What Im trying to do is to find software that would allow me to write my own indicators and automate trade, execute orders on Bybit. Or I make my own software using the Bybit APIs, best solution maybe.
Crypto Traders use trading bots to automate their tasks, try looking into them and see if some stuff you're looking for are possible with them. Just don't forget to set your bybit API key in a way where it's not possible to withdraw your funds with it to minimize additional exposure risk.
For starters, you can start on this thread, see:
