A LONG-SHORT, SINGLE-INSTRUMENT, SINGLE-VENUE mean-reversion strategy on SOLUSDT.BINANCE USD-M whose signal is genuinely ORTHOGONAL to price: the aggressive TAKER buy/sell imbalance (taker_ratio feed, already collected in the supplementary set), NOT any indicator recomputed from the price series. Core microstructure insight — ABSORPTION. Aggressive taker orders cross the spread and should move price in their direction. When taker flow is extremely one-sided over a window YET price fails to travel with it (the aggressors are not being rewarded), it means informed PASSIVE liquidity is absorbing the entire flow. Once the crowd of aggressors is exhausted with nothing to show for it, price reverts AGAINST the direction of the aggression. So: extreme aggressive BUYING that price cannot follow → buyers absorbed → fade SHORT; extreme aggressive SELLING that price cannot break down → sellers absorbed → fade LONG. This is a divergence between ORDER FLOW and PRICE RESPONSE — mechanistically distinct from momentum/trend (which acts WITH flow) and from the liquidation/OI deleveraging fades already in the pipeline (which key off forced-exit feeds). Single venue + single instrument → the 1h bars and the taker_ratio feed are jointly available in the Layer-3 sandbox (no cross-venue/multi-leg verification risk; no options/IV dependency). Deliberately 2-parameter to resist the overfit deaths that dominate the log.
