How to read orderbook delta
Green bars are buy walls
Aggressive bid depth: big buyers placing limit orders below price. It acts as support, so it is harder for price to drop through.
Red bars are sell walls
Aggressive ask depth: big sellers placing limit orders above price. It acts as resistance, so it is harder for price to break through.
Delta direction
When green dominates, buy pressure is building. When red dominates, sell pressure is building. Watch for sudden shifts.
Spoofing warning
Large walls that appear and disappear quickly are often spoof orders meant to manipulate. Check whether a wall persists across several snapshots.
