MAX and MIN errors

[Brevo]

Hello,

I am trying to get a max, min values over a period a time. I have private variables declared in the beginning of the class:

private double high;
private double low;

in OnBarUpdate(), I assigned them to MAX and MIN:

high = MAX(high,30)[0];
low = MIN(low,30)[0];

And I am getting these errors:

Cannot implicitly convert type 'NinjaTrader.NinjaScript.Indicators.MAX' to 'double'

when I check the documentation, I don't see anything different: https://ninjatrader.com/support/help...aximum_max.htm


How do I fix this?

Really? Nothing different?

Look again, carefully, C# is very case sensitive.

You've used high and low where you should be
using High and Low -- that one letter difference in
case is extremely important.

The fix is simple,

high = MAX(High,30)[0];
low = MIN(Low,30)[0];​

The first argument to MIN and MAX must be a data
series -- and high and low are not data series.

That is, the variables high and low are type double,
but High and Low are type Series<double>. The case
of the first letter makes a critical difference, because,
all C# identifiers (whether variables, types, or methods)
are all case sensitive. For ex, high, High, and HIGH
are three completely different identifiers.

Make sense?
