-# mt5-candlestick-scanner-backtester
-Multi‑timeframe candlestick pattern scanner & backtester for MetaTrader 5 (supports M5, M15, H1, H4, D1 with ATR‑based stop losses, forward evaluation, R‑level tracking, and live alerting)
+# 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 alerts when a new pattern appears.
+
+**Features**
+
+- 20+ patterns: Doji, Hammer, Engulfing, Morning/Evening Star, Three White Soldiers, Marubozu, Harami, Tweezers, Rising/Falling Three Methods, etc.
+- Stop Loss / Take Profit based on **ATR** (configurable multiplier, R:R ratio)
+- **Higher‑timeframe ATR** for fast timeframes (M5/M15 automatically use H1 ATR → realistic SL/TP)
+- **Entry verification** (stop orders only filled if touched on 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** and **D1 trend filter**
+- **Deduplication** – picks the highest‑priority pattern per candle
+- **Session classification** (Asia, London, NY, etc.)
+- **Full backtests** over date ranges → CSV reports, summary tables, and text reports
+- **Live scanner** – monitors all active timeframes and prints formatted alerts when a new candle closes
+- **Position sizing** (risk‑based) displayed in alerts

+## Installation
+

+
+2. **Install Python dependencies**:
+   pip install MetaTrader5 pandas numpy colorama python-dotenv
+
+3. Clone this repository (or copy mt5_multitf_pattern_scanner.py into a folder).
+
+4. Create a .env file in the same directory as the script, containing your MT5 login credentials:
+.env
+MT5_PATH=C:\Program Files\Broker\terminal64.exe
+MT5_ACCOUNT=12345678
+MT5_PASSWORD=YourPassword

+5. Run the script (see usage below).
+
+Basic Usage
+Live Scanner (default)
+Monitors all active timeframes (M5, M15, H1, H4, D1) and prints alerts whenever a new candle closes and a pattern is detected.
+
+python mt5_multitf_pattern_scanner.py
+To scan only specific timeframes:
+
+python mt5_multitf_pattern_scanner.py --timeframes H1 H4 D1
+Press Ctrl+C to stop.
+
+One‑Shot Scan
+Scan the latest closed candle on all active timeframes and exit.
+
+
+python mt5_multitf_pattern_scanner.py --mode scan
+Quick Backtest (last N bars)
+Simulate patterns on the most recent N candles (default 500) for a given timeframe.
+Useful for a fast performance snapshot.
+
+python mt5_multitf_pattern_scanner.py --mode backtest --bars 500 --timeframes H4
+Full Backtest (date‑ranged)
+Run a complete backtest over a specified date range.
+Generates CSV files (detections, pattern summary, session summary) and a detailed text report.
+
+
+# Backtest all timeframes for the full year 2025
+python mt5_multitf_pattern_scanner.py --mode fullbacktest --from 2025-01-01 --to 2025-12-31
+
+# Backtest only H4 with D1 trend filter and volume filter enabled
+python mt5_multitf_pattern_scanner.py --mode fullbacktest \
+    --timeframes H4 \
+    --from 2025-01-01 --to 2025-12-31 \
+    --d1-trend-filter --volume-filter
+Output directory: ./backtest_results/ (can be changed with --output).
