@pratik2358, if you dont know bro how to calculate RR then you should learn that instead of simply commenting. Anyways let me help you with that also
RR = (400-250)/(420-400)
= 150/20 = 7.5.
what else you want RR of 100?
@pratik2358, does nt mtr to me whether you are a new comer or not... i shared my view its on you to take it or leave it... and in markets there is no high and no low... just ride the trend till it bends...
