Strategy Logic

Phase 1 — Range Formation

Market open: 1:02 AM server time
First 1H candle → defines initial support (low) and resistance (high)

Phase 2 — Range Confirmation

Wait for N consecutive candles to close WITHIN the range
Default N = 3 (user-adjustable)
Range becomes "final" only after consolidation confirmed

Phase 3 — Signal Generation

Signal 11  → Price BREAKS ABOVE resistance  → BUY
Signal 10  → Price BREAKS BELOW support     → SELL
Signal 0   → No breakout                    → No trade
