by experience, you don't need more infos than those which are already available.
it depends on your trading style of course.
for scalping, i even tend to remove some infos on trigger TF, to get precise action picture, and add XU_TDI to help me pull the trigger.
the idea is to feel the wave and take action as soon as you have enough confidence to take action.
my trigger TF trend lines :
EMA9
LWMA36
MA50 smoothed
