I just do not believe in automation, if it was that easy we all be millionaires by now. Also, noone to learn from either. So spend all that time and no results to show for it.
Not believing in automation? If you are good at coding you would "just" let the code do what you normally would do manually.
Of course coding isn't easy, specially not if you want your code to take in account a lot of different factors or if you want the code to learn variables but nothing is easy if you really want to be good at it.
There is a reason why math and coding geniuses are working in finance these days. Automation is the future, in almost all industries. It has been going on for decades already and it's not going to slow down any time soon, quite the opposite even with AI growing as fast as it is.
Not everything can be automated, not every trading system can be automated, but if it can be automated it will be done at some point. If it can't be done right now there is a good chance they will just keep looking and find a way to do so in the future.
Edit: i am not a coder myself and i do not have an automated trading system. My system probably could be automated but would be very complex to code. I have near 0 coding experience and learning the level of coding i would need to automate my system would take many many years. I am not interested in spending that much time to automate my system, i am just trading 2-3 hours a day anyway. I am satisfied with my alert indicators that i created myself, they are saving me a lot of time.
