The market is trending, not ranging.Who wants to dispute?
Which market? There are many of them.
Markets are random.
Well, I suppose any chart, most have a trend from the left to the right, and a few maybe 20% or less don't.Ok, the timeframe.I`m sure it`s an old adage, and back than folks were rather Daily/Weekly/Monthly traders, as far as the timeframe goes.It would be good know who and when first said that, but i`m afraid it`s not possible to find out.
But, regardless of the TF, be it 5Min or Daily, 80% of it trending to me seems valid.
