look the spoos are going to 500 and if we bottom at that level and volatility collapses then we are looking at a 5 point daily ATR........thus i think its a good idea to have a $5 tick in ES.........YM has it, NQ has it........ER2 has a $10 tick and even that is preferable to a $12.5 tick.
more ticks = more profit opportunities
