Learned Pine Script, built an automated trading system, and it's running live

After one cycle on this Eog st1 and QL st1, I learned a new language (Pine script) for trading on some level. Made an automated system, and backtested it. It seems to be pretty profitable but you know historical data are just history and I will see it in a real life. Did also bridge with one service where a script is made - running and then via this bridge running on my broker's MT4 and right now it is fully running on my demo account on my let's say mini server which should run 24/7 and after one month if this is profitable I will make it as a real account and continue. Of course, besides that, I will probably try to make several other profitable systems, back-test them, and if they are good so make them run in a real-time.
