New Feature(s):
Allow standard deviation bands around the Signal line. Provided in the example chart is one possible use case of these bands, as an earlier detection of reversals (which, let's face it, default MACD is terrible at, and I really like MACD!). When the MACD line is extended from the Signal line, as it enters back into the extended bands, we may see a drop/reversal. Without having to wait for a very laggy crossover!
I have experimented with Keltner Bands in many different contexts, and my initial thought was of using ATR around the Signal Bands, but, for one, ATR requires OHLC data, where as I'm pretty much just comparing the band with its historical self, so while I am not the biggest fan of the over-responsiveness of standard deviation bands (though, I'm getting a better feel for them), in this case it works out.
I also allow differing colors for the Signal line, rising vs. falling vs. neutral (no change). In a trend following context, the Signal line often gives us a stable view of the trend. And fluctuations in the MACD provide pullback points, so having a clear color-coding of the Signal line can be helpful for visual scans of charts.
Removed Feature(s):
There was an option to show the Rate of Change of the MACD line (instead of the MACD itself). I haven't, thus far, found value in it. Though I had an idea that sudden flicks in the ROC could act as early warnings. But I hope the same intent is now covered via the use of bands around the Signal line and touches of those bands by the MACD line.
Happy and Profitable Trading, everyone.
