# ARBR emotion index

## 1. Introduction

(AR) and willingness indicator (BR) are indicators of the technology to analyze the historical stock price, in which the popular index is more attention to the opening price, which reflects the popularity of the market; the willingness index attaches importance to the closing price, reflecting the market The degree of the willingness to buy and sell, the two indicators were different angles of the stock price volatility analysis, to track the future trend of share price common purpose.

## 2. Calculation formula

AR = SUM(HIGH-OPEN,N)/SUM(OPEN-LOW,N)*100

The sum of the difference between the highest price and the opening price in the last N days is divided by the sum of the difference between the opening price and the lowest price, and the ratio is multiplied by 100.

BR = SUM(MAX(0,HIGH-REF(CLOSE,1)),N)/SUM(MAX(0,REF(CLOSE,1)-LOW),N)*100

In the last N days, if the highest price of a certain day is higher than the closing price of the previous day, the difference between the highest price of the day and the previous closing will be added to the strong days sum. If the lowest price of a certain day is lower than the previous closing, the previous closing will be combined with the difference in the lowest price of the day is added to the weak days sum. Finally, divide the strong sum by the weakdayssum, and the resulting ratio is enlarged by 100. Where N = 26
