ya every ema things work fine on a trend
but how to avoid when there is no trend

after 20:00 to 8:00 there will be no movement in the currency just a standby mode after 8:00 when markets open it give a claer signal either markets goes up or down
it can go to 15:00 and than can chage or it will go to 20:00 and than the market become on standby mode
on monday trend is great u can at least make a 100 pip in every pair u trade but on right way
fraiday is worese day no one enters in it full of false signals
i hope u understand
