HFT Expert Advisor – Demo-to-Live Execution Optimization (MQL5/MT5)

MQL5 Autre Forex Strategy optimization Statistics and mathematics Strategy modules Collection of data on the internet Data mining OpenCL

Spécifications

Situation:

I have developed a highly profitable HFT EA that performs consistently in demo and passes most prop-firm requirements. Short live phases showed profitability but not reproducibly over time. My goal: stable live performance on retail accounts, not prop-firm qualification.

Already tested:

  • Multiple brokers including 3-digit brokers (Exness)
  • IC Markets Raw Spread + IC Markets VPS (0.35 ms latency)
  • Various symbols and timeframes

Suspected root causes to investigate: Slippage & requote handling, spread widening, demo-vs-live tick feed differences, execution mode (Market/Exchange/Request), last-look / asymmetric slippage, partial fills, latency-sensitive entry/exit logic.

Scope of Work:

  1. Code review of existing EA (NDA required before handover)
  2. Identify components failing under live conditions
  3. Restructure entry/exit logic for real spread/slippage robustness
  4. Integrate realistic backtest framework (variable slippage, spread, execution delay, requotes)
  5. Add protective filters: spread, news, session, latency monitoring
  6. Build live-vs-demo execution logger (expected vs. actual fills)
  7. Ongoing iterative collaboration – not a one-time fix

Developer Requirements:

  • Proven HFT / scalping EA experience in live environments (references required)
  • Deep knowledge of broker execution models (A-Book, B-Book, STP, ECN)
  • Tick-data backtesting at ≥99% modeling quality (Dukascopy / real ticks)
  • Experience with slippage modeling and execution-delay simulation
  • MQL5 required

Please include in your proposal: References, estimated hours, fixed price or capped hourly rate, availability for iterative work, own MT5 live account for testing.

Not looking for: Developers without live HFT execution experience, generic EA optimizers, or curve-fitting-based proposals.

Bonus: If the delivered work achieves excellent live performance, I will personally add a $500 bonus on top of the agreed price as a reward for outstanding execution.

Note: I am an experienced trader (6 years Forex/Gold) and technically competent – I expect substantive, reasoned proposals.

Need MQL5 developer for custom semi-auto US30 ICT/SMC EA 400 - 700 USD
Budget depends on experience and quality. I prefer to start with a semi-auto version first, and later upgrade to a full-auto version if the logic works correctly. I need a custom semi-automatic MT5 Expert Advisor for US30 based on an ICT/SMC-style workflow. This is NOT a martingale, grid, scalping spam, or arbitrage bot. I want a clean semi-auto trading assistant that helps me identify and execute high-quality setups
