Short is the preferred trading strategy with 65% chance of being right. The trend sentiment plus market sentiment (moving force) is negative, and market sentiment change is negative. The price level is not too low. Wait action is recommended in three scenarios with either high uncertainty or high risk: 1. The trend sentiment and market sentiment are at the opposite directions. 2. Both trend sentiment and market sentiment are positive, but the price level is elevated. 3. Both trend sentiment and market sentiment are negative, but the price level is depressed. In an uptrend, as an investor, you may want to wait for the pullback to open long position. In a downtrend, the price will likely rebound after huge decline. As an investor, you may want to wait for the rebound to exit long position.
Market sentiment will accelerate the current trend when both trend sentiment and market sentiment are at the same direction. Market sentiment will generate volatility when it's at the opposite direction of the trend sentiment. News sentiment measures the daily emotion of the market. News sentiment may impact the daily price change while market sentiment is a more stable and consistent moving force.
