When you say free, if you are asking if you can't lose money, it looks like 'if" you can get this off at the place I simulated your max loss without fees is about $200. These markets are very wide and you will have fees. The risk/reward looks good if you can get this on at the right price. IF> >>, This is also a very narrow range for ES so the odds of being near 2900 are low. You have to take expectancy into account too.
IMO-
Risk/reward good.
Odds of a win, low.
Odds of getting done near this price low.
