another handy tool...

I like the Summation Index because it dosn't zig and zag too much and gives pretty good signals that the trend has changed at least in the intermediate time frame. I scribbled on the chart below trying to focus on those points where the Summation index made a turn and how the market price levels correlated to it. I read this as a confirming signal that it is time for the market to come back home to it's 200 day moving average...
