📊 Key Implementation Decisions

Architecture: Monolithic with Parallel Arrays

Rationale: MT4 reliability, proven approach, simpler debugging

Data Structure: Separate Arrays per Timeframe

Rationale: Clear separation, easy indexing, no struct issues

Order Type: Stop Orders (Not Limits)

Rationale: Strategy requires breakout entry, not pullback entry

No Dynamic Risk Management (MVP)

Rationale: Keep MVP simple, add in future enhancement

Single File Implementation

Rationale: Easier deployment, no include dependencies, MT4 compatibility
