Math.Max

[tonynt]

Hello,


I only find in forum and help guide how to get the max or min of 2 values. But this doesnt work when I want to get the max or min of eg 5 values like
MaxN=Math.Max(value1, value2, value3, value4 value5);


Where do I get the solution for this please? Where is this in the helpguide?


Thank you!
Tony

Hello tonynt,

Thanks for the post.

The Max function will always take two args. You would nest them together to get the max of multiple numbers:

Math.Max(value1, Math.Max(value2, Math.Max(value3, (Math.Max(value4, value5)))));

Please let me know if I may help further.

Hello,


thank you for your reply. OK, I wrote math.max. It can be another function, dont need to be the math.max. What if there are more values to check?


Thank you!

Hello Tony,

Thanks for the reply.

If you needed to take the maximum of multiple numbers in this way, then you would need to do some kind of recursive formula that takes a list. Do this at your own risk though, because recursive functions are not supported in NinjaScript. The supported way would be to evaluate them in a nest like in my previous post.

Here is a publicly available example of a recursive max function that takes a list:

Please let us know if we may be of any further assistance.

See here for information about "params" keyword.

I typed up a quick method that should work (not tested).

public double MaxOf(double arg1, params double[] args)
{
    double retval = arg1;

    foreach (double item in args)
    {
        if (item > retval)
            retval = item;
    }

    return retval;
}

Use it like this,

MaxN=MaxOf(value1, value2, value3, value4, value5);

Hello tonynt,

Thanks for the follow up.

Can you send an email to us with your regular email and not through Help>Email support? If you can, restart your PC and test NinjaTrader's mail service again. You might need to test it on a different PC or a different network if possible. You might want to test to see if that happens with NinjaTrader 8 as well.

Please let me know if I may be of any further assistance.
