Supply seems to be stronger than demand above the 4535 area. Those who trade the daily would be using daily bar intervals but those who can shift to smaller bar intervals like myself are also looking at the hourly. The hourly DL has been breached.
Remember that the longer timeframe -- the weekly in the case of the SLA -- always holds the cards. Price broke the DL last Thursday but bounced nicely off the weekly median, which it tested again on Friday (which is why, for all those who ask, one should trade within the weekly, even if trading a tick chart). And this morning it made a higher high generating a new DL fanned under Friday's low. Whether or not this will be broken before the end of the day remains to be seen.
