This is why ema 7 is crucial as a scalper.

if you trades between range 1-5 minutes, the ema line either become the support or resist. this is helping you either decide to enter or even quit your position.

and as daily itself we can make $RE as example.
After the price pulling back they hit EMA 7 on daily basis. as a scalper, this is great opportunity to take opportunity on the bouncing moment.

Do you guys also using EMA in your trades???
