Overview
Where the chart's underlying data actually comes from and the settings that control how that raw feed is converted into candles.
What's covered
- Exchange/feed selection — every chart is built from a specific exchange or data feed connection; the same instrument can look different (different volume, different tick timing) depending on the source you're pulling from, and everything built on top of the chart — clusters, profiles, indicators — inherits that choice.
- Trade vs. quote data — some calculations, like clusters and footprint data, depend on individual trade prints rather than aggregated quotes; the data source setting determines whether that granularity is available.
- Historical backfill — controls how far back the platform will pull data when you first load a chart or increase the look-back period, which determines whether naked POCs and other levels that reference prior sessions have the history they need.
- Reconnection behavior — what happens to the chart's data stream when a connection is dropped, worth understanding before you rely on a chart during a fast-moving session.
