That wasn't a journal; that was a thread somewhere. Not relevant now that ranges are so much more constricted.
There are all kinds of oscillators you can use: DMI, Chaikin, CCI, stochastics, RSI, MACD histogram, etc. If you do not now use an oscillator, plot several under your chart (use stockcharts.com if you don't have your own software) and see which tell you what you want to know when (or preferably before) you want to know it. Then fiddle with the settings for whatever you select. These may - and probably will - vary according to the bar interval you use.
