The Natural Directional Combo was created by Jim Sloman as part of his Ocean theory series and I believe this is his final unique formula that I'm publishing to make them all open source. If you know of any others then please send me a message. He passed away at a young age and I want to make sure his legacy lives on. Big thanks to altcoinz and tmac87 for giving me his full source code and materials in order to publish everything. So like my Natural Market Combo script, this essentially take his Natural Stochastic Indicator and his Natural Directional Index to create his own average of both indicators. Like the market combo indicator, I created a fix to address the errors in his original script and included both strong and normal buy and sell signals. Strong signals are darker in color and normal signals are lighter in color. Buy when the line turns green and sell when it turns red.
Let me know if there are any other scripts you would like to see me publish!
