The bars
The relative vigor index
The relative vigor index is +0.204, above its signal line at +0.168.
- The vigor
- Above zero, the bars have lately closed above where they opened: buyers had the vigor. Over the last 10 bars the open-to-close moves come to +20% of the bars' ranges (smoothed). It has been above its signal line for 4 bars.
- How it is read
- The idea is that in a rising market bars tend to close higher than they open, and in a falling market lower. The usual signal is the index crossing its signal line; many traders also watch for it moving against the price.
- Read it with care
- It needs real opens: if each open is just the previous close, it reads plain close-to-close moves. It crosses often in sideways markets and gives no timing for the next bar.

Where the bars close against where they open
John Ehlers described the relative vigor index in 2002. For each bar it takes the move from open to close and divides it by the bar's full range, after smoothing both over 4 bars with weights of 1, 2, 2 and 1. Adding up 10 bars gives the index; the same 4-bar smoothing of the index gives the signal line.
