MIN and MAX functions

[Ray11]

I'm trying to get the minimum and maximum of two values in the script, but it seems like MIN and MAX function don't work properly or are the wrong functions. Does anyone have a resolution?

Here is the part of code I cant get to work:
else if (State == State.DataLoaded)
{
bollinger = Bollinger(2, 20);
}


protected override void OnBarUpdate()
{
if(CurrentBar < 2) return;
double upperValue = bollinger.Upper[1];
double lowerValue = bollinger.Lower[1];

double _HigherBand = MAX(upperValue,2)[0];// I need to identify the highest BB Upper band of the last two candles from previous close (close[1] and close[2]
double _LowerBand= MIN(lowerValue,2)[0];
}

Hello Ray11,

Thanks for your post.

MIN() could be used to get the lowest value over a specific period. MAX() could be used to get the highest value over a specific period.

Calling bollinger.Upper[1] and bollinger.Lower[1] returns a double value.

MIN() and MAX() requires that you pass in a Series<double> value and an int argument to specify the period.

MIN(int period)
MIN(ISeries<double> input, int period)

MAX(int period)
MAX(ISeries<double> input, int period)

See the help guide documentation below for information about MIN() and MAX() as well as sample code.

Please let me know if I may assist you further.
