But in futures it is concomitant. YM goes up 500 points it is $2,500 per contract. ES goes up 40 points and it is $2,000 per contract. There is some relevancy there. The amount of money to be made on each is very similar. As for which leads which? Tough call there.
Eventually it paid off, but you should have listened to me when I said we go back to 2470-75. You could have made twice as much money...
