they read it by peaks (or valleys) on the near-term line as it matches up with price action, just like a macd.
the concept is price and the near-term line (shown as blue line below) are diverging or converging. There is a signal people use with it called the near-term divergence which works similar to the macd divergence. the 3 lines indicate 3 separate time frames: intermediate line = 1–3 months, near-term line = 5–15 days, and momentum line = 1–5 days and tend to indicate oversold or overbought levels. It has 3 lines that oscillate between 0 and 100.
