To calculate Fibonacci extensions using TypeScript, you can follow these steps:

  1. Create a TypeScript function that calculates the Fibonacci sequence up to a specified number of terms. You can use a loop or recursion for this task.

function fibonacci(n: number): number[] {
  let fibonacciSequence: number[] = [0, 1];
  
  for (let i = 2; i < n; i++) {
    fibonacciSequence[i] = fibonacciSequence[i - 1] + fibonacciSequence[i - 2];
  }
  
  return fibonacciSequence;
}


  1. Use the Fibonacci sequence generated in step 1 to calculate the Fibonacci extensions for a given price level. The Fibonacci extensions are commonly calculated at 161.8%, 261.8%, and 423.6%.

function fibonacciExtensions(price: number): number[] {
  const fibSequence = fibonacci(15);
  const extensionLevels = [0, 0.618, 1, 1.618, 2.618, 4.236];
  const extensions: number[] = [];

  for (let i = 0; i < extensionLevels.length; i++) {
    extensions.push(price * extensionLevels[i]);
  }

  return extensions;
}


  1. Finally, call the fibonacciExtensions function with a specified price level to calculate the Fibonacci extensions.

const price = 100;
const extensions = fibonacciExtensions(price);
console.log(extensions);


This will output an array of Fibonacci extensions for the given price level.
