Best things in life are free, like sex. Anyway, here is the free chart from Bigcharts.com.
You will notice, that the first sell signal was a bit early, and the market went like 10 points against it, but there was a confirmation second signal. That was rewarded by a nice 50 points drop and again another buy signal with a 40 points rebounce. That was very quick so there was signifficant slipage, but still...
Now on my Ameritrade 10 min chart it gave a sell signal where I put a questionmark here giving another 30 points drop. The moral is that one should use more than just one charts.
But still, as free charts go, this is one helluva indicator.
Right now we have another buy signal....
