MT5 Multi-Timeframe Candlestick Pattern Scanner & Backtester
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
- 20+ patterns: Doji, Hammer, Shooting Star, Engulfing, Morning/Evening Star, Three White Soldiers, Three Black Crows, Marubozu, Harami, Tweezers, Rising/Falling Three Methods, Inverted Hammer, and more
- Multi-timeframe backtesting — backtest all 5 timeframes in a single run with per-TF statistics
- 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 pattern tier, session quality, cross-stat edge, and historical win rate
- 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
- Sound alerts (Windows only) — high-Hz triple beep for STRONG BUY, low-Hz triple beep for STRONG SELL; starts muted, type
m+ Enter to toggle - Position sizing (risk-based, standard lots) displayed in alerts
- 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 stats cache the live scanner loads at startup
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
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14
Specific timeframes only
python mt5_multitf_pattern_scanner.py --mode fullbacktest --timeframes H4 D1 --from 2025-01-01 --to 2026-05-14
With D1 trend filter ON (default) and volume filter
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --d1-trend-filter --volume-filter
Without D1 trend filter
python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2026-05-14 --no-d1-trend-filter
Output: ./backtest_results/ (change with --output)
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 with score >= 65) — triple high-Hz beep (1200 Hz by default)
- STRONG SELL (Bearish signal with score >= 65) — triple low-Hz beep (400 Hz by default)
- 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 | Threshold: 65 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_strong_threshold |
65.0 |
Signal score must be >= this to trigger a sound alert |
How Backtest Stats Flow Into the Live Scanner
- Backtest creates per-TF CSV files (
*_detections.csv,*_pattern_summary.csv,*_session_summary.csv) andlatest_stats_multitf.json - Live scanner calls
load_latest_backtest_stats()at startup, which:- Reads
latest_stats_multitf.jsonfor per-TF overall stats - Reads ALL per-TF CSVs to compute merged pattern stats, session stats, and cross-stats (pattern x session)
- Caches results for 4 hours (configurable via
stats_cache_hoursin.env)
- Reads
- Dashboard displays: overall WR, per-TF WR table, pattern tiers with per-TF columns, session quality, top cross-stats, avoid list, recommended setups
- Each live signal is enriched with: pattern tier badge, quality summary line, Prob(TP), historical edge breakdown, and signal score
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 | Weight | Description |
|---|---|---|
| Pattern win rate | Confidence-weighted | Higher WR patterns score more, with a confidence boost for more signals |
| Pattern tier | Tier bonus | A:ELITE gets highest bonus, D:AVOID gets penalty |
| Session quality | Session bonus | PRIME > FAVORABLE > NEUTRAL > UNFAVORABLE |
| Cross-stat edge | Combo bonus | Pattern x session combos with high WR get a bonus |
| Avg Max R | Edge factor | Higher average max R-multiple indicates better profit potential |
Patterns below --min-signal-score are filtered out (default: 0, i.e. show all).
Pattern Tiers
| Tier | WR Range | Meaning |
|---|---|---|
| A: ELITE | >= 57% | Highest edge, trade with confidence |
| B: TRADEABLE | 52-57% | Solid edge, reliable setups |
| C: MARGINAL | 45-52% | Use only with strong confluence |
| D: AVOID | < 45% | Negative edge, skip these |

Timezone Notes
- Log timestamps (
[HH:MM:SS]) use your local computer time - Candle close times and "Next:" candle times use broker server time
- Session classification uses broker server time hours
- This means candle times will differ from your local clock by your timezone offset
