I'm trying to submit a STOP buy order that has a stop loss specified but no slippage. However, I find that even when I make slippage = 0.00 the order turns into a LIMIT order before it is filled. The Wiki documentation says that if isNaN(slippage) == true that no slippage will be applied but when I specify 0/0 as the slippage parameter I get (as I would have expected) an arithmetic exception error when the order is submitted.

How can I program a STOP entry order that will not turn into a LIMIT order? I can get rid of the slippage manually but that takes away the usefulness of being able to automate the order.

See slippage description in javadocs of IEngine.submitOrder:
https://www.dukascopy.com/client/javadoc/com/dukascopy/api/IEngine.html#submitOrder(java.lang.String,%20com.dukascopy.api.Instrument,%20com.dukascopy.api.IEngine.OrderCommand,%20double,%20double,%20double)
Try:

    private IEngine engine;
    private IHistory history;
    
    @Override
    public void onStart(IContext context) throws JFException {
        engine = context.getEngine();
        history = context.getHistory();
        
        ITick tick = history.getLastTick(Instrument.EURUSD);
        try{
            engine.submitOrder("MyOrder", Instrument.EURUSD, OrderCommand.BUYSTOP, 0.01, tick.getBid() + 0.0005, Double.NaN);
        } catch (NumberFormatException e){
            //ignore, the NumberFormatException bug will get fixed with future releases
        }
    }
