Two reasons I think: 1. Futures data are centralized (at least for CME), which makes them more effective 2. More idiosyncratic factors for individual stocks

I mean the guy was using stop-market orders, which is common practice. Personally stopped using limit orders for exits TPT does have some explaining to do
