Exponential formula for finding access to KDJ

According to the following formula, write k, d, j in the above parameter part, and then write the interval.

To make some suggestions, I personally summed up KDJ for so many years. First of all, I changed the three parameters to 30.3.3, which can be used as medium-term indicators. Then, KDJ is not suitable as a stock index. Third, judging the market is more accurate than judging individual stocks.

I wish the landlord a smooth investment.

RSV=(CLOSE-LLV (low, N))/(HHV (high, N)-LLV (low, n)) *100;

a=SMA(RSV，M 1， 1)；

b=SMA(a，M2， 1)；

e = 3 * a-2 * b；

If (a & lt0)a = 0；;

If (a>100) a =100;

IF(b & lt； 0)b = 0；

If (b>100) b =100;

If (e & lt0)e = 0；;

If (e>100) e =100;

k:a；

d:b；

j:e；
