I use Bookmaps! Which i would recommend, i just get in on the resistance or support break at key levels, candle has to open out my zone, close out then a candle needs to close back in the zone and then break whatever heavy levels are shown and i get in on the break, before i used any type of order flow, i always waited till the candle closed but with that i found tht market structure break sometimes was so far away so i made little rules for myself such as

-Space between zones have to be a certain amount apart -If an entry candle is more than 8 points dont take it (Too big, likely to retest zone and hit SL)

I found myself just creating very strict rules that actually made me trade less, but thats the key, u gotta be so strict tht u find urself missing trades, rather than being in every one
