The closes
The disparity index
The disparity index is +2.38%: the close is 2.38% above its 14-bar average of 2,386.74.
- The direction
- It was +2.25% on the bar before, so it is rising. The close last crossed above its average 20 bars ago.
- Against your bars
- It is higher than 95% of the other 66 readings in your bars: one of the most stretched above the average in these bars. The highest reading was +2.74% (17 bars ago) and the lowest -1.82% (39 bars ago).
- Read it with care
- A stretched reading says the close is far from its average, not that it must come back: in a strong trend it can stay stretched for a long time. What counts as stretched differs from market to market, so the page ranks it against your own bars.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

How far from the average?
The disparity index is the close's distance from its moving average, in % of the average. Steve Nison described it as a tool used by Japanese traders: above zero the close is over its average, below zero under it, and a reading far from zero shows a stretched move. Because a 2% gap is a lot in one market and nothing in another, the page ranks today's reading against every reading in the bars you paste.
Measure the same stretch in standard deviations with the z-score calculator, draw fixed bands with the moving average envelope, and compare averages with the moving average calculator.
