Blau's Ergodic Candlestick Oscillator = a decent trend finder, however slightly lagged. It can help you to see a reversal entry if you are looking for one. I find the one line ECO hard to use, so I have created this histogram version with a signal line. The colors help to show you whats going on with the ECO and its bias. This indicator shows up in a couple books by people other than Blau, and namely by Krausz. You can also see divergences, for example in pic above the lower or second of the two green humps showing that the general uptrend might be weakened as this run contained less momentum. Tighten up the signal line to see a faster change in its color. These settings are the B3 input settings for default, meaning the ones I use in trading. They are not however the default values you might read about other places.
