I drew some yellow lines to show the crack and the bounce back to the crack.. your line 5 was not quite at the low of that base .. but you can see that it bounced back to that base.. As far as holding time, when your working off 1hour candles, then you should expect it to take a few days to return to the base.. however I often get a profitable trade in an hour or two... and then im reloaded to buy again..
