Price correction or pullbacks are pretty much the same but asking on how deep it would be then that would always be a question of all that cant really be answered
but somehow with some help of technicals then you can presume out on where could possibly the price be ending up in case for some price pullbacks but always
put up in mind that it isnt always accurate nor precise when it comes to technical analysis but at least you do make out some presumption due to some basis
rather than on blindly presuming without any having done some plotting.You can always set on your own buying point.
