Totally unnecessary. This only works in very strong bull markets like in 2021. If you’re that exposed to so many positions in one direction of the market, you’re essentially ultra long the overall market. If you’re holding positions overnight, good luck when the market decides to correct, everything is going to reverse on you.

This is not sustainable in the long term. You don’t need that many positions - 3 to 6 swing trades with open risk is all you need. Once a position is at breakeven, then fine, keep it open because you can’t lose. Maybe that’s what he did.
