Hi, I need a little help.. Currently I'm using this code for my ''shifted ema'' : EMA = indicators.ema(Instrument.instrument, Period, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, Period, 1) I want to add a filter to remove the flats.... I can't find the appropriate code to do so... How can I solve this ??? Thx in advance for help

Hi, Please have a look at the following code: long prevBarTime = context.getHistory().getBar(Instrument.EURUSD, Period.THIRTY_MINS, OfferSide.BID, 1).getTime();
double[] filteredEMA = context.getIndicators().ema(Instrument.EURUSD, Period.THIRTY_MINS, OfferSide.BID, AppliedPrice.CLOSE, 50, Filter.ALL_FLATS, 1, prevBarTime, 0);
console.getOut().println(filteredEMA[0]);

Thank You for a super fast answer, I was missing this parts context.getHistory().getBar and context.getIndicators().ema.. Thank You again
