Create EA from two indicators for MT4

I would like to develop an Expert Advisor with the following rules and features:

1️⃣ Trade Signals

1. Indicator A: when it generates a signal, the possibility to open a trade is activated.

2. Indicator B: must confirm the signal within a maximum of 10 candles from Indicator A.

   • Important: The signal from Indicator B is valid only after the candle that generates it has closed. Open candles do not generate a valid confirmation.

2️⃣ Confirmation Candle Filter

• Measure the size of the confirmation candle of Indicator B (high - low in pips).

• If the candle exceeds a user-configurable maximum value, do not open the trade.

• This avoids entries on overly large candles, which often anticipate retracements.

3️⃣ Stop Loss / Take Profit

• SL:

  • Default below the lowest of the last 10 candles (long) or above the highest of the last 10 candles (short).

  • Ability to add a user-configurable buffer.

  • Ability to set the stop in pips instead of using the min/max of the last 10 candles.

• TP:

  • Default twice the stop loss, but both SL and TP can be manually modified by the user before opening the trade.

  • Ability to set take profit directly in pips as a user-configurable input.

• Trailing Stop: optional, configurable by the user.

• Break-even: move SL to breakeven after a certain number of pips of profit (configurable input).

4️⃣ Money Management

• Lot size:

  • Fixed lot

  • Percentage of account balance/risk (% risk per trade)

• Max daily profit: block new trades if reached.

• Max daily loss: block new trades if reached.

5️⃣ News Filter

• Do not open trades during major economic events.

• Ability to select the impact level (high, medium, low).

• Optional post-news timeout configurable by the user.

6️⃣ Additional Parameters

• Magic Number: specific (e.g., 123456).

• Ability to enable/disable all advanced features by the user.

• Logging of trades, signals, and parameters used (optional for debugging and optimization).
