MT5 Expert Advisor – "RANGER" Range Reversion Strategy

Description:

I need an MT5 Expert Advisor built to exactly replicate a TradingView Pine Script strategy.

This is a range mean reversion system.
All logic must be followed precisely. No optimisation, no interpretation.

The EA must behave identically to the logic below.

Market & Timeframe

• Primary: NAS100 (but must work on any symbol)
• Timeframe: 5-minute
• Must work regardless of broker (handle symbol digits properly)

Core Strategy Logic

1. Indicators

• EMA 20
• EMA 200
• RSI (14)

2. Range Detection

Calculate:

• Range High = highest high over last 20 candles
• Range Low = lowest low over last 20 candles
• Range Mid = (high + low) / 2

3. Market Condition (Ranging Only)

Trade ONLY if:

• Absolute distance between EMA 20 and EMA 200 ≤ 35 points
• Absolute slope of EMA 200 over last 10 bars ≤ 10 points

4. Entry Conditions

Long Entry:

• Price LOW touches or goes below (Range Low + 5 points)
• Candle closes back above Range Low
• Lower wick > candle body (wick rejection)
• RSI ≤ 30

Short Entry:

• Price HIGH touches or goes above (Range High - 5 points)
• Candle closes back below Range High
• Upper wick > candle body
• RSI ≥ 70

5. Trade Management

Stop Loss:

• Long: Range Low − 5 points
• Short: Range High + 5 points

Take Profit:

• Long: Range Mid
• Short: Range Mid

6. Position Sizing (CRITICAL)

Each trade must risk a fixed % of account balance:

• Risk per trade = 1% of equity
• Lot size must be calculated based on stop distance

7. Trade Execution Rules

• Only ONE open trade at a time
• No hedging
• No pyramiding

8. Re-entry Rule (VERY IMPORTANT*)

• If a LONG trade is taken, no further LONG trades allowed until a SHORT trade occurs
• If a SHORT trade is taken, no further SHORT trades allowed until a LONG trade occurs

This is a hard rule, not time-based.

9. Execution Details

• Execute trades at candle close only
• No intra-candle execution
• Use completed bar data only

10. Additional Requirements

• Must work on live account and strategy tester identically
• Must handle different broker digits (e.g. 2, 3, 5 digit pricing)
• No repainting logic
• EA must not open duplicate trades
• Magic number must be configurable

Deliverables

• Fully working .ex5 file
• Source code (.mq5)
• Clear instructions for setup
• Must match TradingView behaviour logically

Important Notes

• Do NOT optimise or change the strategy
• Do NOT add filters or improvements
• Follow the logic exactly as written
