This concept is very simple.. Use round numbers as support and resistance, target the (.25 - .50 - .75) levels for take profit.. Basically, the rounds numbers are high liquidity zone (psychological and banks levels)
You can clearly see the price moving between those zones.
Recommanded timeframe : M30-H1-H4 (M15-M30) for entry..
I usually look at rejection at those levels for short or buy depend of the context.
You can place SL on the next .25 pips over the hard round numbers resistance-support.
Good Luck and if you have any comments, write bellow.
