I don't see the deals you made, can you share them again? Did you make sure you tested your system enough before quiting your major job? How consistent you wins are, and why do you think you can sustain your livelihood from just trading? I know people live by trading forex and even make good money, but those people work for proffesional firms with huge funds on their disposal, and their profits (ROIs) are not bigger than 20-30 percent per year.
I'm going to post them on regular basis here, this is the one the most recent (XBTUSD BitMEx):
An interesting pic could be seen 15th of May till yesterday at 4h chart. The BTC price was tracking inside a downtrending channel between two strong trend lines (horizontal resistance, formed by 3 tries of the price to break it out, and upwards trend line). That was a crossroads, but now the upwards trend is broken out, meaning that the bears took the control back for a while. The today's short was really confident here
No doubt, the system is tested. And my rule is to adjust it, as there is no limit to perfection.
The decision to quit is a serious thing, personally I was making a detailed plan of my trades after getting a constant result for enough period of time, combining major job and trading
