I have also learned about a strategy like this, and when I stumbled upon WTC I saw a perfect pattern for swing trading since the second half of august.
Whenever the coin starts to get sold rapidly, it quickly recover to where it was previously. it's possible to make 1 or 2 4-15% trades per day.
For those with bravery or good intuition if they don't sell immediately, it seems there is a chance of much greater % profit as some spikes upwards don't stop immediately.
The same works in reverse it seems as huge buy orders get met with huge sell orders after that.
Hope this helps anyone.
