Техническое задание

Project: Donchian Breakout – Fully Mechanical System
Platform: MetaTrader 5
Timeframe: H1 Only

General Description

Develop a fully automated MT5 Expert Advisor implementing a mechanical Donchian breakout strategy with ATR-based trailing stop.

The EA must operate independently per symbol and be suitable for 24/7 VPS execution.

No discretionary logic. No time filters.

Trading Symbols

The EA must function correctly on:

  • EURUSD (Forex CFD)

  • US500 (Index CFD)

  • XAUUSD (Gold)

Each chart runs independently.
Maximum 1 open trade per symbol.

Timeframe Restriction

  • EA must operate ONLY on H1 chart.

  • If attached to another timeframe, EA must not trade.

Trading Signals

Indicator Definitions

  • Donchian Channel Period: 20 (default, editable)

  • ATR Period: 20 (default, editable)

  • ATR Multiplier: 2.5 (default, editable)

All indicators calculated using CLOSED candles only.

Long Entry Condition

  1. A candle CLOSES above the previous 20-period Donchian High.

  2. Entry executed at market open of the next candle.

  3. Only if no open trade exists for that symbol.

Short Entry Condition

  1. A candle CLOSES below the previous 20-period Donchian Low.

  2. Entry executed at market open of the next candle.

  3. Only if no open trade exists for that symbol.

Important Signal Rules

  • Breakout must be based on CLOSED candle only.

  • No intra-candle triggers.

  • Must prevent duplicate entries from same breakout candle.

Position Sizing

  • Risk per trade: 0.5% of account balance (editable input)

  • Stop distance determined by ATR-based initial stop

  • Lot size calculated automatically based on:

    • Stop distance

    • 0.5% account risk

    • Symbol contract specifications

Must work correctly for indices and gold.

Stop Loss & Trailing Logic

Initial Stop Loss

  • Set at 2.5 × ATR(20)

  • Based on ATR value of most recently closed candle

Trailing Stop

  • Dynamic trailing stop based on 2.5 × ATR(20)

  • Stop must only move in profit direction

  • Stop must never widen

  • Trailing updates on every tick (preferred)

Trade Management Rules

  • Maximum 1 open trade per symbol

  • No pyramiding

  • No time filters

  • No news filters

  • New trade only after previous position fully closed

  • Magic number input required

Inputs (Editable Parameters)

  • Risk % (default 0.5%)

  • Donchian Period (default 20)

  • ATR Period (default 20)

  • ATR Multiplier (default 2.5)

  • Slippage

  • Magic Number

Error Handling & Safeguards

  • Prevent duplicate entries on same candle

  • Must handle broker requotes

  • Must function correctly after terminal restart

  • Must not open multiple trades accidentally

  • Must log errors clearly in Experts tab

Deliverables

  • Compiled .ex5 file

  • Full source code (.mq5)

  • Clear instructions for installation

  • Commented code

Testing & Acceptance

The EA must be tested on demo account.

Payment will only be released after:

Please confirm:

  • Estimated delivery time
