An in call is right when the price rose before the next call; an out call is right when it fell. The latest 12 of 32 calls shown.

How the play works

  1. In when the 14-day MFI crosses up through 20.
  2. Out when it crosses down through 80.

The creators also stress divergences, which this rule ignores.

The case against

Valeriy Zakamulin tested moving-average timing on up to 155 years of U.S. stock data and found no statistically significant edge in the second half of that record. The rules earned their keep in a few severe bear markets and lagged buy and hold for long stretches in between.
