Quote from JSSPMK:
Why have you chosen YM over ES?
It is a good question and I already advised him about 2 months ago to switch. It has nothing to do with liquidity, but volatility and return.
The ES is simply outperforming the YM by at least 10-15%.
Consider this:
Between the Aug low and the Oct high:
ES gained 205 points : $10250 per contract
YM gained 1700 points: $8500 per contract
NQ gained 415 points: $8300 per contract
ER gained 110 points: $11000 per contract
IF (and it is a big if) Surf's system is profitable, he would get the best bang by using ES. Now somebody could make the case for ER, but I can understand if one doesn't like to use ER even for longer term.
But between the ES and YM, the ES is the clear winner, and why wouldn't Surf want to make an extra 10-15-20%?
Of course, when the system is losing, he loses less by using YM....
