Quote from BCE:
A thought, meant to be useful and not to tell you how to trade. But "mental stops" on this can be dangerous as this can make very big moves in no time at all. I find it more useful to use real, hard stops and of course you need to decide where to place them in different market conditions. Then if you get stopped out you can reenter. At least that's what I do. Good luck with your trade.
ADD I thought for a second you were trading the 7-11 contract, but I see it's the 8-11 contract. None the less I still stick to my remarks. Breaking news can cause huge moves and if the stop isn't a hard stop you won't have time to check out of your position. Again, good luck to you.
