Imo you are better off trading micro contracts and trading outright holding all day..or getting long es all day and shorting nq all day at certain intervals against it. spread trading can also wipe you out quickly and with no stops you better have self control to exit losers manually and pay double fees everytime a trade doesnt work and 4 spreads..so then add up your ratio..you have what 1 nq 1 mym n 1 m2k..so that is 3 round turns and 6 slippages. so on mini you are at 20 plus 15 plus 30 so 65 plus 12 so round turn just in slippage is 77 dollars!! be wrong a few times during the day and you will think twice about spreads
