Strategy: Days to Load/Start Date

[bigsurftrader]

Hi -

Is there a way to set -- within the code -- the "start date" for the days to load?

For example, let's say I want to set "2/2/2015" in the code. Is there a way to do this?

Thanks!

Hello bigsurftrader,

Thanks for writing in.

As the days to load is intended for input by the end user in the GUI, there is not a way to force the days to load in the primary data series of an indicator or a strategy. You may however add a return condition to prevent your indicator or strategy from processing historical data from before that period of time.

The following example will not process anything in OnBarUpdate() if a) there are not enough bars, and b) The date of the bars are before 02/02/2017. A message will also be displayed when from OnBarUpdate() method before it gets returned.

protected override void OnBarUpdate()
{
	if (CurrentBars[0] < 1)
	  return;

	// Return if the bar date is before 02/02/2017
	if (Times[0][0] == new DateTime(2017, 2, 2))
	{
	  Draw.TextFixed(this, @"ReturnMessage", @"Bars taking place before 02/02/2017", TextPosition.TopRight);
          return;
	}
			
}

Usage for the Times series and DateTime can be referenced below. I will also link the documentation for Draw.TextFixed():

Please let me know if you have any further questions.
