I was thinking of basing a system on time. Just time to make it simple, I was thinking of when countries have their rush hour when they go to sleep when they wake up. Correct me if I am wrong but I think that countries move currencies the most as they out number traders in size and in the amount of money they have. So far I am testing out on buying the GBP/USD: long 7am short 11am close 3pm. So far they are no stoplosses or take profits. I would apprecaite any help on developing a strategy based on time: what currency? what time?
