MT5 Multi-Timeframe Candlestick Pattern Scanner & Backtester v9

A comprehensive tool to scan M5, M15, H1, H4, D1 charts for classical candlestick patterns, backtest their performance with realistic entry/exit simulation, and run a live scanner that scores and alerts when a new pattern appears.

---

Features

• 50+ patterns: classic single-candle (Doji, Dragonfly Doji, Gravestone Doji, Hammer, Shooting Star, Marubozu, Belt Hold, Inverted Hammer, Hanging Man, Spinning Top), two-candle (Engulfing, Near Engulfing, Harami, Kicker, Piercing Line, Dark Cloud Cover, Tweezers, Meeting Lines, Separating Lines, Doji Star), three-candle (Morning/Evening Star, Three White Soldiers, Three Black Crows, Three Inside Up/Down, Three Outside Up/Down, Abandoned Baby, Upside Gap Two Crows), four-candle (Three Line Strike, Concealing Baby Swallow), five-candle (Rising/Falling Three Methods, Mat Hold, Ladder Bottom), and TheStrat composite patterns (2-2, 3-1-2, 2-1-2, 1-2-2 Rev, 1-3 Rev)
• Multi-timeframe backtesting — backtest all 5 timeframes in a single run with per-TF statistics
• Trade management modes — fixed (static SL/TP), breakeven (move SL to entry at 1R), trail (ATR-based trailing stop), partial (close 50% at 1R, trail remainder)
• Structure-based SL placement — place stops at pattern invalidation levels (below Hammer low, below Engulfing candle extreme, etc.) instead of generic ATR offsets
• Equity curve & drawdown — sequential P&L simulation with max drawdown, Sharpe ratio, Calmar ratio, profit factor, and consecutive win/loss streaks
• Timeout classification — choose between marginal (Marginal_Win/Loss based on close vs entry) or expired (flat 0R for all timeouts) for honest win rate reporting
• Multi-symbol watchlist — scan and backtest multiple symbols (e.g. --symbols EURUSD GBPUSD USDJPY)
• Pattern tier system — patterns auto-classified as A:ELITE, B:TRADEABLE, C:MARGINAL, or D:AVOID based on historical win rate
• Session quality classification — sessions ranked as PRIME, FAVORABLE, NEUTRAL, or UNFAVORABLE
• Signal scoring (0-100) — each live signal scored using TF-specific pattern WR, session gradient, confluence bonus, tier bonus, and MFE bonus
• Confluence scoring (0-6 with D1 filter, 0-7 without) — each backtest detection gets a confluence score based on trend alignment, volume, S/R context, RSI extreme, swing level, and session quality (D1 trend factor is skipped when the D1 trend filter is active, since it's already guaranteed)
• Support/Resistance context — swing high/low detection tags each signal as near_support, near_resistance, at_swing_low, or at_swing_high
• RSI context — RSI(14) computed at each detection; oversold/overbought contributes to confluence
• Variable R:R by pattern — configurable rr_by_pattern dict overrides TP multiplier per pattern
• MAE/MFE tracking — Max Adverse Excursion and Max Favorable Excursion in R-multiples per trade
• Time-to-SL/TP — bars until SL or TP hit, enabling trade management optimization
• Exit R tracking — actual R-multiple at trade exit (accounts for breakeven moves, trailing stops, partial closes)
• Open-proximity SL/TP resolution — when both SL and TP are within a candle's range, the level closer to the open price is assumed hit first (replaces the old candle-direction heuristic)
• Wilder's ATR smoothing — standard industry ATR method (alpha = 1/period), matching MT5's built-in indicator
• Enriched stats JSON — latest_stats_multitf.json now includes per-TF patterns, sessions, cross-stats, confluence breakdown, and equity curve metrics
• D1 forward window extended — D1 forward evaluation increased from 5 to 20 candles (4 trading weeks) for meaningful D1 stats
• Historical edge dashboard — displayed at scanner startup showing top setups, pattern x session combos, Tier D avoid list, and recommended live setups
• Per-timeframe WR columns — pattern table shows win rate broken down by M5/M15/H1/H4/D1 so you can see which TF each pattern performs best on
• Stop Loss / Take Profit based on ATR (configurable multiplier, R:R ratio)
• Higher-timeframe ATR for fast timeframes (M5/M15 automatically use H1 ATR for realistic SL/TP)
• Entry verification (stop orders only filled if price touches entry on the next candle)
• Forward evaluation with intra-candle path simulation — avoids look-ahead bias
• R-level tracking (up to R5) and hit-rate analysis
• Volume confirmation (optional)
• D1 trend filter (enabled by default) — requires the daily SMA 20 trend to align with the pattern direction
• Deduplication — picks the highest-priority pattern per candle
• Session classification (Asia, Pacific, London Open, London Morning, London/NY Overlap, NY Afternoon)
• Full backtests over date ranges — CSV reports, summary tables, JSON stats cache, and text reports
• Live scanner — monitors all active timeframes and prints formatted alerts when a new candle closes
• Tier-aware sound alerts (Windows only) — high-Hz triple beep for STRONG BUY, low-Hz triple beep for STRONG SELL; Tier A (Elite) always fires, Tier B only if score ≥ sound_alert_tier_b_min_score (default 60), Tier C/D never; starts muted, type m + Enter to toggle
• Position sizing (risk-based, standard lots) displayed in alerts
• Auto-detected broker UTC offset — broker UTC offset is auto-detected at startup by comparing the latest MT5 candle time against true UTC; handles DST transitions automatically; falls back to broker_utc_offset config value if detection fails
• Local time display — candle close times and "Next close" countdowns are converted from broker time to local machine time for display; log timestamps always use local time
• Auto-reconnect with exponential backoff if MT5 connection drops

Quick Start

Step 1 — Run the Backtest

The backtest generates the probability data that powers the live scanner's pattern tiers, signal scores, and historical edge display. Always run the backtest first.

python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14

This scans all 5 timeframes (M5, M15, H1, H4, D1) over the date range and saves:

• Per-TF CSV files (detections, pattern summary, session summary) in ./backtest_results/
• latest_stats_multitf.json — the enriched stats cache the live scanner loads at startup (now includes per-TF patterns, sessions, cross-stats, confluence breakdown, and equity curve metrics)

With D1 trend filter enabled (default), only signals that aligned with the daily trend are counted. This gives the most accurate stats for live trading.

Step 2 — Run the Live Scanner

python mt5_multitf_pattern_scanner.py --mode live

The scanner starts, loads the backtest stats, and displays the Historical Setups Dashboard:

• Overall and per-timeframe win rates
• Pattern tiers with per-TF WR columns (M5 | M15 | H1 | H4 | D1)
• Session quality rankings
• Top pattern x session combos
• Tier D patterns to avoid
• Recommended live setups with signal scores

Then it monitors all timeframes and alerts on every new candle close when a pattern is detected, showing:

• Pattern name, tier, direction, session, D1 trend alignment
• Entry, SL, TP with pip distances and R:R ratio
• Prob(TP) percentage based on historical SL/TP hit rates
• Historical edge breakdown (pattern WR, session WR, cross-stat WR, signal score)
• Risk-based position sizing

Sound alerts start muted by default. Type m + Enter in the terminal to unmute and hear audio alerts for strong signals. See Sound Alerts for details.

Press Ctrl+C to stop.

Usage

Full Backtest (date-ranged)

Runs a complete backtest across all active timeframes over a specified date range. This is the primary way to generate stats for the live scanner.

# All timeframes, Jan 2025 to May 2026

Quick Backtest (last N bars)

Fast snapshot on the most recent N candles (default 500) for a single timeframe.

python mt5_multitf_pattern_scanner.py --mode backtest --bars 500

Live Scanner

# All timeframes (default)
python mt5_multitf_pattern_scanner.py --mode live

# Specific timeframes
python mt5_multitf_pattern_scanner.py --mode live --timeframes H1 H4 D1

# Without D1 trend filter (must match how backtest was run)
python mt5_multitf_pattern_scanner.py --mode live --no-d1-trend-filter

One-Shot Scan

Scan the latest closed candle on all active timeframes and exit.

python mt5_multitf_pattern_scanner.py --mode scan

Test Sound Alerts

Play both the STRONG BUY and STRONG SELL test beeps to verify audio is working, then exit.

python mt5_multitf_pattern_scanner.py --test-sound

---

Sound Alerts

The scanner includes Windows-only sound alerts so you don't have to stare at the screen waiting for strong signals.

How it works

• STRONG BUY (Bullish signal) — triple high-Hz beep (1200 Hz by default)
• STRONG SELL (Bearish signal) — triple low-Hz beep (400 Hz by default)
• Tier-aware triggering — which patterns fire an alert depends on their tier:
  • Tier A (Elite) — always triggers a sound alert
  • Tier B (Tradeable) — triggers only if the signal score ≥ sound_alert_tier_b_min_score (default 60)
  • Tier C / D — never triggers sound alerts
• The scanner starts muted — you must explicitly unmute to hear alerts
• Type m + Enter in the terminal to toggle mute/unmute at any time
• The keyboard listener runs in a background thread, so there is no delay — it responds instantly

Startup message

When the live scanner starts with sound enabled, you will see:

Sound Alerts: ENABLED | Buy: 1200Hz | Sell: 400Hz | Alert Tier: B (score >= 60)
Sound is MUTED — Type "m" + Enter to unmute

Toggling mute

Type m and press Enter at any time while the scanner is running:

Sound UNMUTED  |  Type 'm' + Enter to toggle
Sound MUTED    |  Type 'm' + Enter to toggle

Testing sound

Before relying on alerts, verify your audio works:

python mt5_multitf_pattern_scanner.py --test-sound

This temporarily unmutes, plays both test beeps, then restores the muted state.

Sound configuration

These settings are in the CFG dict at the top of the script (not exposed as CLI args):

Key	Default	Description
sound_enabled	True	Master switch — set False to disable all sound
sound_buy_hz	1200	Frequency in Hz for STRONG BUY triple beep
sound_sell_hz	400	Frequency in Hz for STRONG SELL triple beep
sound_beep_duration	150	Duration of each individual beep in milliseconds
sound_beep_pause	100	Pause between beeps in milliseconds
sound_alert_tier	'B'	Minimum tier to trigger sound: 'A' (Elite only), 'B' (Tradeable+), 'C' (all directional)
sound_alert_tier_b_min_score	60.0	Minimum signal score for Tier B patterns to trigger a sound alert

v9 Enhancements

Massively Expanded Pattern Library (50+)

v9 adds 30+ new patterns across all candle counts, bringing the total to 50+:

New single-candle patterns: Dragonfly Doji, Gravestone Doji, Bullish Belt Hold, Bearish Belt Hold

New two-candle patterns: Near Engulfing, Piercing Line, Dark Cloud Cover, Bullish Kicker, Bearish Kicker, Meeting Lines (Bullish/Bearish), Bullish/Bearish Separating Lines, Bearish Doji Star

New three-candle patterns: Three Inside Up, Three Inside Down, Three Outside Up, Three Outside Down, Bullish Abandoned Baby, Bearish Abandoned Baby, Upside Gap Two Crows

New four-candle patterns: Bullish/Bearish Three Line Strike, Concealing Baby Swallow

New five-candle patterns: Mat Hold (Bullish/Bearish), Ladder Bottom

TheStrat composite patterns: 2-2 Continuation/Reversal, 3-1-2 Reversal, 2-1-2 Reversal, 1-2-2 Reversal, 1-3 Reversal — based on Rob Smith's TheStrat candle-type system (Type 1 = inside bar, Type 2 = directional break, Type 3 = outside bar)

New pattern thresholds are configurable in CFG:

Key	Default	Description
belt_hold_wick_ratio	0.1	Max wick/body ratio for belt hold patterns
kicker_min_body_ratio	0.6	Min body ratio for kicker candles
separating_lines_tolerance_pips	2	Open price tolerance for separating lines
meeting_lines_tolerance_pips	2	Close price tolerance for meeting lines

Tier-Aware Sound Alerts

Sound alerts are now triggered based on pattern tier rather than a flat score threshold:

Tier	Alert condition
A: ELITE	Always fires a sound alert
B: TRADEABLE	Fires only if signal score ≥ sound_alert_tier_b_min_score (default 60)
C: MARGINAL	Never fires
D: AVOID	Never fires

This replaces the old sound_strong_threshold (65.0) flat cutoff. Configure via sound_alert_tier and sound_alert_tier_b_min_score in CFG.

Auto-Detected Broker UTC Offset

At live scanner startup, the broker's UTC offset is automatically detected by comparing the timestamp of the latest MT5 candle against true UTC. This means DST transitions are handled correctly without any manual configuration change.

• The detected offset is logged at startup: Timestamps: Local time (UTC+3, auto-detected broker UTC+3)
• If detection fails, falls back to the broker_utc_offset value in CFG (default: 2)
• To disable auto-detection, set broker_utc_offset to 0 in CFG

Local Time Display

Candle close times and "Next close" countdowns in the live scanner are now displayed in local machine time rather than broker server time. Log timestamps ([HH:MM:SS]) have always used local time — now the candle times match.

The conversion formula is: local = broker_time − broker_utc_offset + local_utc_offset

v8 Enhancements

Trade Management Modes

The backtest now supports four trade management modes that control how the stop loss is managed after entry:

Mode	Behavior
fixed	Static SL/TP — original behavior, no adjustment (default)
breakeven	Move SL to entry price (breakeven) when price reaches breakeven_at_r R (default: 1.0R)
trail	After price reaches trail_at_r R (default: 1.5R), move SL to breakeven, then trail by trail_atr_mult x ATR behind price
partial	Close partial_close_pct (default: 50%) of position at partial_close_r R (default: 1.0R), move SL to breakeven for remainder, then trail

All modes also support time-based stop tightening: if time_stop_pct (default: 0.7 = 70%) of the forward evaluation window elapses without TP, the SL is tightened to breakeven. This only activates in non-fixed modes.

# Test breakeven mode (move SL to entry at 1R)
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --trade-management breakeven

# Test trailing stop (move to BE at 1.5R, then trail by 1x ATR)
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --trade-management trail

# Test partial close (close 50% at 1R, trail remainder)
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --trade-management partial

New detection columns track trade management outcomes:

Column	Description
Exit_R	Actual R-multiple at trade exit (accounts for BE moves, trailing, partial closes)
SL_Moved_to_BE	True if SL was moved to breakeven during the trade
Partial_Closed	True if a partial position was closed
Remaining_Pct	Fraction of position still open at exit (1.0 = full, 0.5 = half)

Structure-Based SL Placement

Instead of using a generic candle_low - sl_mult * ATR for every pattern, structure-based SL places the stop at the pattern's natural invalidation level — the price level that would invalidate the pattern's signal:

Pattern	Bullish SL Placement
Hammer / Inverted Hammer	Below signal candle's low (the wick IS the pattern)
Morning Star	Below the lowest point of the 3-candle pattern
Three White Soldiers	Below the first candle's low
Bullish Engulfing	Below the engulfing candle's low
Bullish Harami	Below the mother candle's low (previous candle)
Rising Three Methods	Below the first candle's low of the 5-candle pattern
Tweezer Bottoms	Below the lower of the two lows
Default (other)	Below signal candle's low

Bearish patterns use the mirror (above pattern highs). A small buffer (sl_structure_buffer_pips, default: 2 pips) is added below/above the extreme.

# Use structure-based SL instead of ATR-based
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --sl-mode structure

Advantages over ATR-based SL:

• Tighter stops — pattern invalidation is often closer than 1.5x ATR, reducing risk per trade
• Logical levels — the stop has a reason (if the Hammer's low breaks, the pattern is invalidated)
• Pattern-specific — each pattern type gets its own optimal SL level

Equity Curve & Drawdown Analysis

Each backtest timeframe now includes a Section 8: Equity Curve & Drawdown in the report, simulating sequential trading with 1R risk per trade and tracking cumulative P&L in R-multiples.

Metric	Description
Final Equity	Total cumulative P&L in R-multiples
Max Drawdown	Largest peak-to-trough drawdown (R and %)
Max Consec Wins/Losses	Longest winning and losing streaks
Profit Factor	Gross profit / gross loss
Expectancy	Average R per trade
Sharpe Ratio	Annualised risk-adjusted return (assumes ~4 trades/day, 252 days/year)
Calmar Ratio	Annualised return / max drawdown
Avg Win/Loss R	Average R-multiple for wins and losses separately

The equity curve uses the Exit_R column when available (v8 trade management), giving accurate P&L even with breakeven moves and partial closes. For fixed mode, it falls back to deriving R from the outcome type.

Timeout Classification

By default, trades that reach the end of the forward evaluation window without hitting SL or TP are classified as Marginal_Win or Marginal_Loss based on whether the close is above or below entry. This inflates win rates by counting tiny gains (e.g. +0.2R) as full "wins".

The --timeout-mode expired option reclassifies all timeouts as Expired at 0R, giving an honest win rate that only counts actual TP vs SL outcomes:

Mode	Timeout Outcome	Win Rate Meaning
marginal (default)	Marginal_Win (+0.1R to +0.5R) or Marginal_Loss (-0.1R to -0.5R)	Includes near-scratches as wins/losses
expired	Expired (0R)	Only real TP_Hit vs SL_Hit count

# Honest win rates — timeouts = 0R scratch
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --timeout-mode expired

Multi-Symbol Watchlist

The scanner and backtester now support scanning multiple symbols:

# Backtest multiple symbols
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --symbols EURUSD GBPUSD USDJPY

# Live scanner with watchlist
python mt5_multitf_pattern_scanner.py --mode live --symbols EURUSD GBPUSD

By default, only EURUSD is scanned (preserving backward compatibility). The watchlist can also be configured in the CFG dict via the watchlist key.

---

v7 Enhancements

Open-Proximity SL/TP Resolution

When both SL and TP fall within a single candle's range, the old heuristic used the candle's direction (bullish/bearish close) to decide which was hit first — this is look-ahead bias. The new heuristic uses open-proximity: whichever level is closer to the candle's open price was likely hit first. This is more realistic and corrects a 2-5% WR distortion.

Confluence Scoring (0-6 with D1 filter, 0-7 without)

Each backtest detection receives a confluence score based on how many confirming factors align:

Factor	+1 When
Trend alignment	Local trend agrees with trade direction
D1 trend alignment	Daily trend agrees with trade direction (skipped when --d1-trend-filter is active)
Volume confirmation	Signal candle has above-average volume
S/R context	Near support (bullish) or near resistance (bearish)
RSI extreme	RSI < 35 for bullish, RSI > 65 for bearish
At swing level	At swing low (bullish) or swing high (bearish)
Session quality	London/NY Overlap or London Open session

Why skip D1 trend when the filter is active? When --d1-trend-filter is on (the default), every signal already has D1 trend alignment guaranteed by the filter. Counting it as a confluence factor would inflate every score by +1 and destroy score differentiation. With the filter active, the effective range is 0-6; without the filter, it's 0-7.

The backtest report and JSON include confluence breakdowns, e.g. "Confluence >= 4: 72% WR vs Confluence 0-2: 48% WR".

Variable R:R by Pattern

Different patterns have different optimal R:R profiles. Configure overrides in CFG:

'rr_by_pattern': {
    'Bullish Engulfing': 1.5,    # Quick scalp
    'Morning Star': 2.5,         # Larger move expected
    'Three White Soldiers': 3.0, # Strong continuation
},

When a pattern is listed here, its TP multiplier is overridden. The RR_Override column in the detections CSV shows which patterns used overrides.

MAE/MFE Tracking

Every trade now records:

• MAE (Max Adverse Excursion) — worst drawdown in R-multiples before the trade closed
• MFE (Max Favorable Excursion) — best profit in R-multiples before the trade closed

This enables trade management optimization like: "Move SL to breakeven after price reaches 1R" or "If MAE exceeds 0.8R, the trade has low probability of reaching TP".

Time-to-SL/TP

Each trade records Bars_to_SL and Bars_to_TP — the number of forward candles until SL or TP was hit. This enables:

• Early exit strategies: "If not in profit after 8 M5 candles, close for breakeven"
• Trailing stop timing: "Move SL to breakeven after 4 H4 candles"

Support/Resistance Context

The backtest now detects swing highs and lows (using a 5-bar local extreme window over the last 50 bars) and tags each detection with:

• Near_Support — price within 1 ATR of a swing low
• Near_Resistance — price within 1 ATR of a swing high
• At_Swing_Low — candle low is the lowest in the lookback window
• At_Swing_High — candle high is the highest in the lookback window

Patterns near support/resistance have dramatically different win rates.

RSI Context

RSI(14) is computed at each detection using Wilder's smoothing method. The value is stored in the RSI column and contributes to confluence scoring (oversold for bullish, overbought for bearish).

Enriched Stats JSON

latest_stats_multitf.json now includes per-TF breakdown of:

{
  "timeframes": {
    "H4": {
      "overall": { "win_rate": 53.6, "total_signals": 252, "avg_mae_r": 0.45, "avg_mfe_r": 0.72, "avg_bars_to_tp": 5.2 },
      "patterns": { "Bullish Engulfing": { "win_rate": 58.2, "total": 312 } },
      "sessions": { "London/NY Overlap": { "win_rate": 55.1, "signals": 89 } },
      "cross": { "Bullish Engulfing|London/NY Overlap": { "win_rate": 62.3, "signals": 14 } },
      "confluence": { "3": { "win_rate": 68.2, "signals": 42 }, "0": { "win_rate": 44.1, "signals": 31 } },
      "equity": { "final_equity_r": 12.5, "max_dd_r": -4.3, "sharpe": 1.8, "calmar": 2.1 }
    }
  }
}

The live scanner now loads all data from JSON — no CSV re-parsing at startup, so the scanner starts instantly.

Improved Signal Scoring

The v7 score formula fixes the old formula's problems:

Factor	v6 (old)	v7 (new)
Base	WR * confidence (low-sample patterns got lower base)	Raw WR as base (no multiplication)
Sample size	Confidence multiplier	Sample penalty (-15 for small samples, 0 for 30+)
Session	Binary +10/-10	Proportional gradient based on session WR
R-factor	min(amr, 2.0) * 10 (up to +20, too large)	MFE bonus +1/+3 for amr >= 0.5/0.8
Confluence	Not used	+5 if high-confluence signals have WR >= 55%
TF-specific	Used merged stats	Prefers TF-specific stats when available

D1 Forward Window Fix

D1 forward evaluation was only 5 candles (5 trading days). Since D1 ATR-based SL/TP often needs 2-4 weeks to resolve, this produced meaningless D1 stats (avg_max_r = 0.12R was an artifact). Now set to 20 candles (4 trading weeks).

Wilder's ATR Smoothing

ATR now uses Wilder's exponential smoothing (alpha = 1/period) instead of simple moving average. This matches MT5's built-in ATR indicator and the industry standard. The difference from SMA can be 5-15% on SL/TP sizing.

---

How Backtest Stats Flow Into the Live Scanner

1. Backtest creates per-TF CSV files and the enriched latest_stats_multitf.json (includes per-TF patterns, sessions, cross-stats, confluence breakdown, and equity metrics)
2. Live scanner calls load_latest_backtest_stats() at startup, which:
   • Reads latest_stats_multitf.json — if it has per-TF pattern/session/cross data (v7+), loads directly without CSV parsing
   • Falls back to CSV parsing only for older JSON formats
   • Caches results for 4 hours (configurable via stats_cache_hours)
3. Dashboard displays: overall WR, per-TF WR table, pattern tiers with per-TF columns, session quality, top cross-stats, avoid list, recommended setups
4. Each live signal is enriched with: pattern tier badge, quality summary line, Prob(TP), historical edge breakdown, TF-specific signal score, and confluence context

Important

: The D1 trend filter setting must match between backtest and live mode. If you run the backtest with --d1-trend-filter (default), run live with --mode live (also default). If you run backtest with --no-d1-trend-filter, run live with --no-d1-trend-filter.

Signal Scoring System

Each live signal is scored 0-100 based on:

Factor	Description
Base score	Raw pattern win rate (0-100)
Sample penalty	-15 to 0 based on sample size (0 at 30+ signals, -20 below minimum)
Session gradient	Proportional bonus/penalty based on session WR (e.g., +8 at 60% WR, -8 at 40% WR)
Confluence bonus	+5 if high-confluence signals (score >= 3) have WR >= 55%
Tier bonus	+5 for Tier A, +3 for Tier B
MFE bonus	+1 for avg_max_r >= 0.5, +3 for >= 0.8

Per-TF scoring: When tf_label is available (live scanner), the score prefers TF-specific pattern stats over merged aggregate stats. A Bullish Engulfing on H4 (58% WR) gets a different score than the same pattern on M5 (52% WR).

Patterns below --min-signal-score are filtered out (default: 0, i.e. show all).

Pattern Tiers

Tier	WR Range	Meaning
A: ELITE	>= 58% AND n >= 30 AND avg_max_r >= 0.35	Highest edge, trade with confidence
B: TRADEABLE	>= 50% AND n >= 10 AND avg_max_r >= 0.25	Solid edge, reliable setups
C: MARGINAL	>= 40%	Use only with strong confluence
D: AVOID	< 40% OR insufficient data	Negative edge, skip these

Timezone Notes

• Log timestamps ([HH:MM:SS]) use your local computer time
• Candle close times and "Next:" candle times are converted to local computer time via the auto-detected broker UTC offset
• Session classification uses broker server time hours internally
• The broker UTC offset is auto-detected at startup; if detection fails, the broker_utc_offset config value is used (default: UTC+2)
