once downloaded a bot from github and fixed it a bit. The bot tried first to buy and sell with some restrictions on price and percentage. To be honest, the risk is big, but it was worth it (I made $468 from $50 in a month) But writing interactions from scratch and the bot is not smart enough.
So basically you've managed to edit and run it on your own? What kind of features are you looking for that you are looking for in a script-based trading bot? I suggest making a new thread on services if you want to commission someone to edit or make a bot for you. There is no way you can find a free one that is designed specifically for your purpose. Even if you do, there will always be some restrictions like limited API calls and so on.
I was able to make the changes using GPT chat. The bot traded on the txbit exchange, but it closed. On the txbit exchange, many coins had a large price difference compared to popular exchanges. People upload to Github for free to many but popular exchanges.
