Error on changeOrder Method

[kantkant2]

Hi,

I have this condition to change stoploss :

if (Position.MarketPosition == MarketPosition.Long 
&& enableShort == false)
{
if (stopOrderLong != null && stopOrderLong.StopPrice != (Position.AvgPrice - (stop * TickSize)))
{
ChangeOrder(stopOrderLong, 1, 0, (Position.AvgPrice - (stop * TickSize)));
}
}

it seems correct as syntax, but when I activate the system at each bar it always changes the order at the same price. Here an example from output window. OutputSample.txt can someone help me??
Thanks in advance

Hi, thanks for your post.

It looks like the ChangeOrder line is being called multiple times even though the price is still the same. Have you attempted using Print statements to see what kind of values your variables have? This is always the go-to for debugging. I solve 99% of the bugs I get with Prints.

Our colleague Chelsea has an example using the unmanaged approach and ChangeOrder here (third script down):

I look forward to hearing of your results.

fyi,
those examples don't use ChangeOrder -- they are for NT8 and use SubmitOrderUnmanaged.

Thanks Chris,
sorry but in this case the only variable called is "enableshort" and it is for sure = false, just checked...
if I remember well, I've read somewhere in the past that there was issues using for example "4*TickSize" instead "7 * (TickSize / 2)" because potential precisions with the doubles. Is that true and could be the case?

thanks

Precision can be corrected by Instrument.MasterInstrument.Round2TickSize(4*TickS ize).
