An expert trading bot

I have a working MetaTrader 5 Expert Advisor already coded and running -- this is not a "build from scratch" job. The EA trades a smart-money-concepts style model (structure breaks, liquidity sweeps, order blocks, fair value gaps, optimal trade entry retracement). Exact parameters and the rest of the underlying logic are proprietary and will only be shared once we're under a working agreement.

To check you actually know this space, briefly describe in your reply: what a fair value gap is, what "optimal trade entry" means in an SMC/ICT-style model, and how you'd detect a liquidity sweep programmatically in MQL5. Generic answers or copy-pasted definitions will be skipped.

Work needed:

1. Code review/QA of the existing EA -- correctness, edge cases, MT5-specific pitfalls

2. Harden live execution against real broker conditions: order rejections, market-hours/session gaps, slippage vs backtest fills

3. Run the MT5 Strategy Tester's Optimization module against an existing parameter set and help interpret the results

4. Extend testing/support to additional symbols and timeframes beyond the current set

5. Availability for ongoing paid work as the project develops (broker/API integration, maintenance, new features)

You should have real, demonstrable MQL5/MT5 experience -- especially with the Strategy Tester's Optimization module -- and be comfortable reviewing and extending someone else's codebase rather than only building your own from a blank file. Confidentiality is expected.
