i know that ym future options has very little volume; but i am interested in talking to someone who has traded these. my main questions are: is the margin for each lot any different than es or er2? if so , can someone give me an example? (ie:using ib) how do you feel the liquidity is effecting your fills? any other points you may want to make i would welcome. i see an april 11,300 going for 5/9 bid ask. this seems to be a safer risk/reward to me than an es or er2. this trade is 9% otm and 9% for es gets 1.10 and due to the multiplier(.5) , it's effectively .55. maybe there is a multiplier for ym? can ym options actually return 8 to 10 times an es and 5 times er2? maybe taking into account higher margin we may end up being equal on return. i just never traded these...yet. i do have much experience trading the es and er2.
