Percentage Hughes Breadth Momentum Oscillator

The Hughes Breadth Index is also known as the The Hughes Breadth-Momentum Oscillator.
It measures the ratio between the difference of advancing and declining issues in an exchange, to the total number of issues. The theory behind the index is that increases in stock prices are preceded by strengthening internals of the market, and the reverse is true for decreases in stock prices.

The calculation is: H = (A-D)/(A+D+U)
Where

      H = today's 1-day ratio of net advances to total issues trades
      A = number of advancing issues
      D = number of declining issues
      U = number of unchanged issues
(A+D+U) is the total number of issues traded each day. Typically the indicator is calculated on the NYSE data, though similarly it can be calculated on other markets such as Nasdaq.

In this implementation the index is 'normalized' so as to get positive numbers, between 0 and 100 percent.

This index based on daily data is quite erratic, and is typically smoothed by simple or exponential moving average in order to facilitate analysis
