Nah 5k, but I think opening amounts are less. Intra session margin is around 500 per contract. But positions need to be closed by 15:45 EST USA.
Only time, is when I just randomly enter a trade without fear instead of waiting for ideal entry that my gut is telling me. I've found that 'gut feel' is better than any algo out there.
Did some gold trades, trying to catch the turn, got out with minimal gains. Didn't quite hit secondary trendy.
