Create Robot EA for Trading

I'm looking for a single MQL5 developer to build a family of Expert Advisors designed specifically to pass and maintain prop firm challenges (1-Step and 2-Step formats, e.g. FundedNext, FTMO-style rules). Key requirements: - Strategy must respect standard prop firm rules: daily loss limit (typically 5%), maximum total loss limit (typically 10%), and phase profit targets (typically 8% then 5%) - Target monthly return: 5-10%, consistent and repeatable — not a one-time lucky run. The strategy must stay safely under the daily loss limit at all times, even during losing streaks - No martingale, no grid, no recovery trades that increase exposure after a loss — capital preservation and rule compliance come first - Strategy logic should be simple and maintainable, not an overly complex black-box system — I need to understand and audit the logic - Must include account-size locking: the EA should verify account balance/equity and only operate within an authorized range (I'll need versions calibrated for $50K, $100K, and $200K accounts) - Licensing: account-bound, with subscription/expiry validation This EA is separate from another personal-trading EA project I have (different developer, different purpose) — this specific role is only for prop-firm-challenge-focused EAs. To apply, please answer directly: 1. Have you built EAs specifically designed to pass prop firm challenges before? Examples welcome. 2. How do you keep a strategy targeting 5-10%/month safely under a 5% daily loss limit? 3. Can you provide a verifiable backtest (3+ years) and are you open to a demo forward-test (2-4 weeks) before final payment? 4. Estimated cost for the base EA plus 3 account-size variants ($50K/$100K/$200K)? Looking for one developer to own this entire product line long-term — ongoing maintenance and adjustments included. Budget: open to discussion based on your approach and experience.
