Case Study ยท Prop Firm EA

Prop Firm Challenge EA Development

A trader attempting funded-account challenges wanted to automate a proven strategy while strictly respecting a prop firm daily-loss and maximum-drawdown rules.

Overview

A trader attempting funded-account challenges wanted to automate a proven strategy while strictly respecting a prop firm daily-loss and maximum-drawdown rules.

The challenge

Prop firms enforce hard limits: breach the daily loss or overall drawdown and the account fails instantly. The EA had to enforce these rules automatically and stop trading before any breach.

Our solution

We built an MT5 EA with a dedicated risk module that tracks daily loss, total drawdown and consistency, halting new trades before thresholds are hit, with presets mapped to the specific firm rules.

How we delivered it

  • Mapped the firm daily-loss, max-drawdown and consistency rules into hard constraints.
  • Coded the strategy with an enforcing risk layer around it.
  • Backtested against challenge-style constraints to confirm rule adherence.
  • Tuned lot sizing to balance target progress against risk limits.
  • Delivered with documentation and firm-specific presets.

The outcome

  • The EA halts trading before breaching daily-loss or drawdown limits in testing.
  • Risk presets can be re-mapped to different prop firms.
  • Client automates the strategy with rule enforcement built in.
