I don't think it's anything odd that you're struggling to go above 50%, most traders do afaik. I'd say you'd only profit properly if you took some risks and went past that 1:! ratio. Anyway if it was that easy then a lot of people would've still kept trading and profiting to this day, even I would have. But no, it really isn't that easy lol. As for bots well, they're bots for a reason. They don't have the same flexibility as humans do nor can you actually put said flexibility into it in the first place. It's only good for some specific periods.

What's a pinescript code? I have heard it this time and despite that I am not the greatest trader here but with that term you've mentioned got me curious on what you really trying to do. But if you're trying to beat the market, you can't beat it and that's why you have to be with it and just do what's necessary as an action and keep on testing strategies that will make you profitable and what's more comfortable to you in doing. Not all of them are going to be green days but somehow it is going to be with your few more tests.
Should be something used for scripting bots used in trading. Not sure how it works I just know of it but I've never used it.
