Question about MA. Couldn't find it in the forum

[Forex Trader]

I was wondering how can I get the current value of the 90 day exponential MA?

Is it this:

test90 = iMA(NULL,PERIOD_H1,90,0,MODE_EMA,PRICE_MEDIAN,0);

? is it the right equation?

Most likely not because your time frame is H1, meaning that your bars are separated by 1 hour.
The shift is specified in bars.
So 90 bars would be sifting 90 hours from the current bar i=0
So you should multiply 90 by 24 or change time frame to D1

test90 = iMA(NULL,PERIOD_H1,90*24,0,MODE_EMA,PRICE_MEDIAN,0);
or
test90 = iMA(NULL,PERIOD_H1,0,0,MODE_EMA,PRICE_MEDIAN,90*24);
