Add Cumulative Drawdown From Peak Protection to Existing MT5 EA

Hello,

I have an existing MT5 Expert Advisor for XAUUSD. I need one specific protection feature added only.

Task:
Add a modular ON/OFF “Cumulative Drawdown From Peak” protection to my current EA.

Important:
Do not change the trading strategy.
Do not change entry logic.
Do not change exit logic.
Do not change EMA, ADX, session filter, Sell Hour Filter, lot sizing, SL/TP, BreakEven, or Trailing settings.
This job is only for adding the cumulative drawdown protection.

Required Inputs:

1. UseCumulativeDDProtection = true/false

2. CumulativeDD_MaxPercent = configurable percentage

3. CumulativeDD_Action = stop new entries only / close all bot positions and stop

4. ResetPeakMode = never reset / daily reset / manual reset if possible

Required Logic:

1. Track the highest account equity peak since the EA started or since reset.

2. Calculate current drawdown from that peak.

3. If drawdown from peak reaches the configured limit, the EA must block new trades.

4. Optional setting: close all bot-managed positions when the limit is reached.

5. The protection must affect only this EA’s trades if possible, using Magic Number.

6. The protection must be safe after MT5 restart. If possible, store/recover the equity peak using Global Variables or another reliable method.

Required Logs:
The EA must print clear logs such as:

• CUM_DD_PEAK_UPDATED

• CUM_DD_CURRENT

• CUM_DD_LIMIT_HIT

• CUM_DD_NEW_ENTRIES_BLOCKED

• CUM_DD_POSITIONS_CLOSED

Deliverables:

1. Updated MQ5 file with a new version name:
   EA_Trend_Advanced_v2_70_CumulativeDD_TEST.mq5

2. Updated MQH file only if necessary.

3. No unnecessary code rewrite.

4. A short explanation of every block of code changed.

5. Screenshot or confirmation that the EA compiles with 0 errors and 0 warnings.

6. The original v2.69 logic must remain unchanged except for this new protection feature.

I will provide the current EA files after accepting the developer.
