futures? or Stocks? (quite relative actually, depending on trading style.) Scalping YM is fast - but not nessacarily easier.
If we are talking about Futures, Yes. Definitely in terms of fills. To me, Trading the YM is like trading the old Nasdaq II stocks. (Like KLAC). I personally prefer trading the NQs, because of the needed large stops to trade the YMs. It doesn't really fit my style. The NQs trades more orderly IMO.
