Options B and C: Watchdog + Tactician Combinations
Both combos failed walk-forward on 2026-04-17
The claim
We tested two combinations of the Watchdog (cycle filter) and Tactician (30-day momentum) bots. Option B: 50/50 independent capital split. Option C: Watchdog-gated (Tactician trades only when Watchdog=LONG). Continuous-run results looked excellent — Option C returned +218% vs Watchdog-solo's +202% with lower drawdown. Looked like a strict upgrade.
Root cause
Split the data into 3 non-overlapping windows. Neither combo reliably beats Watchdog-solo. Option C: wins 1/3 windows on return (loses W2 by 7pp, W3 by 17pp). Option B: wins 1/3 windows on return AND 1/3 on drawdown. The +218% edge was W1-dominated — a bear-market artifact that doesn't generalize to bull regimes.
Lesson
Continuous backtests can look great and still fail walk-forward. The 3-window check is the truth serum. Both combos provide marginal drawdown protection at meaningful return cost in most regimes. Neither is a clean upgrade over Watchdog-solo. Signal correlation (~70%) means the combos don't diversify enough to overcome the fees and tax friction they add.
Current status
NOT deployed. Real capital stays in Watchdog-solo. Tactician continues standalone on paper tier.
