How would I code this to get around the error "Cannot use a mutable variable as an argument of the security function." Any help would be great. Thanks in advance
This script is version 4 and when converting to version 5, it gives other errors that I can't fix, thank you for your help.
And that I want to receive this code as an alert on 40 cryptocurrencies at the same time
