Close the "multi-timeframe" cell of the cross-language matrix for WASM.
* examples/wasm/multi_timeframe.html — fetches the bundled 1-minute
BTCUSDT CSV (or any 1-minute OHLCV CSV), rolls it up in-page to 5m,
15m, 1h, 4h and 1d buckets, and prints RSI(14), MACD(12,26,9)
histogram and ADX(14) per timeframe via the WebAssembly bindings.
Same inline-bucket aggregation as the Node sibling, same indicator
set as the Python and Rust siblings — the Rust version uses
`wickra-data::Resampler` directly which is currently a Rust-only API.
The render is a single table (one row per timeframe) so the cross-
language outputs sit side-by-side cleanly. The inline module script
syntax-checks cleanly under `node --check`.
Close the "live trading" cell of the cross-language matrix for WASM.
* examples/wasm/live_trading.html — opens a native browser `WebSocket`
to Binance's public kline stream, feeds every close through RSI(14),
MACD(12,26,9) and Bollinger(20, 2.0) via the WebAssembly bindings, and
flags BUY/SELL candidates when all three indicators agree. Mirrors
the Node and Python live-trading examples in indicator set, signal
logic and symbol/interval validation — the symbol is checked against
`^[A-Za-z0-9]+$` before being spliced into the stream URL, the
interval against the public-API allow-list.
The UI shows live close / RSI / MACD-histogram / Bollinger-band cards,
plus a scrolling log of the last 200 ticks with signal rows highlighted.
Browser-native `WebSocket` means no library dependency. Build the WASM
module once (`wasm-pack build bindings/wasm --target web --release
--features panic-hook`), serve the repository root and open
`examples/wasm/live_trading.html`.
The WASM example set had only `index.html` (the streaming canvas demo);
the "backtest" cell of the cross-language matrix was empty. Close it.
* examples/wasm/backtest.html — loads the wasm-pack `--target web`
bundle, fetches an OHLCV CSV from the same `examples/data/` directory
the other languages use (default: `btcusdt-1d.csv`), parses it
in-page and streams every candle through SMA, EMA, RSI, MACD,
Bollinger, ATR, ADX and OBV via the WebAssembly bindings. Renders a
summary table with mean / min / max / last per series — mirrors the
Rust, Python and Node backtest examples both in indicator set and in
output shape.
Build the WASM module once (`wasm-pack build bindings/wasm --target web
--release --features panic-hook`), then serve the repository root and
open `examples/wasm/backtest.html`. The inline module script
syntax-checks cleanly under `node --check` on the extracted body.
Finish the per-language `examples/<lang>/` restructure by relocating the
WASM browser demo from bindings/wasm/examples/ to examples/wasm/.
* `examples/wasm/index.html` is the moved file; its WASM module import
becomes `../../bindings/wasm/pkg/wickra_wasm.js` so the demo still loads
the wasm-pack output without copying it.
* bindings/wasm/README.md, Quickstart-WASM.md, examples/README.md and the
root README "Languages" + project-layout block all point at the new
path. The serve command in the docs now says "serve the repository root
and open examples/wasm/index.html".
`bindings/wasm/examples/` is empty after the move; the now-empty
directory is removed.
