In the S&P 500 the Yearly High and Low shows the trend strength of the market in total. The green line shows the number of companies with new yearly highs per day and the blue line shows the lows. Now if you combine that information with the S&P 500, you can see that every Yearly-High low value is followed by a Market upward move a few days later. This is an excellent indicator to get in the S&P ETF or Future market and leave it, when the highs are falling down again. The idea comes from splitting the advance/decline line in long and short part and watch the long positions to rebuild every few days/weeks.
Comment:
in the indicator above we have two lines: green means "number of companies with 52 week highs" and blue means "number of companies with 52 week lows"; both indicators have peaks; the green peak means: sell SPX or ESmini, while the blue peak means: buy SPX or ESmini; they are contra indicators showing entries and exits into the S&P market
