Hi,

I am using:

double[] ema = indicators.ema(myInstrument, Period.ONE_HOUR, OfferSide.BID, AppliedPrice.CLOSE, emaPeriod8, Filter.ALL_FLATS, candlesBefore, currBarTime, candlesAfter);

In other words there is no "to" parameter in this version.

I get an error message that says:

14:00:00 com.dukascopy.api.JFException: "to" parameter can't be greater than time of the last formed bar for this instrument @ jforex.EMAwithParams.testCandleInterval(EMAwithParams.java:95)

Repeat, there is no "to" parameter in this version. This problem has never occurred in the Historical Tester, only in the Live account version of JForex.

Can you help?

Do you call the indicator on a subscribed instrument? Can you replicate the behaviour with a trivial strategy (the one which does nothing but calling the ema indicator). In such case please post the example strategy and the list of instruments that you have opened in the platform.

Many thanks for coming back so fast. I have resolved the problem by replacing 0 with 1 as the Shift parameter in the line:

long currBarTime = history.getBar(myInstrument, Period.ONE_HOUR, OfferSide.BID, 1).getTime();

which was used to get the currBarTime parameter for the indicators.ema routine. This gives the last completed bar rather than the current bar. This works OK for my strategy and I can understand the logic of the indicators.ema routine rejecting a bar that is not yet fully formed, as a parameter.

Thanks again for your quick response.
