Initial commit: orderflow analysis system with 5 pattern detectors

Browse Source 
Real-time orderflow trading system with absorption, initiative, sweep,
exhaustion, and divergence detection. Features volume profile framing,
state machine trade lifecycle, MT5 + Bybit feeds, FastAPI dashboard,
and Telegram alerts for 30+ instruments.

Profile Framing — Daily Bias Engine
Implements Fabio's profile framing methodology for determining directional bias.
Core logic:
1. Build daily cash-session volume profiles
2. Classify profile shape → P-shape (long), b-shape (short), D (neutral), double (transition)
3. Track value acceptance/rejection across days
4. Merge overlapping profiles (2-3 days) for refined VAL/VAH
5. Detect market shifts: failed auctions, hooks, distribution warnings
6. Output: daily bias direction + qualified levels for orderflow execution
