What do you mean by "swing low"? A line of support connecting 2 or more lows? 

The swing low is just the low reached by stock price on each significant pull back in price as moves. They should stand out on the weekly chart.

How was 3.72%-4.96% calculated from 0.809 ATR ? 3.72-4.96% of what? And with that 3.72-4.96%, how do you then calculate the price of the stop? #confused

Sorry, my bad. The % sign should be an x (i.e. multiplied by) really. It was just how I was referencing them at the time when I wrote this. So the range would have been be 3.72x to 4.96x the 200 day ATR.

I'm using Prorealtime and charting these old charts from 2012 and they look completely different from what you posted below using stockcharts. Any explanation for why?

Prorealtime doesn't always adjust it data for splits etc, so if you are looking at old charts then there's a good chance that the prices will show differently now, to how they were back then.
