Checking indicator result in X number of bars back

[Domek_69]

Hi,
I would like to check whether an indicator met certain criteria any given day within the past X bars.

For example: If Highest High for 500 days was met any day in the past 10 days, than do something...

I know I can use MAX() for HighestHigh. But I am not sure how to handle those 10 days. Is there any simple way? Should I use some kind of LOOP for it?

Some kind of:
For n from 1 to 10
if Close [1 to n] > MAX(Close, 500) then
...

Thank you

Petr

Hello Domek_69,
Thanks for your post.

You could use a loop. In some cases that is the only way to go about something like this. In the case of your example however, I might start with something like the following to check if a bar in the last 10 is the highest in the past 500. You could expand on this in multiple different ways.

private double last500bars;
protected override void OnBarUpdate()
{
    if(CurrentBar<500) return;

    last500bars = MAX(Close,500)[0];

    for( int i=0; i<10 ; i++ )
    {
        if( High[i] >= last500bars )
        {
            //Do something
        }
    }    
}
