How can I debug this code?

[Chukwudozie Thankgod]

I am new to programming, I wrote this program to place buystops and modify them at intervals if not triggered or close them after some time if triggered. Who can help me get it working?

Chukwudozie Thankgod:

This code contains dozens of errors - the first thing to do is use the compiler and fix all the syntax errors.

It helps if you compile regularly while typing to avoid ending up with a large number of errors at the end, as we see here.

I suggest you comment out sections of code so you can handle this in a bite-sized manner - all part of the journey in learning how to program
