Candles use the GE's average instant-buy (wick top) & instant-sell (wick bottom) per
period; bodies show period-to-period mid-price moves — the GE publishes no true open/close.

Each cell replays this item's history with that buy/sell percentile pair, no lookahead
(bands from past data only). ★ = best. Hover a cell for flips & hold time.

Bands are a starting point, not a promise — the fill model
is simplified and popular flips crowd (your buy gets bid up, your sell pushed down). How this works →
