Funding Chart

The chart is the centerpiece of ticker analysis. It displays historical funding rates (APR %) with a separate line for each exchange.

Core Elements

Exchange Lines

Each exchange is rendered in its own unique color. The line type is stepAfter — funding rates appear as staircase steps because the rate remains constant between settlement periods (every 1h or 8h depending on the exchange).

Toggle Buttons

Above the chart there is a button for each exchange. Click a button to:

• Hide that exchange's line from the chart
• Show a previously hidden line

This is particularly useful when the chart has many overlapping lines and you want to focus on specific exchanges.

Navigation

Y-Axis Zoom

Buttons for controlling the vertical axis scale:

• + — zoom in (narrow the Y-axis range)
• − — zoom out (widen the Y-axis range)
• R — reset zoom (return to the automatic scale)

By default the Y-axis is scaled to the 5th and 95th percentile of the data — extreme outliers are clipped so that the main picture remains readable.

Brush (Time Range Selection)

At the bottom of the chart there is a brush control — a draggable range selector. Drag its edges to:

• Zoom into a specific section of the chart
• Focus on particular days or hours
• Compare rates across different time windows

Tooltips

Hover over any point on the chart to see a tooltip with the exact funding rate values for each exchange at that moment in time.

How to Interpret

• Line above zero — longs pay shorts on this exchange (profitable to be short)
• Line below zero — shorts pay longs on this exchange (profitable to be long)
• Large distance between lines — high spread, strong arbitrage potential
• Parallel lines — the spread is stable over time (a positive sign)
• Crossing lines — the spread is unstable; rates are swapping positions
