When you say calculation do you mean support resistance points, or do you mean specific numbers on the futures that would trigger program buy/sell? I am familiar with both concepts. I trade stuff that moves with futures, if you can toss me a bone I will really appreciate it. I didn't know this is some sort of black box material, if this is some top secret discovery then never mind. I am sure everyone would love to find that one indicator that leads futures. So if you can give me a hint please do so. Nothing is a lock . . . I know a few futures traders at my firm. I am going to post it on my journal when I do find it. I thought there had to be something else that futures traders watch. Gotta go digging tommorrow.
