I wrote the following code in the onBar() method to skip further processing if the trend is not going up:

double[] fastMA = JForexContext.getIndicators().ma(instrument, period, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, 40, IIndicators.MaType.SMA, Filter.ALL_FLATS, 2, barTime, 0);

double[] slowMA = JForexContext.getIndicators().ma(instrument, period, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, 80, IIndicators.MaType.SMA, Filter.ALL_FLATS, 2, barTime, 0);

if (fastMA[0] < slowMA[0]) return;

In theory, there should be no trade if fastMA is below slowMA. However during backtesting, I saw several trades under this condition. Am I doing something wrong in the code, or is the MA calculation not working properly in backtesting?

Thanks,

Vinh

Make sure you use the right platform filter (Filter.ALL_FLATS since you use it when calling indicators).

I found out that I forgot to filter out the irrelevant periods. It works now. Thanks.
