What results do you get post 2013?

Since 2013, BCC=0 timing was a wash, with not much change in the metrics.

  Screen     CAGR  SAWR  GSD   LDDD3  MDD    UI   Sharpe    From       To
chg_average  1.0   1.3   -2.6  -2.2   11.8  -2.7   0.10   19850201  20251128

I attribute this to the absence of a major bear market. BCC timing will be most effective during major bear markets like 2008, 2002, and 1974. But these infrequent events make backtesting difficult. Bear markets since 1950 (gtr1 cycle returns using 25% Peaks and -20% Troughs):

"To know when to switch between them, SPY-COMP monitors 6 different economic indicators. When no indicators are signaling recession, the strategy remains long SPY, regardless of what price is telling us. If any one of those indicators is signaling a potential recession then it defers to trend-following to confirm, either going long SPY if the trend in equities is up, or IEF if the trend is down."
