Dukascopy Support Board • View topic - discrepancy in output of RSI used as vector with one element and two elements

MikeD

Dear support,
I got discrepancy in output of indicator when using RSI on onBar method as

double[] rsiFA=indicators.rsi(Instrument.EURUSD, periodbar, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, period_RSI , Filter.ALL_FLATS, 2,bidBar.getTime() ,0);
//here rsiFA is a vector with 2 elements, for last completed bar and previous to it

and

double[] rsiFA_OneBarOnly=indicators.rsi(Instrument.EURUSD, periodbar, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, period_RSI, Filter.ALL_FLATS, 1,bidBar.getTime() ,0);
//here riFA_OneBarOnly is a vector wit 1 element for last completed bar

So rsiFA[1] must be equal to rsiFA_OneBarOnly[0] since these both are RSI indicator with the same parameters for the CLOSE price of last completed bar. But numbers are slightly different. What is my mistake?

Thank you in advance,
your client
