RN,
I have attached a chart with intra-day support and resistance I identified, though it's on a 1 minute chart the TF doesn't matter. Red lines are support, white lines are resistance.
Aside from from the trend (as I am only looking 1-2 bars forward on any TF), if we are playing the odds, there seems several ways of playing these - fading when price moves thru the initial level, or catching price near the most recent swing in anticipation of a return to the level.
The reason for the initial level, OHLC, on whatever TF, happens for a reason and it seems to be a focal point in directing the flow of money (eventually) on that given TF though it is still part of the big and bigger picture so anything can happen.
