The most recommended one: take the 9-day periodic line as an example, and the calculation formula of rsv in the last 9 days is: 9-day RSV =(9-day closing price -9-day lowest price) /(9-day highest price -9-day lowest price) * 100.
Recommended reason:
? Kdj index image is formed on the basis of rsv No.9; In fact, kdj values are tracking rsv. In the downward trend, the rsv value tends to 0, and in the upward trend, the rsv value gradually approaches 100. Then, when a sideways trend is formed in the continuous upward or downward trend, can the kdj value turn to 50?
