I thought slope would be a clean trend indicator. Turns out it’s mostly noise when calculated on raw price.
Fixed it by first smoothing the price with a fast EMA and then calculating the slope over the log-transformed series. Still a bit noisy, but now at least the sign and magnitude mean something.
Slope is useful, but only after you’ve de-noised and de-biased it.
