Liquidity, order books and liquidations

Identify what a heatmap measures, reconcile walls with trades, calculate slippage and evaluate sweeps without assuming a guaranteed reversal.

What you will practise

Turn a visible liquidity feature into a specific, falsifiable execution or market-structure question.

Before you start

  • Understand market versus limit orders and stop execution.
  • Know the difference between traded volume and open interest.

Course outline

  1. 1

    Distinguish order-book liquidity from liquidation heatmaps

    Separate resting orders, modelled liquidation levels and recorded forced closes. Read units, coverage and display settings before interpreting a bright band.

    8 min
  2. 2

    Track whether an order-book wall traded or disappeared

    Reconcile displayed depth with executed trades and net additions. Learn why a shrinking wall does not prove a fill, a spoof or a known trader's intent.

    8 min
  3. 3

    Calculate execution VWAP by walking order-book depth

    Fill a hypothetical market order across several price levels. Calculate average execution price, slippage in basis points and the effect of disappearing depth.

    8 min
  4. 4

    Evaluate a liquidation cascade without calling a bottom

    Separate forced-close evidence from a reversal hypothesis. Compare continuation and reclaim scenarios after price and open interest fall together.

    8 min
  5. 5

    Plan a liquidity sweep and reclaim as a testable setup

    Define the reference level, sweep, reclaim, invalidation and costs before entry. Compare a valid reclaim with continued acceptance beyond the level.

Educational material. Examples do not establish a profitable strategy. Trading costs, gaps and liquidation can produce losses beyond a planned stop.
