ok, I know waht I did wrong here. out @ 7. Wrong formula was used. Hyperscalper I'll be back in a bit to answer.
OK, well, the fives are pretty nutso quite honestly. Unless you're 100% correct on direction (which is the only time that I ever touch them) for a particular setup then I wouldn't mess with them. Price bar structure is the same within my method - so I get/understand the ability to trade the really short duration bars - but I am just not good enough to do it at this point. I agree that the only way you reasonably could would be to have the trade decision process automated, or the execution, or both. and, you better have a damn high hit rate on them too. as for holding through expiration otherwise - it's just a function of where you think the close will be relative to any of the strikes. on this last awful trade i just took above - i was certain the close would be > 749, which was why I kept adding to the trade. I've done that dozens of times and hit 2-5x in an hour because my average price ends up being so low. Of course the first time I journal that I ended up using the wrong formula, but still. You can connect to NADEX's API for $1k + I think $0.90/contract extra. It's in their terms if you haven't read that already. But you will have to have someone very good at writing because there is little/no support on the API that I found. I am not a programmer though, so take my input FWIW.
Sold the 9PM 1.0738 EURUSD @ 47/100. Will add all the way up to 80/100 but for journal's sake, the trade is @47. Stop @ 90.
