There may be a SELL order (StopLoss/Target) already in the system.

@s565246 Hey there,

I suggest you to print all your environment variables.

After printing you should get your credentials. Check those credentials especially username.

FYI, if there is any value stored in variable named "username" (ignore the case sensitivity) , the environment variable references it as username (this is somewhere used in your pc already) , which usually it is "admin".

@prasannkoli16 , Hey there!
Are you perhaps using environment variable to store your api key , client id and topt ?
