buy and sell orders

[snoppss]

Hi,
I have a big problem programing with NT a strategy. The strategy crashes each time I enable it. The questions I have is what exactly happens when I have multiple buy orders and then I submit a sell order.
In the other way, I don't understand how to read the log file: I don't know how to detect the problem with my orders and why it is rejected.

Thank you in advance,
R.E.

Hello snoppss,

Are the multiple buy orders working or filled?

What is the error message you are getting? Is the order rejected due to price, or overfill, or something else?

When you have working buy orders such as limit orders that have not filled, and an entry order to go short is placed, this order will be ignored.

If you are in a long position and an entry order to go short is placed, your position will flip from long to short.
