Bitcoin: The Golden Ratio Multiplier advanced with Z-score

What this does: We took the classic Golden Ratio / 350DMA idea and ported it to TradingView, then standardized it with a single Z-score. The three core bands are the 350DMA multiples (1.0×, 1.6×, 2.0×). We define their Z values and add two outer bands to complete a 5-level scale:

0.625× 350DMA → Z = +2

1.0× 350DMA → Z = +1

1.6× 350DMA → Z = 0 (golden-ratio mid)

2.0× 350DMA → Z = −1

2.5× 350DMA → Z = −2

How the Z-score is computed:
We take the **price-to-350DMA ratio**, locate it **between the two nearest bands**, and then measure its **position on a log scale** (because the bands are multiplicative). That position is **linearly mapped** so each band-to-band step equals **1 Z unit**: 0.625×→1.0×→1.6×→2.0×→2.5× becomes **+2 → +1 → 0 → −1 → −2**. If price sits **outside** the outer bands, the Z-score simply **extends past ±2** (optionally clamped in settings). Positive Z means price is **below** the 1.6× mid; negative Z means it’s **above** the 1.6× mid.
