I prefer SPY over ES, why? SPY has a 1 cent spread, whereas ES trades in .25 ticks. Thats equivalent to 2.5 cents of SPY, overtime that extra spread adds up. Intraday 4-1 leverage is plenty. Plus its a lot easier to scale in and out with SPY given that you can buy/sell as little as 1 share. With ES you are stuck with 1 contract sizes
But wouldn't the lead/lag and higher cost lose that advantage?
So, basically it's good for lower volumes? Makes sense I guess up until the point where transaction costs are too high for daytrades...
