When whales pump, they usually never pump against trend. They pump in right time, when the price is primed, so they don't have to spend so much BTC to reverse the trend. Fighting the trend is very fooling thing to do.
I was talking about this in the Slack yesterday when someone was saying to put in support at 5800 (but trend line at 5500). A buy wall in a downtrend is really just a buy order. Buy walls work best in an uptrend, sell walls work best in a downtrend. Pumping works best when it's already ready to go and just needs a little encouragement. Good whales/market makers/pumpers aren't fighting the trend, they're emphasizing it!
