EA Brief – Bi-Weekly Time/Success-Ratio Volume Trigger Strategy

To design and implement a profitable Expert Advisor (EA) that trades based on time-of-day signals, historical success ratio, and a volume-based trigger. The system adapts over a bi-weekly performance evaluation window to optimize entry conditions.

Core Logic

1. Time-of-Day Filter

   • EA only trades within user-defined trading sessions (e.g., London Open, NY Open, Asia Session).

   • Configurable start/end time (broker time).

2. Success Ratio Filter

   • Tracks historical trade performance segmented by session/time-of-day.

   • Calculates win-rate (%) over the last X trades or X days.

   • Minimum success threshold required before allowing new trades (e.g., >55% win-rate for that session).

   • Resets/adapts every bi-weekly period (14 days).

3. Volume Trigger

   • Confirms trades only when tick/market volume exceeds a set threshold (to avoid low-liquidity chop).

   • User-defined input for minimum volume.

   • Option to use relative average volume (e.g., >1.2x the 20-bar average).

4. Bi-Weekly Threshold Management

   • EA evaluates performance every 14 days:

     • If net profit > threshold → continue/scale trading size.

     • If net profit < threshold → reduce risk or pause trading until conditions reset.

   • Keeps trade frequency and drawdown controlled.

Trade Entry & Exit

• Entry Logic

  • If within time filter AND success ratio condition met AND volume trigger active → allow trade entry.

  • Underlying strategy can be configurable (breakout, trend-following MA cross, or mean reversion).

• Exit Logic

  • Fixed TP/SL in pips or % of ATR.

  • Option for trailing stop and/or break-even shift.

Risk Management

• Fixed % risk per trade (default: 1%).

• Daily loss limit.

• Max trades per session/day.

• Bi-weekly drawdown cap: stop trading if equity falls >X% within evaluation period.

Key Inputs (User Parameters)

• Session Times (Start/End in broker time).

• Min Win Rate % (e.g., 55%).

• Lookback Period for success ratio (trades or days).

• Volume Threshold (absolute or relative).

• Bi-Weekly Thresholds (profit/loss cutoffs).

• Risk per trade (% or lot size).

• TP/SL (fixed or ATR-based).

• Max trades per session/day.

Reporting / Dashboard

• On-screen panel showing:

  • Current session status (Active/Inactive).

  • Success ratio for last 14 days.

  • Volume status (Pass/Fail).

  • Bi-weekly P/L performance.

• Logs all trades with tags: session, success ratio at entry, volume condition.

Platforms

• To be implemented in MT4/MT5 (MQL4/5).
