I am trying to write a code that will able to find the lowest of the last X swing lows and the highest of the X swing lows by using the Swing indicator in Ninjatrader.

This is how I did it

MIN(Swing(BarsArray[1], 1).SwingLow, X)[0];

MAX(Swing(BarsArray[1], 1).SwingHigh, X)[0];

For some reason it does seem to be working. My impression is these functions find the highest swing high of the the last X days and not the highest of the last X swing highs (which may be useful too but it is not what I am looking for).

I have been told that I need to use ArrayLists but I have not idea how to go about it; it goes beyond my programming skills and I found nothing on Ninjascript. Can anybody help please?

Hi,

My quick impression, if the approach is valid (didn't spend the time), is the problem might be the BarsArray[1]. Try BarsArray[0] here to see if it does what you expect. I think you need to have a multi-series strategy/indicator to us [1].

Hope that helps.

Sorry I did not explain why I have BarsArray[1] in the indicator. The reason is just that I am working on multi time frame and I created a BarsArray of daily bars in Initialize section

Add(PeriodType.Day,1);

That has nothing to do with what I am looking for; the code could easily be

MIN(Swing(1).SwingLow, X)[0];

MAX(Swing(1).SwingHigh, X)[0];

Sorry about the confusion

Okay,

I think Swing might have "missing values". I don't know if MIN/MAX ignore these values. YOu might need to scan the array yourself with a for/next loop and ignore missing values.
