What it means

For AAPL on the session of 2026-10-30: True now: Above its 20-day volume-weighted price; Is the stock above its 50-day moving average. On the line: Is the 14-day ATR less than 2% of the price. Forecasts: Volatility rising over 5 days 61%; Up tomorrow 56%. Fired: aggressive (Webhook → ems).

A trending stock with good next-day odds goes to a participation algo; otherwise the order is spread over the day with VWAP.

What it means

For XLE on the session of 2026-10-30: True now: Swings less than half their 50-day size. Not true: Is today an NR7 day, the narrowest range of the last 7 sessions; Is Bollinger Band width at its lowest in 120 sessions. Forecasts: A big move either way in 5 days 40%; A 2%+ move either way in 5 days 36%.

Compression after a narrow day often precedes expansion; the forecast quantifies how likely a big move is, not its direction.
