The call
The model leans bullish on US Dollar Index (DXY): its score is +35 on a scale of -100 to +100, above the +25 line, and it has held this view for 30 days. Confidence is high.
- 100% of the weighted components agree with the call.
Calls change only when the score moves clearly across the line: a bullish or bearish call stays until the score falls back inside ±10, so it does not flicker. A call is a view of direction over weeks, not a forecast of tomorrow.
Why: what makes up the score
| Ingredient | Reading | Weight | Points |
|---|---|---|---|
| Trend | Up 0.7% over three months and up 3.1% over twelve; price is above its 50-day and above its 200-day average. | 53% | +28.0 |
| Value (vs 5-year average) | Price is 0% below its five-year average; large gaps tend to close slowly, so this signal leans against the move. | 12% | +0.8 |
| Carry (interest-rate gap) | Holding USD against the other five currencies in the basket earns about +1.54 points a year in interest (policy rates 3.88% against 2.33%). | 23% | +7.1 |
| Central-bank drift | Over six months the rate gap moved 0.11 points against USD (central banks tightening or easing at different speeds). | 12% | −0.8 |
| Macro drivers | How the instrument has reacted to the dollar, equities and US rates over the past year; see the drivers table below. Shown for context; not in the score (it did not help in testing). | 0% | – |
| Score | +35 | ||
Each ingredient is scaled from -1 to +1 using only past prices and published rates; points = weight × reading × 100. The weights were set from published research before testing; an ingredient that clearly failed in the 2010-2017 test period was taken out of the score. Full method.
Price chart
Risk levels
Levels for a long idea, from recent volatility (the 14-day average true range, ATR, is 0.5201 or 0.51% of the price):
The "wrong beyond" level is where the call's reasoning would no longer hold on current volatility; it is a way to think about risk, not an order. Objectives are simple multiples of that distance. Volatility now: 5% a year , higher than 61% of the past year's days . Moves can gap past any level.
Interest rates behind the pair
A positive gap means holding the first currency earns more interest than the second costs. Rates come from the central bank rates page (BIS and central banks). Some currencies are managed by their central banks, so their prices do not move freely .
Positioning of traders (CFTC)
Positioning is not in the score: we only have two years of weekly history, too short to test fairly. It is used for the confidence level: a call that agrees with a very crowded trade is marked down, because crowded trades can reverse fast. Full report for us-dollar-index.
How it reacts to the big drivers
| Driver | Link over the past year | Driver over 3 months | Pushes the instrument |
|---|---|---|---|
| US equities | −0.41 | rising | down |
| US 2-year yield | +0.41 | rising | up |
"Link" is the correlation of 5-day moves with the driver over the past year (between -1 and +1; below 0.15 in size is ignored). The driver's 3-month direction is scaled by its own volatility. For currencies this table is context only: in testing it did not improve the call.
Seasonal pattern
In October, US Dollar Index (DXY) has averaged +0.73% and risen in 58% of the 19 years we have.
Context only, not in the score. For most markets a calendar pattern is weak and unstable; farm goods have the clearest seasonal logic (planting and harvest).

On a single instrument luck dominates: a model that is right a little more than half the time still has long losing stretches. The pooled result across all pairs is on the forex page. This is a replay of rules, not a live record. The live log of every daily call started on 16 Oct 2026.

About this call
US Dollar Index (DXY) is the US dollar index, a basket of six currencies. Basket of six currencies (euro 57.6%, yen 13.6%, pound 11.9%, Canadian dollar 9.1%, krona 4.2%, franc 3.6%). The call comes from one scoring model used for every instrument in the same way, described on the method page. It reads prices, interest rates and (for context) trader positioning; it does not read news or predict events, and it can be wrong for long periods.
Risk warning. Educational research, not personal advice or an invitation to trade. Forex and commodity trading, especially with leverage, carries a high risk of losing money quickly; most retail accounts that trade leveraged products lose money. Past behaviour of a model does not predict the future.
