Momentum on a daily chart can be positive while monthly momentum is still negative. These conflicting signals are not noise. They contain information about the maturity and reliability of the current trend. Multi-timeframe momentum scoring synthesizes these signals into a composite that is more reliable than any single timeframe.
The basic approach assigns a momentum score to each timeframe based on where price sits relative to its moving averages and the direction of those averages. On a weekly chart, if price is above the 20-week and 50-week moving averages and both are rising, the weekly momentum score might be +2 (strongly bullish). If price is above the 20-week but below the 50-week, the score might be +1 (moderately bullish). The same logic applies to daily, weekly, and monthly timeframes.
The composite score is the sum across timeframes. When all timeframes align (daily, weekly, and monthly all bullish), the composite score is at its maximum, and the trend is in full agreement. This alignment condition has historically produced the strongest and most persistent moves. When timeframes disagree (daily bullish but monthly bearish, for example), the composite is weaker, indicating a less reliable trend.
The sequencing of momentum across timeframes tells you where you are in the trend lifecycle. New trends typically start on the shortest timeframes and propagate upward. Daily momentum turns positive first, then weekly follows, then monthly. This sequence of alignment is the momentum building phase, and it is the highest-probability window for trend-following entries.
Trend exhaustion shows the reverse sequence. Momentum on the shortest timeframes starts to fade or reverse while longer timeframes remain positive. Daily momentum weakens, then weekly follows. When the shortest timeframes have turned while the longest are still positive, you are in the late stage of the trend, and the risk of reversal is elevated.
For position sizing, the composite score provides a natural scaling mechanism. Full position size when all timeframes agree. Half position when only two of three agree. No position (or reduced position) when timeframes are in conflict. This approach naturally increases exposure during strong trends and decreases it during ambiguous conditions.
The specific moving average lengths and scoring rules can be customized, but simplicity tends to outperform complexity. Using 20-period and 50-period averages on each timeframe, with straightforward scoring rules, captures most of the information without overfitting. Adding more moving averages or more complex scoring rules tends to improve backtests but degrade live performance.
One practical refinement: weight the longer timeframes more heavily than the shorter ones. Monthly momentum is harder to establish and more meaningful when it is present. Daily momentum can flip back and forth quickly and is more prone to noise. A weighting scheme that gives monthly momentum 50% weight, weekly 30%, and daily 20% produces a smoother and more reliable composite than equal weighting.
