Scalp trades - wait for confirmation

I’m trying to primarily trade S&R. However, I am looking at scalp trading in between this. My scalps consiste of the same S&R lines except these are weak lines drawn in at any point the price obviously bounces on the 4/1hr charts.

Do you wait for a confirmation of the break in these cases?
Waiting for a confirmation is likely to make you miss the move?
