volatile/calm) producing meaningful SMA, EMA, MACD, RSI, Bollinger
Band signals embedded in snapshots
- Rename source CLEARINGHOUSE → CLRH in order messages

Fix MDF order book depth and CH AI reference price fallback
MDF now places 3 levels of resting bids and asks per symbol each cycle,
ensuring order books always have liquidity. CH AI trader falls back to
securities.txt reference prices when books are empty. CH daily obligation
raised to 20.
