An oscillator form of the crossover system that was recommended by Mark Jurik. The oscillator is based on the Jurik Moving Average (JMA) and Double Weighted Moving Average (DWMA) convergence/divergence. I use the best original JMA' clone on TradingView https://www.tradingview.com/script/714vYiDe-Jurik-Moving-Average/ that has the almost identical behaviour as the original one.
I made it more pretty and added alerts for the peaks (blue circles).
As Mr. Jurik noticed: "Of all the different combinations of moving average filters to use for a MACD oscillator, we prefer using the JMA - DWMA combination."
