The Coppock indicator is available on Stockcharts. In its original form it used monthly data, and for that you need a subscription. The Wikipedia article on the signal offers this helpful hack:

Although designed for monthly use, a daily calculation over the same period can be made, converting the periods to 294-day and 231-day rate of changes, and a 210-day weighted moving average.

I have not used the Coppock indicator, which was designed to identified buys only (though there is an implied sell signal built into it). It occurs to me that it might be useful in connection with something I do from time to time: add money to an LTBH cash account in which sells are exceedingly rare.
