Hallo,
i have a question about the TakeProfit/StopLoss accuracy when submitting an Order with:

submitOrder(patternID, instrument, command, 0.01, 0, 0,history.getLastTick(instrument).getBid() - SL * instrument.getPipValue(), history.getLastTick(instrument).getBid() + TP * instrument.getPipValue()) ;

As illustrated in the picture, sometimes the Take Profit is missed although the a Tick would have validated the Filling.
(Small horizontal lines represent the Take Profit target - in the first case the StopLoss is hit, second shows proper behaviour)



Would it increase the likelyhood to be properly executed if i manually check the ticks in onTick()?

Hope i made myself clear -

greetings and thanks in advance!

What do you mean by "missed"? In the given picture the take profit apparently was fired on the very candle which hit the price level that you have drawn on the chart.
Of course if you want to make sure for yourself that take profit works correctly, you can do this by double-checking the prices in the onTick.

For me the first order is closed on SL, and not on TP.
Why:
Although it seems that the candle's low is way below the TP level, there is no guarantee that the candle's high haven't reached the SL level sooner. And that is happened here (current price went above SL level before order could have been closed on TP).

There is no need to check current price against an order's TP and SL levels in the onTick() function to have properly executed TP and SL levels. If you submit an order with SL/TP (or add/modify them later), the system will close it at those levels.

Thanks to both of you - i looked into the actual ticks and indeed for all the cases it simply was the case that the tick reaching the TP was later in time - (just a coincidence that this happened +20 times in a period of 1 month )
