How does Markov show a liquidity heatmap?
It shows where buyers and sellers have parked orders, so you can see the levels price has to trade through. On Markov the heatmap sits under the candles, from Hyperliquid's order book read live in your browser and recorded once a minute by Markov's collector. Paid plans see it on 1h and 4h charts (growing to 90 days from 14 Oct 2026).
