Of course trend following is alive - there are hundreds of CTA funds and managers. Whether it makes money is a different story entirely.
All of the data and inputs are public and the strategies are trivial to replicate, so we're at the point where Wall Street analysts publish estimates of CTA buy/sell flows based on price level takeouts.
