BlackboxAI 0206ef7cbb Initial commit: orderflow analysis system with 5 pattern detectors
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.

Exhaustion Detector
Detects declining volume/delta while price continues making new extremes.
From Fabio:
"Decreasing volume — the aggression of market participants from the volume standpoint
is getting lower and lower. And we have a contrarian imbalance at the top from the sellers.
Price going up up up not being followed by the volume — this divergence."
"The market is pushing really strong, printing another green candle, but the volume
is getting lower and lower. This is a dry up in volume. Usually what you see is
a sudden reversal in price."
Logic:
Price making new extremes + DECLINING effort (volume & delta) = EXHAUSTION
→ EXIT signal or REVERSAL setup
