    Custom indicator in strategy - error onbarupdate

    Hello,
    I have only basic programming skills, but browsing the online manual i found a way to measure the slope angle of a indicator (EMA). Its only one row of code and when i run it on any chart it works fine, i can see the digits in the Output. However when i try to include it in a strategy (which also works fine standalone) i receive error:

    "Strategy 'GameOverTest': Error on calling 'OnBarUpdate' method on bar 16: Index was outside the bounds of the array."

    I guess this is happening, because when i run the indicator alone it will calculate and return in the Output window a lot of digits (i can presume it calculates everything from the beginnig of the chart). I dont need this, i only need the last digit. How can i achieve this?

    The indicator:

    double angle = (Math.Atan(Slope(EMA(25), 5, 0))*18000/Math.PI);
    Print (angle);

    Best regards,
    Hristo

    Hello Hristo,

    Thanks for opening the thread.

    I am noticing the same behavior on my end when calling an indicator that contains an indicator from a strategy.

    I will be looking into this further and will provide a complete answer of my findings.

    EDIT:

    Upon further investigation, it looks like the indicator being called is creating an issue because it is not setting a plot value. You can work around this issue by adding a plot and setting its value to something.

    Attached is an example strategy for demonstration.

    Thanks in advance for your patience.
