I opened the CSV that this code referenced. It actually has parameters for individual dates, meaning the code is going date by date and is highly overfit. You know, even I could create a strategy that never loses by telling it exactly what to do on any given date through the lens of retrospection.
Does Quantopian not screen for these kinds of scams? Seems highly suspicious, not to mention the website link is sparse and looks very unprofessional. Maybe this is the "real deal", but if it were, I doubt he'd be sharing it and would probably be on his own private island, not trying to rope a few greedy, sad souls in. Pardon my skepticism. Maybe (I hope) I'm wrong.
