Get largest val from array of plots

[bernie_c]

I have an array of plots:

protected override void Initialize()
{
int i;
    for( i=0; i < kPlots_total;  i++ )    
        Add( new Plot( short_up_color, PlotStyle.Line, "Plot" + i.ToString() ) );
} 

I plot most recent close:

protected override void OnBarUpdate()
{
int i;
    
    for( i=0; i < kPlots_total; i++)
        Values[i].Set( EMA( Close, periods[i] )[0] );
} 

All this works fine. I would like to know the min and max values that I just plotted. I was hoping MAX() would work, but according to the documentation it only works with iDataSeries not arrays of iDataSeries. Am I missing something? It is not a problem to loop through and find the min and max in code. Just wanted to use existing functionality where possible.

Hi bernie_c,

When calling MAX() pass the dataseries, not the entire array of dataseries.

i.e. MAX(Values[1], 20)[0]

Values is the array of data series. Values[1] is the second dataseries object.

I don't want the largest value in a range of a single dataseries. I want to look at all the dataseries in the array and find the one with the largest value in the 0 barsAgo position. This largest value is what I am after.

Hello bernie_c,

You will need to make a custom loop to do this. There is not a method in C# that does this that I know of.

For example:

double largest = 0;
for (int i = 0; i<BarsArray.Count-1; i++)
{
if (Closes[i][0] > largest)
largest = Closes[i][0];
}
