HOW TO FIND AND SETUP A BOT TRADER

Hello everyone,

Happy new year and lot of success for 21 !

I’m pretty new in the trading world (software, exchanges, API etc…) and I would like to discuss about how to setup a bot trader.

I’ve started to do some trades on coinbase and binance, and I want to automatize some orders.

I did some search and finded: FREQ TRADE. An open source bot.
https://www.freqtrade.io/en/latest/configuration/

So, I would like to know if this tool is trustable and what are the good and bad points ?

If trustable, what are the best hardware & software config to use and setup a bot: (CPU GPU Linux Windows etc..) ?

Basically, I just want a bot who is able to buy at a specific price and sell to another price (higher of course  

If you already know some topics or forums explaining how to setup a open source bot trader; let me please know  

Thank you in advance
