As you can see from my analysis, Facebook has been in a strong uptrend for a couple of months now, however I feel this is coming to an end.
Price is appears to be respecting the upper level of the daily channel that is in place. This is strengthened by an which is classed as oversold and a indicator that is showing divergence.
For entry, I would probably drop down to the 4 hour chart and wait for it to break and retest the red support line. I would then ride profits down until it reaches the bottom of the daily channel.
