How to use Fibonacci Extensions in MT4?

How to use Fibonacci Extensions in MT4? I cant find it at the toolbox .

There is no tool. You have to go into the fib tools properties and add what ever fib level you want

If you can’t see the Fib icon on your toolbar, just right click on any drawing icon already on the toolbar and select “Customize”. Then find “Fibonacci Retracement” in the left hand list and click “Insert”.

The Fib icon will now be on with your drawing tools
