Oh, I knew I would forget something. The time frame is 30 min.
It is really simple. I think we should see how it performs before we try to find a confirmation. I spend quite awhile looking at things that would confirm it, but I ended up just going with the simple cross. Just to clarify the post above, you won't need a trailing stop or a stop loss. just have the next cross be the end of the current trade and the start of a new one. I went back a couple of months and just got a ruff estimate of how just the cross buy itself would do and things looked pretty good especially if you traded all 4 pairs at the same time. If you can work that into the program, that would be ideal.
