See i have some 3 rules i got from mahadfx ,when i open my chart the first thing i look for is a trend is it up trend or down trend..i get that from h4 time frame,the 2nd one i look for a break of structure with an impulsive move,like e.g...if its a down trend i look for a current break of structure the mark my supply zone on H1 or M3O...then patiently wait for the market to reach my ob. The 3rd one is my confirmation ...i scale to a lower time frame to see if the market reacts off my order block so i can catch a sniper entry with a pretty decent SL..if it does then i go in...thats how i became a profitable trader....dont forget the liquidity ,if you dont see the liquidity you'll be the liquidity.
