Methodology
How to read a footprint chart: context, confirmation and invalidation
Read a footprint in four passes. Start with a level that mattered before the current bar. Then inspect the executed volume at that level, not the largest number anywhere in the candle. Require the next price action to confirm the reading, and define the price that proves the idea wrong before acting. A footprint is evidence from completed trades, not a trade signal by itself.

Start with a question price has already asked
A large imbalance in the middle of a quiet range can be ordinary noise. The same reading at a prior session high, a volume-profile edge or the return to a broken level has a specific question behind it: did aggressive trading move price through the level, or did it meet enough passive liquidity to stop?
Mark the level before opening the footprint. That prevents the usual mistake of finding a colourful cell after the move and treating it as a reason that was available before the move.
Read the trade that happened, not the story around it
Bid × ask is executed volume split by the side that crossed the spread. A stacked imbalance says aggressors traded through several price levels. Absorption says unusually heavy two-sided trade occurred with little immediate progress. Neither statement names a buyer, seller or future direction.
- Ask whether volume was one-sided or balanced.
- Compare the cell with neighbouring cells and recent bars, not a universal “large” number.
- Keep cell height and imbalance settings visible in the review; changing either changes the picture.
Let price answer the footprint reading
An absorption marker at resistance becomes a working short hypothesis only if price fails to hold above that resistance or returns below it. A buy stack becomes a continuation hypothesis only if price accepts above the stacked zone. The next bar is not a formality: it distinguishes a reading from an interpretation.
Write the condition that ends the idea first
For a defended level, invalidation is acceptance through the level, not a second marker of the opposite colour. For a continuation idea, it is failure to hold above the zone that supposedly showed aggressive acceptance. The exact distance and risk belong to the trader’s plan; the page supplies no target or return claim.
