Most sentiment indicators restate the chart: price went up, so sentiment is bullish. This one measures something the chart cannot show — which side is actively paying to get filled, right now.
A trade needs two parties, but only one of them chose to trade at that moment. The aggressor crosses the spread and pays for immediacy; the other side was resting patiently on the order book. Summing aggressor volume shows which side is being forced through the book — information price alone does not carry.
Over a rolling 60 seconds, buy-side and sell-side aggressor volume are netted into one imbalance, then blended with the price movement that flow achieved — weighted 72% flow, 28% momentum. Pressure builds in the tape before it reaches price, so flow leads and momentum confirms. Heavy buying that moves nothing reads weaker than heavy buying that lifts the market.
The score is smoothed and mapped to five bands, from Heavy Distribution through Balanced to Strong Accumulation. Below twelve fills in the window the meter reports Calibrating rather than inventing a reading out of noise.
