This chart is useful to study how the Ichimoku System, MACD, & the RSI works to determine price movement/trend (basically)... This chart also goes on to show how all 3 indicators can work together/correlates (in a consistent orderly/manner) to forecast/predict the market price movement/pattern/trend...
The MACD certainly correlates/coordinates very well with both the Ichimoku & the RSI... Together, they should be powerful/indispensable to determine/predict the market price movement...
