Does The 'In & Out' Composite Gate actually work?
MARGINALReal but small -- not worth what it costs to run.
The claim
An 8-signal composite tells you when to be in or out of the market — Popular QuantConnect strategy
What we did
Tested against Buy & hold SPY / honest reconstruction.
The result
Result: Cuts drawdown (−31% vs −55%) for dSharpe +0.12 — but beaten ~3:1 by our Risk Reducer alone
Cuts drawdown (−31% vs −55%) for dSharpe +0.12 — but beaten ~3:1 by our Risk Reducer alone
Verdict
It works — a little. Eight stitched-together signals get beaten roughly three-to-one by one humble signal (our Risk Reducer). Complexity isn't edge.
