AQS charts

The Charts workspace displays market candles from a selected data feed. Use it to inspect prices interactively; use a research notebook when you need Rust calculations, historical snapshots or repeatable analysis.

Select the market

Open Charts, choose a saved data connection, enter the provider’s symbol and select a timeframe. Custom feeds show their display name with the provider so multiple connections can be distinguished.

The chart loads historical candles and subscribes to updates supported by that feed. Updates received while history is loading are merged with the historical bars. The displayed history is bounded to 5,000 candles.

Symbols and available history depend on the provider. Yahoo and an MT5 broker can use different names for the same underlying asset. CSV supplies historical bars, not a live quote stream.

Understand quotes and execution

A data feed provides market information; an execution broker handles orders. Selecting a chart connection does not change the feed or broker of a running strategy.

Synthetic quotes are not a real bid and ask spread. Check the feed’s capabilities before interpreting displayed prices as executable quotes. See Datafeeds for configuration and provider behaviour.

Charts inside research notebooks

Notebook charts are saved analysis outputs rather than live subscriptions. After loading data, use:

aqs_plot(&bars, "close")?;

This draws a line preview of a numeric column against its historical timestamps. It does not open a live chart or submit an order. See Research charts and helpers for indicators, table previews and custom output.
