I have a strategy based on the average SMA, buying on average. How to add a condition of purchase: the opening of the candles in the average and closing above the average?

Maybe I'll ask for help again, but I will show you the problem. SMAStrategy.java strategy is. I want to add a condition to using buy: candle opening under sma10 and closing the sma10. If you sell it or vice versa. Who can help?

Hi,

You can try something like this in your onTick() function:

public void onTick(Instrument instrument, ITick tick) throws JFException {
        if (!instrument.equals(selectedInstrument)) {
            return;
        }
        IBar prevBar = history.getBar(instrument, selectedPeriod, OfferSide.BID, 1);
        IBar currBar  = history.getBar(instrument, selectedPeriod, OfferSide.BID, 0);
...
        if ( (currBar.getOpen() < filteredSma10)
        && ( (order == null) || (order.isLong() && order.getState().equals(IOrder.State.CLOSED)) )
           ) {
                print("Create SELL");
                order = engine.submitOrder(getLabel(instrument), instrument, OrderCommand.SELL, 0.01);
        }
