Realtime-History Matching

Understanding Realtime-history matching option

Realtime-history matching option allows MultiCharts to synchronize the calculation of studies based on several data series. When using several data series calculation on historical data may differ from real-time calculation Realtime-history matching option makes historical calculation results closer to real-time.

When Realtime-history matching option is enabled the signal/indicator is calculated on the latest bar of the main data series and on the currently completed bar of the auxiliary data series. If the auxiliary data series stops updating, the final calculation will be made on the main data series bar that was received immediately after the latest bar of the auxiliary data series. In this case no further calculation will be performed.

Note: If more than one auxiliary data series is used, the latest bar for the calculation will be the one that was completed earlier.

When Realtime-history matching option is disabled the signal/indicator is calculated on the basis of the main data series latest bar and current (completed or not) bar of the auxiliary data series. If the auxiliary data series stops updating, the calculation will continue on the basis of the latest bar of the main data series and the open bar of the auxiliary data series.
