Is this something worth looking into?

Look at the 4 hr chart.
First you decide the trend. I am using an indicator Synergy_APB( found it on FF)

Draw a Fibo retracement on 4 hr bar.

Put sell/buy limit order at 50 % retracement.

TP would be at 161.8% extension. Stop loss at 0%.

Here is another chart

Is it possible to have price showing at fibo lines?

another chart

When price does not retrace 50%, the next bar does not seem to have too much momentum in the same direction.
Does this suggest possible end of trend?

Yes, just add %$ to the description field inside the fibo properties.

Thanks Psymantis
