 usage
1. When the D indicator is >80, the probability of a retracement is high; when the D indicator is <20, the probability of a rebound is high;
2. When K crosses D upward around 20, it is regarded as a buy signal;
3. When K crosses D downward around 80, it is regarded as a sell signal;
4. When J>100, the stock price is likely to reverse and fall; when J<0, the stock price is likely to reverse and rise;
5. Any signal where KDJ fluctuates around 50 has little effect.
