# Currency Strength

Currency Strength is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®.

Tracks the relative strength of five user-selected currencies by averaging each one's normalized close-to-open change across its four pairings in the basket and accumulating that average, with readings that reset each period. A configurable strength meter ranks the currencies while an optional scatter plot separates strength from momentum in four color-coded quadrants.

The **Currency Strength** indicator scores five user-selected currencies against one another and plots how those scores evolve across a chosen period. It's LuxAlgo's build of the [currency strength meter](https://www.luxalgo.com/library/concept/currency-strength-meter/): each currency's close-to-open change is normalized to a percentage, averaged across the currency's four pairings in the basket into a composite score, and accumulated until the period resets, so "strength" means measured relative performance, nothing vaguer.

## How to Trade the Currency Strength?

- **Ranking read**: currencies topping the meter are outperforming the basket over the window; those at the bottom are lagging, the raw material for choosing which pairs deserve attention.
- **Trailing strength lines**: the historical plot shows each currency's accumulated relative performance, resetting at period end so readings stay comparable across cycles.
- **Scatter quadrants**: each currency's current strength (vertical) is plotted against its change from the previous period's final reading (horizontal, scaled across the basket). Strong (green, upper right) is positive strength with a larger change; Improving (aqua, upper left) is positive strength with a smaller change; Weakening (yellow, lower right) is negative strength with a larger change; Weak (red, lower left) is negative strength with a smaller change.
- **Meter resolution**: raise it to expose finer differences between closely matched currencies.

The scatter view is the distinctive piece: by plotting current strength against the previous period's, it separates level from momentum: a currency that is strong-but-fading reads very differently from one that is weak-but-turning.

## What the Currency Strength Shows

- The trailing relative strength of the five selected currencies over a user-defined timeframe period, or a scatter plot as an alternative display.
- A strength meter whose visibility, resolution, position, and size are configurable.
- A scatter graph whose horizontal width in bars is set by Scatter Graph Resolution; the vertical extent follows the strength values.
- Under the hood, each pairing's reading is the normalized close-to-open change, (close − open) / open × 100, composited per currency across the basket.

## Frequently Asked Questions

### What does "strength" mean here?

Performance, precisely: the normalized close-to-open change averaged across the currency's four pairings in the basket and accumulated over the selected period. A stronger currency has simply performed better within that window.

### How do I turn readings into trade ideas?

Strength ranking narrows the field to outperformers and laggards; from there, verify relationships before committing. [Correlation Clusters](https://www.luxalgo.com/library/indicator/correlation-clusters/) groups instruments by how they actually move together, a useful cross-check against doubling up on the same exposure.

### Is the Currency Strength indicator free?

Yes. It costs nothing on the LuxAlgo Library. The page can also hand it to Quant, our coding agent, for hands-on testing whenever you like. You can also copy the source code from this page and run it anywhere Pine Script® runs.
