Callout Variants
Note — general information or context the reader should be aware of.
Tip — a useful technique or best practice.
Important — something critical the reader must not miss.
Warning — potential pitfall or common mistake to avoid.
Key Takeaway
- Volume confirms price moves — high volume = conviction, low volume = doubt
- Always check delta before entering a trade
- Footprint charts reveal what candlesticks hide
Before / After Slider

Volume Profile
Volume Profile shows the distribution of traded volume at each price level over a chosen period. It reveals where the market spent the most time (Point of Control) and key support/resistance zones.
Footprint Builder
Interactive step-by-step footprint construction from raw ticks:
Cluster Chart
Cluster chart showing multiple bars with bid/ask butterfly histogram and candle highlights:
Matching Engine
Step-by-step matching engine simulator showing how a market order consumes liquidity from the order book, generates prints (trades), and builds a footprint. Three synchronized panels update together on each step:
Market BUY 15 — eats through the first three ask levels
Next: Market BUY 15
Order Book
Time & Sales
Footprint
CVD Chart
Dual-pane chart: price candlesticks on top, CVD (Cumulative Volume Delta) candlesticks on the bottom. Trend lines show convergence/divergence between price and CVD:
Combining Components
You can mix shortcodes with regular Markdown freely:
Before reading the footprint, make sure you understand bid vs ask. Bid = volume traded at the bid price (sellers), Ask = volume traded at the ask price (buyers).
Then try the interactive builder above to see how each tick fills the footprint grid.
- Green (Ask) volume on the right, Red (Bid) volume on the left
- Delta = Ask − Bid for each price level
- Positive total delta = more aggressive buyers
