for me a lot depends on my frame of mind. Sometimes I can easily take two positions in the same pair and unload one and then the other. I often find that I do make more on the second one. It all depends on how much risk I am up to taking how long I think I can hold without feeling trapped.....How soon I have to leave to go get someone or pick them up....And for instance today I have made 8%, really that is a super gain, people hope to make that in a year so I also try and stay realistic.
