I almost think that Gain must have not adjusted their pricing for the micro because the number you quote is astronomical.I use gain and IB. Gain had ridiculous fees of $3.60 round trip. Didn’t try with IB yet.
But, these micros are going to be a much better option than spy and qqq. Want to swing over a couple days or weeks time ? No problem, and no wash sale issues.
I’m a futures trader. I don’t claim mark to market. But I will definitely give these a go when I’m looking for some type of bullish swing trade in the near future where I won’t lose sleep. I’ll be able to pull a b1s2.....take 100 handles of heat and still be able to sleep like a baby!
With IB, its 47 cents per side for both MNQ and MES. This means that for MNQ, you need 2 ticks profit to cover commission, and then you're left with 6 cents. For MES, the $1.25 profit on 1 tick leaves you with 31 cents.
As for spreads, the MES has been pretty tight, usually 0.25, but for MNQ, it can easily be 1 point wide, but this is me looking while we have been getting these pretty fast moves.
For both MES and MNQ, the highs and lows of bars can be off by a tick, but in the whole grand scheme of things, I don't think any strategy will suffer greatly by switching between these instruments.
