We're reaching the top of a very well-respected parallel channel. This top also aligns with the Fibonacci golden pocket (in yellow), providing extra resistance. Price wicked above the golden pocket, trapping some longs. I'm expecting a reversal to the lower golden pocket (taking profit along the way).
Price and volume are diverging. This is a sign of weakness, as apparently less people are willing to trade at these higher levels. This makes a reversal even more likely.
The horizontal channel is being well-respected. The many touches of this channel validate that the channel is drawn correctly. Price is struggling to break above it, showing weakness.
