Does the strategy do better when the market is falling (SPY below its 200-day MA)?

What this means

On 15m, setups taken while SPY was below its 200-day average did much better (+0.34R, 52% win) than the rest (+0.06R, 42% win), and all three bear episodes were positive. But three episodes is a tiny sample: three out of three could happen by chance one time in eight. A plausible reason is that long-only dip-buying setups bounce harder after broad sell-offs, but the data cannot confirm this.

The explanation is our best reading; the data shows the result but not the cause directly.

Hypothesis
Long-only harmonic reversals earn more when SPY is below its 200-day MA.
Method
15m TradingView setups (16,496), split by SPY vs its 200-day MA; replicated across two sweeps; per-episode breakdown.
Result
Below: 1,410 setups, 51.7% win, +0.340R. Above: 15,071, 41.7%, +0.056R. All three bear episodes positive (Oct 2023 +0.78, spring 2025 +0.29, spring 2026 +0.31); lifts 6 of 7 patterns. Sign test on 3/3 episodes p = 0.125.
How much to trust it
Medium: large trade count but only 3 independent bear episodes; 15m history capped at 3.1 years
Did it change the live rule?
No.
