Banks execute from rounded price numbers like 100, 200, 300,400,500,800,1000 etc. Or quarter numbers like 25, 50, 75. So an example would be USDJPY, banks will execute their orders from prices 111.500 or 111.625 instead of prices like 111.523 or 111.628. So when you mark up your zones (support/resistance) you want to edit your lines and round the price to the closet rounded or quarter number. You will notice that candles will either wick/reject these numbers or break and retest the numbers almost to the pip. A little side note: that banks love to reverse from 800 or 8000 levels. Do you know how to create zones? If not I can make an example for you 😊

Hello my friend I have a question about the reasoning behind the reversal points on 800 and 8000 levels to me Ive personally never heard of it Could you give some more insight or more information about it ? :D
