URGENT — Review & Certify MT5 Risk Firewall + Telegram Module (5 Days)

We have a professionally built MT5 security and monitoring module with pre-written code. We need an experienced MQL5 developer to REVIEW, FIX, and CERTIFY the SENTINEL MODULE.

YOU ARE NOT BUILDING FROM SCRATCH.

You are reviewing 6 existing .mqh files.

WHAT YOU WILL DO:

1. Review 6 pre-written Sentinel module files

2. Verify drawdown calculations (3% daily / 7% total)

3. Fix DD warning spam bug (fires every tick — needs 5-minute cooldown between warnings)

4. Certify Telegram WebRequest rate limiting works

5. Verify emergency close works without engine lock

6. Write 1 test script proving DD math is correct

FILES YOU WILL RECEIVE:

- AlmudoSentinel_Types.mqh (READ ONLY - do not change)

- AlmudoSentinel_Firewall.mqh (Review and fix)

- AlmudoSentinel_EmergencyClose.mqh (Review and fix)

- AlmudoSentinel_Telegram.mqh (Review and fix)

- AlmudoSentinel_Callback.mqh (Review and fix)

- AlmudoSentinel.mqh (Review and fix)

STRICT NON-NEGOTIABLE RULES:

- WebRequest ONLY for Telegram (no DLL imports)

- OnPreExecutionCheck() MUST return false when drawdown >= daily limit (3%) or total limit (7%)

- Emergency close must work WITHOUT engine lock

- State machine: GREEN/YELLOW/ORANGE/RED/BLACK exact

- Zero compilation warnings

- NDA must be signed before code is shared

KNOWN BUG (Priority Fix):

DD warning Telegram message fires every tick when position is open and drawdown >= 75% of limit. Fix: Add 5-minute timestamp cooldown so warning only sends once per 5 minutes maximum.

DELIVERABLES:

- All 6 certified .mqh files (5 days)

- 1 test script with DD math proof

- Changelog documenting every fix

MILESTONE PAYMENT STRUCTURE:

- Day 2: Firewall + DD calculations ($30)

- Day 4: Telegram + Callback bridge ($30)

- Day 5: Full Sentinel + spam fix + test ($40)

SCREENING QUESTION (must answer to be considered):

DayStart equity = $10,000. Current equity = $9,700. What is the daily drawdown percentage? Show your formula step by step.
