How to specify MarketSeries date range?

Is there a way to specify the date range of a MarketSeries in a cBot?

For instance, I would like to return the open, high, low, and close prices, for the 1 minute bars, between two dates.

As an example, I would like to loop through all the minutes between say, the 1st Jan 2014, and the 1st Jan 2017, in order to get the open, high, low, and close price for each minute in that date range.

This would 'probably' run in the OnStart method, and the code could look like something along the following lines.

protected override void OnStart()
{
	// Specify date range.

	DateTime date_start = new DateTime(2014, 1, 1, 0, 0, 0);    // 1st Jan 2014, midnight.
	DateTime date_end   = new DateTime(2017, 1, 1, 0, 0, 0);    // 1st Jan 2017, midnight.

	MarketSeries = ...    // Set date range, somehow.

	// Loop through all 'bars' in MarketSeries.

	bar_count = MarketSeries.Close.Count;

	for ( int index = 0; index < bar_count ; index++ )
	{
		double open  = MarketSeries.Open  [ index ]
		double high  = MarketSeries.High  [ index ]
		double low   = MarketSeries.Low   [ index ]
		double close = MarketSeries.Close [ index ]

		// Do stuff with OHLC price data here.
	}
}
