Greetings, looking for some code

Hello,

I am looking for code that will let this script put on a trade; my understanding is that I need to account
For maximum, minimum and market info mode step in order for it to function correctly.

I am a learning coder, and any help is greatly appreciated, also thank you Coders Guru for this website which will help me learn to code.

Best regards Dale.

The Idea of the script is to use high [1] - low [1] to calculate lots, the account percentage risk is fixed at 1/4 percent.
