Well, most of the time I use neatest support/resistant levels; if I get a smooth momentum of market, the I carry that for the next S/R level!
D1 is a must as that is where most of the order flow is derived from. H4 to give more precision. H1, (M30,) M15 and lower for entries. In that order.
I am also a day trader, I prefer 5 minute chart to take my entry & exit decisions!
