BBBDXY-9 - Intraday/ Swing

What it is
A chart-grade USD basket that outputs full O/H/L/C candles. It combines nine FX pairs using weighted log-returns and geometric aggregation, then rescales to 100 at an anchor. You can build from 1m, 1H, 4H, or D and analyze it like a normal chart (drawings, structure, bar replay, and a clean Source output for other tools).

Why another USD gauge?
A legacy EUR-heavy USD measure can, at times, behave close to an EURUSD proxy and under-represent moves versus other majors and Asia EM. A diversified basket helps capture USD dynamics beyond EUR-centric effects. This study is independent and does not rely on third-party brands.

Basket (defaults are editable in Inputs)
Pairs used: EURUSD (inverted), USDJPY, USDCAD, GBPUSD (inverted), USDMXN, USDCNH, USDCHF, AUDUSD (inverted), USDSGD.
Inverted means the pair is flipped internally so rising values reflect USD strength. Weights default to a diversified mix and can be customized.

How it works (high level)

Sample each component on the chosen base timeframe.
Compute log-returns versus the anchor, multiply by weights, sum, and exponentiate (geometric combine).
Re-scale so the index equals 100 at the anchor.
Optional: plot an arithmetic comparison line.

Base-TF and aggregation rules

Build from timeframe: 1m, 1H, 4H, D.
If chart TF is greater than base TF, aggregate up from the base TF (no down-mixing).
If chart TF equals base TF, show native base candles.
If chart TF is lower than base TF, sample the base TF (step-like).
For intraday precision and exact wicks, choose 1m as base and view higher TFs by aggregation.
For longer history with fewer requests, choose 1H, 4H, or D as base.

Inputs (overview)

Build-from TF (1m, 1H, 4H, D) and a feed prefix if your broker symbols require one.
Per-pair weights (editable).
Anchor date and time (chart timezone) plus optional auto-rebase to first available bar if the exact anchor is missing.
Arithmetic comparison line (optional).
Source output selector (Open, High, Low, Close) for downstream tools.
Custom candle colors.

How to use

For granular intraday structure and wick accuracy, set base TF to 1m and view higher TFs by aggregation.
For swing and weekly context, set base TF to 1H, 4H, or D.
Keep default weights unless you have a specific reason to alter the basket.
Rising index suggests USD strength versus the basket; falling index suggests USD weakness.

Notes and limitations

Depends on availability and quality of the underlying FX symbols on your data feed.
Indicator only; no financial advice, no alerts, no orders.
No external open-source code reused.
Past behavior does not guarantee future results.

Figure (publication image)
Top: a legacy EUR-heavy USD index on 1H. The horizontal line marks a local swing high; price stalls and rolls over beneath it.

Bottom: this diversified USD basket on 1H. The horizontal line marks the same calendar window; the advance extends differently into that zone before rolling later.
This side-by-side illustrates that a EUR-centric gauge can diverge from a diversified USD basket. Similar divergences appear at other points; the example is illustrative and not a signal.
