I think UOA has become so widely accessible and used that there’s lot of pump and dump going on, especially with “cheap” options where it doesn’t take a lot of capital to generate a scan hit. It doesn’t mean that one cannot make money, just that it’s not based on detecting what big guys are doing. More like low float momentum trading, imho.However, what we are trying to understand here is how to discriminate between 'good' signals (the ones you posted) and the 'fake' ones, (like the one I posted). In my experience, the latter ones largely outnumber the good ones and I have not found a good way to say which is which.
But now things are not easy on all fronts. Now is good time to see what, if anything, acutally has edge!
