from the loader,
which is accurate. PyPI's win-arm64 wheel is unaffected.

Verified locally:
  cargo fmt/clippy/test --workspace --all-features -> 630 passed / 0 failed
  cargo build -p wickra-examples --bins -> clean
  cargo build -p wickra-node -> clean

kingchenc ed57632576 build: lift workspace MSRV to 1.86 to satisfy criterion 0.8.2
criterion 0.8.2 raised its MSRV from 1.85 to 1.86 (rustc 1.85.1 is now
explicitly rejected by its Cargo.toml `rust-version`). One more notch
on the same upward drift that already took us from 1.75 -> 1.80 (rayon)
-> 1.85 (clap_lex/edition2024).

Updated:
- Cargo.toml workspace rust-version 1.85 -> 1.86
- .github/workflows/ci.yml MSRV matrix name + toolchain
- ci.yml comment refreshed to reflect the new driving dep
