Interface IHeatmapHistoricalDataLoadedConsumer

Namespace

ATAS.Indicators.Heatmap

Assembly

ATAS.Indicators.dll

Optional capability: receive a notification when the host's working data range expanded backward (e.g. user panned into history that triggered a load). Implement only if the indicator needs to rebuild or refill calculation state across newly-loaded historical samples. Typical reaction: take a lease, Clear(), refill from new historical range, dispose lease — the front stays visible across the rebuild.

Added in ATAS 8.0.15.

Methods

OnHistoricalDataLoadedAsync(HeatmapWorkingRangeUpdate, CancellationToken)

Notifies the indicator that the heatmap has loaded historical data and its working range now starts at NewDataStartTimeNanos. Called on the instance's own task, serialised with the other callbacks, for hidden instances as well as visible ones.

Parameters

update HeatmapWorkingRangeUpdate

The previous and new bounds of the working data range.

cancellationToken CancellationToken

Cancelled when the per-call timeout expires or the instance is shut down.

Returns
