How To Calculate Williams %R in Perl?

@garnet.barrows 

Williams %R is a technical analysis indicator that measures overbought or oversold conditions of a security. In Perl, you can calculate Williams %R using the following steps:

1. Define variables for the high, low, and close prices of the security.
2. Calculate the highest high and lowest low prices over a specified period (usually 14 days).
3. Calculate the Williams %R value using the formula:

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

Here is a sample Perl code to calculate Williams %R for a security:

use List::Util qw(max min);

# Define high, low, and close prices
my @high_prices = (50, 55, 60, 65, 70, 75, 80, 85, 90, 95);
my @low_prices = (40, 45, 50, 55, 60, 65, 70, 75, 80, 85);
my @close_prices = (45, 50, 55, 60, 65, 70, 75, 80, 85, 90);

# Calculate highest high and lowest low prices
my $highest_high = max @high_prices;
my $lowest_low = min @low_prices;

# Calculate Williams %R for the last close price
my $close = $close_prices[-1];
my $williams_r = (($highest_high - $close) / ($highest_high - $lowest_low)) * -100;

print "Williams %R: $williams_r
";

You can modify the code to use actual price data for a security and adjust the period for calculating the highest high and lowest low prices.
