NYSE TICK chart

You've probably seen me post the TICK chart for several different reasons, 1 reason is it acts as a breadth indicator and can be used as a leading indicator intraday for reversals simply by drawing channels and seeing is there's a divergence between the market and the channels on the TICK chart which is the sum of all NYSE stocks ticking up minus those ticking down.

I've put the SPY on the chart in white for reference, note the uptrend channel in the TICK chart is broken and a new downtrend channel has formed.
