You can trade on any time-frame really, even odd time-frames like 2-3-5 hours, once you begin to read into the price action I think timeframes become irrelevant, unless you go down to sub 1 minute timeframe.
Disliked{quote} yes I trade it on the 5min chart on EUR/USD during london/new york overlap. I have also been experimenting with it on the 4hour charts on various pairs. It seems to work well on that timeframe and most of the time it confirms my price action strategy that I use on the 4hour. Depending on how this goes I might replace my original strategy with this as I find it easier than trading price action with S&R levels.Ignored
