get the high / low price for a period

The following business logic should help with finding it on say a M1 chart:

1) get the index of the open time of the bar when the position was opened. Ex: Bars.OpenTimes.GetIndexByTime(position open time);

2) get the index of the bar in which the position was closed. Ex: Bars.OpenTimes.GetIndexByTime(position close time);

3) loop from start to finish, checking the high and low of every bar in between the open and close time indexes you obtained in steps 1 and 2 above

thanl you very much, @firemyst, for your kind reply.

can you or the cTrader support team help me to understand, how I can implement this or a similar logic for m1 into a Renko cBot?

Kindest regards and a great and successful week,

I do not use Renko charts, so won't be able to help you there.

Hi,

Try this:

        private double GetMax(DateTime startTime, DateTime endTime)
        {
            var startBarIndex = Bars.OpenTimes.GetIndexByTime(startTime);
            var endBarIndex = Bars.OpenTimes.GetIndexByTime(endTime);

            var max = double.MinValue;

            for (var barIndex = startBarIndex; barIndex <= endBarIndex; barIndex++)
            {
                max = Math.Max(Bars.HighPrices[barIndex], max);
            }

            return max;
        }

        private double GetMin(DateTime startTime, DateTime endTime)
        {
            var startBarIndex = Bars.OpenTimes.GetIndexByTime(startTime);
            var endBarIndex = Bars.OpenTimes.GetIndexByTime(endTime);

            var min = double.MaxValue;

            for (var barIndex = startBarIndex; barIndex <= endBarIndex; barIndex++)
            {
                min = Math.Min(Bars.LowPrices[barIndex], min);
            }

            return min;
        }

This should work on all chart types as long as the data is available on your chart in between start and end time.

Dear amusleh,

thank you for your kind support with my question and the code you have provided!

I have implemented it into my cBot and will run it - in my test it works as wanted.

Again, great support and great community here - appreciate it a lot!

Kindest regards to you and Panagiotis
