说它是健康,因为是牛市的调整
Arms Index/TRIN: developed by technician Richard Arms in the 1970s, relates daily advances and declines to daily upside/downside volume.
For the long-term analysis, using an 89 day moving average, as Mr. Arms suggests. The general rule-of-thumb for interpreting the chart are that readings below 1.0 are considered extremely bullish and warn of overbought conditions.
