YOYO index

I found this indicator while reading one of my favorite books on volume and didn't see it in the public library, so I thought I would code it up. Pretty simple actually, but I really enjoyed using it.

"Created by Richard Arms Jr. and explained in an article he penned for Barrons's in 1998, it combines the daily spread of a stock or index and divides the daily volume by that number to see how many shares it needs to trade in order to move the issue through one point of its daily spread. This is usually considered a broad market indicator, but is useful for individual issues as well. On a historical basis more volume is required in order to generate a wider price swing at tops, while the opposite is true at bottoms. This is explained by the emotions of greed and fear. At tops there is complacency which requires ever greater volume to get prices to swing in wider ranges, while at bottoms fear can cause greater swings on relatively lower volume."

This indicator is useful at identifying divergences and trend confirmation. It is also effective in shorter time-frames as well as much longer time frames. The original formula does not use any smoothing, but I have included it as I feel it dulls some of the shorter term sharp turns inherent in this indicator. There is also no adjustment to the length of Richard Arms' original, so I include it in case you feel you need to 'play' with the settings.

Remember, you are responsible for everything you do with any indicator and those results are entirely yours to claim, so by default I am not responsible for any losses nor am I entitled to any gains from the use of this indicator.
Enjoy and as always good trading,
