@PatriceB, you will find @TheShadowFiend 's Link very helpful. This kind of TA uses 4 legs (starts with an impulse leg, price action) fibonacci level in relation to each other. You can use this technique to determine potential reversal zones.
@PatriceB, do you think it would be easier to comprehend, if you would see the different Fibonacci tools on the chart? I like charts more clean, so im used to remove the measurement tools before publishing
