Heck, I learned to take turns in kindergarten!
I think many here missed that important life lesson.

What are you talking about ? I have never been a kindergarten, and I do better than most in trends and turn.
lol please don't bother engaging with me. We all know you've never advanced beyond the kindergarten stage. I'm rooting for you to pass pre-k in June.

The problem for someone like surf is that he doesn't understand the constraints his PhD acquaintances are working under. Classical statistics has no clue how to measure trends, so they make assumptions like linearity, stationarity, a Brownian component, etc. Being off by just a little can lead to very wrong conclusions. We saw a good example of this recently where the weather models that predicted NYC would be completely blanketed by the blizzard were off by tens of miles and most of the city was spared the worst of the blizzard. Classical stat has assumptions that just don't apply to the markets, which is why most statisticians aren't rich.In statistics, there is a clear difference between deterministic trends and drifts. And it is possible to have a random walk combined with a drift or with a deterministic trend or both or by itself or etc. In trading, it probably does not matter to most as terms like drift and trend are conflated, especially for those trading with technical or order book set-ups. But if you run a statistical framework it probably is wise to be aware of this.
I know only long, short, and no trade. Is that good enough to pass ?
