HOW IT WORKS
Order flow & positioning
Cumulative depth, taker aggression and trader cohorts, with price-level detail on demand.
Last reviewed November 2026
Order-book depth
A cumulative depth curve shows resting USDT notional on the best 20 bid and ask levels, using one shared price scale and one notional scale. A REST /fapi/v1/depth snapshot paints first; the partial depth20@100ms stream updates at most twice per second. The live indicator appears after the first valid streamed depth update. Disconnecting clears the stream book. Expand the price-level disclosure for the first 10 levels per side.
The ±0.5% imbalance meter and largest walls within ±2% use only the received top 20 levels. They are not a complete book. Resting orders can be cancelled; depth alone does not establish future price direction.
Aggression and cohorts
Taker buy/sell volume ratios use twelve 5-minute samples from /futures/data/takerlongshortRatio, drawn as a deviation chart scaled to the largest move in the window: a labelled 1.00 baseline with ratio gridlines, per-bar hover values with UTC time, the oldest-to-newest UTC range, and the latest ratio with its change versus the prior 5-minute sample. Above one draws upward for buyers; below one draws downward for sellers. The aggression, cohort and depth cards share equal height in one row.
Top trader accounts, top trader positions and global accounts use their corresponding long/short endpoints with period=5m, each shown with a percentage-ticked bar and both long and short shares, plus a top-positions-versus-all-accounts percentage-point divergence line computed from the same two readings. Cohorts and taker history refresh every 60 seconds; failed responses show unavailable. These are distinct populations and weightings, not competing buy/sell instructions.
