Your code is MT4. You are compiling with MT5.

I'm trying to code for MT5. I need help with MT5.  And my code is copyright free.

I have moved your topic into the MQL5 section: Expert Advisors and Automated Trading. However, please note that your code is not proper MQL5 and this has nothing to do with copyrights.

You probably generated using ChatGPT os some other generator, which mixes MQL4 and MQL5. If that is the case then we will not be able to help you because you seem not to realise the implications.

You have to check documentation of OrderSend and fix yourself, I just added some code so you can learn however this code is neither tested nor complied
