how to write the code when submitting an short order if i want to set SL to high band of emaEnvelope indicator of current candle

since SL should be double and emaEnvelope returns an array of double,if i just use
SL_ema_10mins_B=indicators.emaEnvelope(instrument,Period.TEN_MINS,OfferSide.BID,AppliedPrice.CLOSE, 5, 0.1,indicatorFilter, 2, prevBar1.getTime(), 2);
order = engine.submitOrder(getLabel(instrument), instrument, OrderCommand.SELL, amount,currentAsk,slip,SL_ema_10mins_B[0][0],0);

there will be java.lang.ArrayIndexOutOfBoundsException,how to deal with that?

ok i can use double []emaEnvelope to set SL,but how to use double[][] emaEnvelope?

and what are double[][] emaEnvelope outputs?

Hi,
If you want to set an order stop loss price to the current candle ema envelope high band value please use the following code:

double [] currentEmaEnvelope = indicators.emaEnvelope(instrument, Period.TEN_MINS, OfferSide.BID, AppliedPrice.CLOSE, 5, 0.1, 0);
order = engine.submitOrder(getLabel(instrument), instrument, OrderCommand.SELL, amount,currentAsk,slip,currentEmaEnvelope[1] ,0);

When you need to get ema envelope indicator values with specified filter or you need to get the indicator values for several candles you have to use double[][] emaEnvelope. For example to get ema envelope values for last 3 candles you can use the following code:

double [][] ema_10 = indicators.emaEnvelope(instrument, Period.TEN_MINS, OfferSide.BID, AppliedPrice.CLOSE, 5, 0.1, Filter.NO_FILTER, 3, prevBar.getTime(), 0);

The ema_10[0][0] contains the 3rd candle lower band value, the ema_10[0][2] contains the last candle lower band value, ema_10[1][2] value contains the last candle upper band value

For additional information how to use indicators from a strategy, please take a look at the following JForex Wiki page: https://www.dukascopy.com/wiki/index.php ... Indicators
