The Automated systems which I have made for Crypto are very simple Moving Average cross entries and trailing stops.
I am Bearish on Bitcoin so I have my algorithms set to 'Short Only' mode and what they will do is short every time the rules I have created happen.
There is rules for when to enter trades and just as many rules for when not to enter trades as you can see from this picture it is very simple. I myself can not even code, I just used a drag & drop program from Trade View X and now I am automated.
