Weinstein stage indicator
I would like to implement the Weinstein stage indicator that classifies stock into 4 stages.
Here is one online tool that has this indicator: https://www.chartmill.com/documentation/technical-analysis-indicators/92-Weinstein-stage-analysis-in-chartmill
Can you give me a few pointers on how to implement it in BackTrader? Is it just based on a 30 period MA or something else?
