The chart below is a daily bar chart of the S&P 500 from the December 27 2018 market lows. Note first that the price bars did not retrace enough at any point in the rally to touch the channel and generate a Buy signal, and second, that if going forward from here price falls to the price channel either prices will find support and generate a Buy signal, or, the channel fails and the market resumes its long-term downtrend began in Oct, 2018.
Next update Friday.
