Williams %R is a technical analysis indicator used to identify overbought and oversold conditions in the market. It is calculated using the following formula:

Williams %R = (Highest High - Close) / (Highest High - Lowest Low) * -100

In MATLAB, you can calculate Williams %R using the following steps:

- Load the historical price data of a stock or asset into a variable, such as priceData.
- Calculate the highest high and lowest low prices over a specified period, such as the past 14 days. You can use the functions max and min to find these values:

1 2 |
highestHigh = max(priceData(1:14)); % Highest high in the past 14 days lowestLow = min(priceData(1:14)); % Lowest low in the past 14 days |

- Calculate the Williams %R value for each day using the formula mentioned above. You can use a loop to iterate over the price data and calculate Williams %R for each day:

1 2 3 4 5 6 |
days = length(priceData); WilliamsR = zeros(1, days); for i = 1:days WilliamsR(i) = ((highestHigh - priceData(i)) / (highestHigh - lowestLow)) * -100; end |

- Plot the Williams %R values on a chart to visualize overbought and oversold conditions. You can use the plot function to create a line chart of the Williams %R values over time:

1 2 3 4 |
plot(1:days, WilliamsR); xlabel('Day'); ylabel('Williams %R'); title('Williams %R Indicator'); |

By following these steps, you can calculate and visualize Williams %R using MATLAB for any stock or asset with historical price data.

You can run this MATLAB code with your actual historical price data to calculate and visualize the Williams %R indicator for any stock or asset. Make sure to adjust the length of the historical data window and customize the plot as needed based on your analysis requirements.
