I try to use the rsi indicator within a strategy by the call

double rsiOut = indicators.rsi(instrument, Period.DAILY, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, TIME_PERIOD_RSI, 0);

with TIME_PERIOD_RSI = 8.
The output of these rsi values on the console by

console.getOut().println(date.toString() + ": rsi = " + rsiOut);

shows a massive (!) difference to the values I measure from the RSI chart (close price, daily and TimePeriod = 8) within the instrument chart.
Why? What's the mistake?

Modifying the shift or TIME_PERIOD_RSI in the indicators.rsi call does not show any improvement.
On the screenshot "tester_output.png" it's obvious that there's a large descrepancy on 20th April from the rsi output and the rsi chart.
I suppose it's a trivial mistake I am making but cannot find a solution.

Many thanks in advance!
Best regards.

Hi,
if you are executing an indicator like you show, then it means that:

• The indicator is calculated from all type of candles (including all flats)
• The indicator is calculated starting from current incomplete candle (shift = 0)

These two are the main points why are you not getting same values as charts has.
First of all you need to configure your chart preferences. Open Tools->Preferences->Chart. Find section "Flats Filtration". Select option "Flats filter is disabled". And the second thing is as a first candle use the first completed bar (Shift = 1).
Please consider this code:

    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
        if (Instrument.EURUSD == instrument && Period.DAILY == period ){
            double rsi = context.getIndicators().rsi(instrument, period, OfferSide.BID, AppliedPrice.CLOSE, 8, 1);
            context.getConsole().getOut().println(new Date(context.getHistory().getBar(instrument, period, OfferSide.BID, 1).getTime())
                +"    rsi= "+rsi);
        }
    }

What is the other way around?
I mean, how to mantain the Filters active on charts and still have the same output in the code?
I have a custom indicator and I'm pretty satisfied of how it displays on chart. Now I'd like to use the same values within a IStrategy.
Kind regards,
Paolo

If you use filter ALL_FLATS in the chart, you can call rsi indicator with filter from the API in you code:

double[] rsi = indicators.rsi(instrument, period, OfferSide.BID, appliedPrice, timePeriod, Filter.ALL_FLATS, numberOfCandlesBefore, prevBar.getTime(), numberOfCandlesAfter);
