Custom EA Builder
Turn Your Trading Idea Into a Working MT5 Expert Advisor
You have the strategy. We have the expertise. Custom EA Builder is Ofx Trading Systems' premium custom EA development service. We take your trading logic, whether it's a breakout system, a mean-reversion model, a grid variant, or a prop firm challenge strategy, and build it into a fully functional MetaTrader 5 Expert Advisor, tested and delivered ready to deploy.
How It Works
From idea to working Expert Advisor in four clear steps.
Submit Your Idea
Fill out our Strategy Intake Form with your entry/exit logic, risk rules, instruments, and timeframe. This helps us understand your vision before any call.
Strategy Consultation ($99)
Book a 1-hour consultation where we review your logic, stress-test assumptions, identify gaps, and define the exact specification. The $99 fee is fully deducted from your build cost if you proceed.
