Only time I 'freestyle' these days is in the afternoon session during the final hour --- indicators are useless moreso then, s/r can disappear in a flash, and you have to (at least I think) trade exclusively on price action and direction. Might be less precise, but if you wait for a ton of indicator confirmations, you'll miss your entry.
I am cognizant of s/r, congestion, and hod/lod values - but the rest is pretty much totally discresionary. Not done too badly that way during that final hour, either.
