"it has to be automated to take the trades in your account itself.  I like the idea of automating a strategy bot to just run and catch trades all day"

Maybe automate a subscriber email notification (along with the trade execution on your side). If the email followed a standard template (kept the same format, subject line, trigger words, etc., then members could use the API's for their platforms to trigger a trade on their side when an appropriate email arrives. The template would have to be exactly the same every time....or the coding would go from quite simple to difficult.  The potential lag for email wouldn't matter all that much for the longer time frames. 

I can almost picture a python solution that would accomplish this....but I hear that ChatGPT can take plain language coding problems and deliver working code these days
