Why do the data of the regular mode and Deep history not match?

The choice of the time interval adds an additional input parameter for the strategy calculation. Because of this, the results of the calculation may change.

In the regular mode, the calculation is based on the bars loaded on the chart (the maximum number of bars depends on the TradingView subscription plan). In the Deep history mode, it uses all the bars that fall within the time period you have chosen for the calculation.
