That's assuming no one's stupid enough to over-leverage themselves....which I guess for you I maybe shouldn't have made that assumption? you're right. Average down. That's way better.
Another thing that kills is making assumptions. Ask any broker and they'll tell you that 95% of their customers overleverage their positions. This is number one cause of ruin. Let me ask you paper trader, how much do you think one should have in current bankroll to trade 1 ES (real trading)?
