Description
The Efficiency Ratio was invented by Perry J. Kaufman and presented in his book "New Trading Systems and Methods".
It's calculated by dividing the net change in price movement over N periods by the
sum of all component moves, taken as absolute numbers, over the same N periods.
Interpretation
ER can be considered as a ratio of the price direction to its volatility. The more efficient the market is, the faster is its trend.
