trading.bot

I have a problem that I want to solve with the bot, which is to have the bot buy and sell at the same candle price at the intersection of the two lines in the strategy, as well as the Python code, as well as the programmer who programmed the Python code.
I want someone who has a lot of experience in this field and is able to solve the problem.

The one who can solve the problem sends me a message so I can send him the details
Thanks
