Yield Strength
NZDCHF Yield Strength — Bond Yield Spread Indicator Between CurrenciesThis indicator measures the relative strength of major currencies based on the yield differential (interest rates) of each country's government bonds, rather than price.
How it works:
Fetches the government bond yield (2Y, 5Y, or 10Y, selectable) for 8 economies: US, Eurozone, UK, Japan, Australia, New Zealand, Canada, and Switzerland.
Calculates the yield spread between the current chart pair (e.g., EURUSD = EUR yield − USD yield) and plots it alongside two EMAs (fast and slow) of that spread, signaling trend crossovers with a color change (green = bullish, red = bearish).
In parallel, calculates the yield spread for all 28 possible pairs among these 8 currencies and applies the same EMA-crossover logic to each.
Consolidates everything into a scoreboard in the corner of the screen: each currency gains or loses points depending on whether it's on the "strong" or "weak" side of the yield in each of the 28 pairs — producing a relative strength ranking of currencies based purely on implied monetary policy/interest rates, not price.
Why it's useful:
Yield differential is one of the main drivers of flow in forex (carry trade, rate expectations). This indicator translates that macro concept into a visual signal and an objective ranking, useful as a context/trend filter for swing trading, without relying on traditional price-based indicators.
How to use it:
Recommended timeframe: works best on higher timeframes — H1, H4, or D1. Since it's based on yield differentials (a slow-moving macro driver), it's not suited for scalping or very low timeframes, where price noise dominates and the interest-rate signal loses relevance.
Best used with the trend. Use it as a context filter, not a standalone entry trigger. When the spread and EMAs are aligned with the pair's price trend direction, it reinforces that the macro flow is "pushing" the pair in the same direction — giving more confidence to trade with that trend.
Scoreboard: use the strength ranking of the 8 currencies to spot "stretched" pairs (strong currency vs. weak currency) — usually the best candidates for trend-following entries backed by this macro driver.
Color crossovers (green/red) on the spread's EMAs signal a regime change — useful for confirming the yield trend is still active before entering, rather than already exhausted.
Technical: Pine Script v6. All 28 spreads are calculated locally from just 8 request.security calls (one per currency), working around PulseWire's 40-security limit even while analyzing 28 pairs.
