These have been optimized for the cryptocurrency markets, but also seems to work really well in commodities, futures, and forex. A crossover with the closing is treated as a buy or sell signal. The 4 lines provided have different sensitivities and therefore can be treated in combination or separately. This seems to be highly effective in trending markets as a trend follower, and in a ranging market the signals can pretty reliably be reversed for profit. I made this code private because it is still a work in progress and I am interested in hearing people's thoughts and experiences with it for further developments. This is well on the way to becoming a holy grail!
All the best, happy trading
