This is an Enhanced version of the standard MACD Indicator.
It displays the MACD Histogram as a normalized oscillator for a better visual representation (With values between -100 to 100)
On the top we have the WaveTrend indicator, showing the general trend of an asset (4 Color codings)
On 0 line, with red and yellow circles, is displayed the Contraption (or so-called Squeeze) of the price action. When these circles appear a major shift in trend is expected.
On the bottom, we have another set of circles, which measure the price compression - These signal a period of very low price volatility.
