Could we have known that this stock might run into resistance at $26.68 (3)? Yes - If we calculated a Fibonacci extension ahead of time.
Take the difference in price between 1 and 2. In this case: $25.92 - $23.11 = $2.81
Now take that difference, $2.81 and multiply it by 1.272. $2.81 x 1.272 = $3.57
Now add $3.57 to $23.11 (2) and you get...
$26.68 - the exact high at 3. That is the Fibonacci extension.
In the second example...
$28.75 - $25.00 = $3.75 x 1.272 = $4.77 + $25.00 = $29.77. We are off by three cents here.
So, if you buy pullbacks and you are wanting to take partial profits on a stock, you can calculate this ahead of time.
Note: The two common Fibonacci ratios used for calculating extensions are 1.618 and 1.272. There are others but these seem to work the best.
Sometimes the 1.272 and 1.618 extension levels seems close to Ninjas 38,2% and 50% extensions depending on where you put point A of A-B-C. The two point version share only point B and C.
If I add 123,6% and 161,8% to Ninjas simple 2-point fib retracements and measure the same last retracement BC itīs getting even closer to the 2-point extension version. But Iīm not sure if its the same thing.
Compared to koganam I would say: The Fibonacci retracement will make measures of BC, using AB as a reference, while the Fibonacci extension will make measures of CD, using BC as a reference. And the Ninjatrader version measure CD by using ABC as a reference.
