has anyone experimented with a 7 minute chart? i have been doing this for the past few days because I was wanting something just a bit slower than the 5 minute and not quite so long as the 10 m. I've got a timer which loops on my other laptop so i can keep track of when the bar is about to end. Feel divided about it tho as on twitter when i post about charts who the heck else uses a 7 m chart. maybe the whole idea is silly.
