Sorry, have removed Photobucket site link. Chart only is a bit clearer.
Chart 1
Not sure if this is something to get excited about.
First chart shows last 6 times Bollinger bands have converged (since Nov 09) the SP has blipped up.
Next chart is a bit larger shows MACD crossed up through MACD Signal line, a possible buy sign a few days ago, and a change the SP will test the 45d EMA.
