Customizable Expert Advisor – WIN$N (Hedging), Magic Filter, TP Multiplier, Expressions R1–R9

I need a modular and customizable Expert Advisor to trade the Brazilian mini index (WIN$N) on a hedging account, with the following features:

• Entry logic via expressions (configurable input fields)

• Entry: market execution

• Exit (TP, SL): always via limit order (on the book)

• Evaluate conditions on every tick, but only using closed candles (e.g., C[1], O[1])

• Magic Number (user-defined) to separate trades and stats per strategy

• Display daily, monthly and total profit on chart (per Magic Number)

Additional parameters:

• Expression fields: R1 to R9

• LOSSCONSEC : counts consecutive losses (reset after gain)

• ULTRESULT : last closed trade result

• Fixed base lot size ( BASE_LOT ) as a separate input (e.g., 1)

  • This must be configurable manually through the input panel

  • Typical use: set BASE_LOT = 1 , and control the actual lot using the formula below

• Lot multiplier formula (e.g., FINAL_LOT = BASE_LOT * R1 )

• Fixed Stop Loss value (editable input, e.g., 200)

• TP = SL * expression

I’d like to receive the .mq5 source code so I can improve or adapt it in the future if needed.

Only apply if you have experience developing EAs with expression-based logic and multi-strategy compatibility (Magic Number handling).
