Order Flow
Footprint / Delta Charts
Price making a new high doesn't say who paid up to get there. A delta panel underneath every candle tracks net buying against net selling, the layer price alone can't show.
Guess blind, then look at the delta panel
The tape streams in price-only. Every time it prints a fresh swing high above the last one, it pauses and asks you to guess whether the delta behind that new high confirms it, more net buying than the prior swing, or diverges, less net buying despite the higher price. Guess first, then the delta panel reveals the real numbers, and a few bars later you find out whether it actually mattered.

How it works
- Delta is net buying minus net selling for that single bar. A positive bar means more volume traded on the buy side than the sell side, negative means the reverse, regardless of which way the candle's body points.
- A new swing high only counts once it clears the last one by a real margin. This page tracks the most recent local high and compares each fresh one against it, not against every prior bar.
- Confirms means the new high traded with more net buying than the last swing high did. Diverges means the opposite, a higher price print backed by weaker or negative delta.
- Rollover is checked a fixed 5 bars later, against the swing's own low. A close back below that low counts as rolling over, anything else counts as holding.
- Guessing from price alone is close to a coin flip on purpose. That's the entire point of the panel being hidden first, price shape here carries almost no information about what the delta is actually doing underneath it.
Where this breaks
This delta is simulated, real delta comes from an actual order book
On a real footprint or delta chart, that number comes from matching every executed trade to the bid or the ask at the moment it filled, a real record of who was aggressive. The delta on this page is a randomized number loosely nudged toward each candle's own color, useful for practicing the reading skill, the comparison between two swing highs and the discipline of checking price against volume instead of price alone, but it is not derived from any real order flow. A genuine divergence on a real chart can also get overridden by a single large resting order, a fast news catalyst, or thin after-hours liquidity, none of which a clean two-number comparison like this one can represent.
