This crossover system was originally conceptualized by Jurik Research and made public to the world on their website.
The indicator consists of the faster Jurik Moving Average (JMA) and the slower Double Weighted Moving Average (DWMA). A long signal is shown when the JMA line crosses above the DWMA line (indicating a possible reversal in trend). A short signal is shown when the JMA line crosses below the DWMA line. Take profit signals are shown when the JMA line reverses directions. Alerts for signals are included in this indicator.
The default settings are not optimized for any timeframe. Both JMA and DWMA lines are defaulted to hidden.
