The Technical Health Score is a 0–100 summary of the chart evidence calculated for the active timeframe. It is designed to make the condition of one chart easier to compare with another without reducing the underlying evidence to a simple signal.
The score combines five pillars: trend, momentum, relative strength, volume and structure. The current diagnosis is the plain-English band attached to that score after model consistency checks.
Important distinction
A score of 70 does not mean a 70% chance that the share price will rise. It describes current technical health under the OnlyCharts framework.
The five diagnosis bands.
The current version groups the score into five conditions. The display bands make the output readable; the score itself remains continuous from 0 to 100.
| Score | Diagnosis | Plain-English read |
|---|---|---|
| 0–24 | Critical | Severe technical weakness with downside evidence dominating. |
| 25–39 | Weak | Fragile conditions and limited confirmation of buyer control. |
| 40–74 | Improving | The evidence is strengthening, but not all pillars need to be aligned. |
| 75–89 | Strong | Broad technical health with constructive trend and supporting evidence. |
| 90–100 | Leading | Exceptional technical strength on the selected timeframe. |
The model also prevents an optimistic headline from contradicting several clearly weak pillars. That is why a chart with a reasonable numerical score can still be displayed conservatively when the evidence stack contains material weakness.
The evidence inside the score.
The pillars are not intended to be read as independent trading signals. A high relative-strength reading is more persuasive when trend and structure agree. Heavy volume is not automatically constructive if price and momentum are deteriorating.
Why the score changes by timeframe.
A five-year monthly chart and a three-month daily chart contain different information. The longer view can show a major structural recovery while the shorter view is correcting. The reverse can also happen: a short rally may improve the execution view without repairing the long-term structure.
That is why OnlyCharts recalculates the evidence for the active view. Compare like with like: use the 3M view for recent execution context and the 3Y or 5Y view for large structural context.
How to read conflicting pillars.
Conflicts are often the most informative part of the X-Ray. Common examples include:
- Constructive trend, fading momentum: the chart remains above trend, but the move is losing pressure.
- Improving momentum, weak structure: a recovery is developing, but price has not reclaimed the level that changes the wider chart.
- Strong relative strength, light volume: the stock is leading its benchmark, but participation in the current session is limited.
- Heavy volume, weak price action: activity is high, but sellers may be driving it.
Do not force every chart into a bullish or bearish story. The diagnosis summarises the balance; the pillar descriptions explain the tension.
How to use the score.
- Use it to orient yourself quickly.
- Compare the score with its diagnosis and the plain-English summary.
- Inspect which pillars confirm or contradict the headline.
- Check the same ticker on a longer and shorter timeframe.
- Use the result to prioritise further research, not to replace it.
What the score is not.
It is not a valuation, forecast, probability, target price, signal or assessment of suitability. It does not know your portfolio, investment horizon, liquidity needs, tax position or tolerance for loss.
The model and its display bands may evolve as the product is refined. The current score should always be read with the date, timeframe, market-data limitations and the individual pillar values shown in the X-Ray.
