variable in onexecution

[tonynt]

Hello,

when I use in the onexecutionsection a variable like

if (exitOrder1a != null && exitOrder1a == execution.Order&& execution.Order.OrderState == OrderState.Filled)
{
if(stopstep ==1) then do
if(stopstep==2) then do

(also when I do if (stopstep!= null && stopstep ==1) then do )

there appears in the output window the errormessage "error onexecution.. object reference not set to an instance"

When I do without the variables then there is no error-message in my script.

Can´t I use a variable in this section? Or how can I use it without causing error?

Thanks
Tony

You can use variables in this section and it sounds like you understand checking for null before proceeding is the correct action.

I'm not seeing any apparent error with the code here. Where is stopstep defined in your code?

I would begin by adding various Print() statements to your OnExecution() to ensure you correctly identify the cause of this error.

Hello,

thank you for your reply. I have defined my "stopstep" in the variables section with double stopstep = 0;

This I do for counting inside the script-strategy. Every time the stops are changed this counts +1, so that I always know in which "part of the strategy or trade something occurs" and also this way I can touch it as a condition like I want to do here in onexecution.

Best

If you'd like you can post a simplified version of the code that replicates the error and I'll see if I can spot something.
