N day high

Greetings,

How can I determine if yesterday's close price is the rolling 50 day high? This is what I tried so far

Code


vars Prices = series(priceClose())
var Max50Day = MaxVal(series(priceClose()+1),50);

if (equalF(Max50Day, Prices[1]))
{
    // do stuff
    printf("\n%f %f %f",Max50Day, Prices[1], equalF(Max50Day, Prices[1]));
}

When I run this, I'm entering the IF statement on every iteration even though equalF(Max50Day, Prices[1]) evaluates to 0.000.

I've also tried the following in the IF expression

Code

if (Prices[1] >= Max50Day)

Which only matches once in 16 years worth of SPY daily close history (?).
