ChartsPod One-Second Charts: Trade Coverage and Loaded-History Limits

One-second bars show microstructure that one-minute bars hide. They are built from public trades, and how far back they go depends on what has been loaded.

Short answer

ChartsPod builds one-second bars from public trades. Use them for execution-level detail: how price moved through a level, how fast, and with what bursts of volume. Before relying on them, measure how much one-second history is loaded for your contract (scroll back to the first bar), note any gaps, and avoid indicators with long look-backs that exceed the loaded range. A bar with no trades in that second is not the same as a missing bar.

What one-second bars show

1-second vs 1-minute1-second vs 1-minute. Left, 1-second: Speed of moves through levels; Bursts and pauses; Short loaded history; Many empty seconds in quiet markets. Right, 1-minute: Cleaner structure; Longer history; Hides intrabar sequence; Fewer empty bars.1-SECONDSpeed of moves through levelsBursts and pausesShort loaded historyMany empty seconds in quiet markets1-MINUTECleaner structureLonger historyHides intrabar sequenceFewer empty bars

Control names in the terminal can change between releases. If a label differs from this guide, look for the setting that does the job described.

Good uses of one-second bars

Watching how price traverses a level: a clean move through with steady volume differs from a stuttering move with pauses and bursts.

Timing entries around a confirmed level, after the higher-timeframe decision is made.

Reviewing a fast event such as a liquidation cascade, where one-minute bars compress the sequence into a single candle.

Limits to keep in mind

One-second bars amplify noise. Indicators tuned for minute or hour charts behave very differently on seconds, and many signals will be meaningless. Use them mainly for reading price and volume directly, not for running long-period indicators.

Sources and methodology

ChartsPod capabilities were checked against its public overview, documentation index, markets and indicator pages on 17 October 2026. Exact control names inside the terminal can change between releases, so this guide describes what to set and check rather than quoting menu labels. Venue availability is shown per tool in the terminal. Worked examples use illustrative numbers. ChartsPod states one-second bars are built from public trades; loaded-history depth is not published, so this guide shows how to measure it.
