Guys, the previous and your post here, I try to use the KDJ script 3 of them all showing different value in the J line. BECAREFUL on the wrong code.
I found this on the original thinkorswim website, the TOS script original script provided by TDAmeritrade , you can click to import.

input KPeriod = 9;

def lowest_k = Lowest(priceL, KPeriod);
def c1 = priceC - lowest_k;
def c2 = Highest(priceH, KPeriod) - lowest_k;
def FastK = if c2 != 0 then c1 / c2 * 100 else 0;

plot FullK = MovingAverage(averageType, FastK, slowing_period);
plot FullD = MovingAverage(averageType, FullK, DPeriod);

Hi, I wrote another version of KDJ indicator which based on difference sequence & linear combination insdead. The definition of RSV is exactly the same, the initial value of K and D is 50, insread of moving average, K(i)=((kPeriod-1)/kPeriod)*K(i-1)+(1/kPeriod)*RSV(i), the calculation of D(i) is similar, J=3*K-2*D. This calculation method is exactly the same as the KDJ indicator provided by many Asian brokerages like webull(微牛) and Futu(富途).

oh my god! you save my life! this is exactly I want and the same as the XQ Taiwan APPS, I been looking for this for long time, I was using the TD script and all other post here for the script all wrong value. THIS IS LIFE SAVING! I hope they don't use the wrong code for the KDJ!

BECAREFUL GUYS I lost money cause of the WRONG KDJ script - the J -value, please pay attention.

I compare the AXSM - 5 min chart, - 3/14/2022/ 3:55PM , last candle bar! J value is 103% in XQ APPS, and your code in TD showing the same 103%

[LLP]

Can someone please make this KDJ calculation into think script?

Calculation formula

RSV=(CLOSE-LLV(lOW,N1))/(HHV(HIGH,N1)-LLV(LOW,N1))*100

K=MA(RSV, N2)

D=MA(K,N3)

J=3*K-2*D

Where N1=9, N2=3, N3=3

The K and D values ??are always between 0 and 1.

The RSV in the KD line varies with the high and low prices on the 9th and the closing price. If the market is a clear uptrend, it will drive the K line (fast average) and the D line (slow average) to rise. However, if the rally starts to slow down, it will slowly react to the K and D values, causing the K line to fall below the D line, at which point the short-term downtrend is established. Since the KD line is essentially a concept of random fluctuations, it is very correct for the short- and medium-term market.

By default, the system draws three lines on the sub-picture, which are the three-day average line K of the RSV value, the three-day average line D of the K value, and the J line obtained by subtracting twice the value of D from the K value.

Application rule

1.When the D% value is above 70, the market is overbought. When the D% value is below 30, the market is oversold.

2.When the inclination of the K% line tends to be gentle, it is a warning signal.

3.When the K% value is greater than the D% value, it shows that the current trend is rising, so when the K% breaks through the D% line on the graph, it is the buy signal.

4.When the D% value is greater than the K% value, it shows that the current trend is to fall, so the K% in the graph falls below the D% line, which is the sell signal.

5.The intersection of the K% line and the D% line must be below 80, and the signal below 20 is more correct. The K% and D% lines are the same as the strength and weakness indicators. When the K% value and the D% value are above 70, the overbought phenomenon has been shown, and oversold phenomenon occurs below 30%. Only the strong and weak indicators can not clearly show the timing of buying and selling, and the KD line can achieve this goal.

6.When the deviation signal is generated, it is also a very correct time to buy and sell.

7.The circulation is too small, the stocks with too small trading volume are not suitable for KD indicators; the weighted index and the hot large stocks are extremely accurate.

8.When the KD value crosses around 50 and is the board, this indicator cannot be regarded as an obvious trading signal.

9.J%>100 is overbought, J%<10 is oversold, and the response is faster than K% and D%. The KD indicator is a settable calculation period (ie, n value) obtained by calculating the purchase and sale over n days, plus the average line concept, and P1, P2, and P3 values. Generally, P1 and P2 are set to 3. If P3 is set to 0, it means that the J line is not drawn.

Also this calculation please:

RSV:=(CLOSE-LLV(LOW,P1))/(HHV(HIGH,P1)-LLV(LOW,P1))*100;

K:SMA(RSV,P2,1),COLORFF8D1E;

D:SMA(K,P3,1),COLOR0CAEE6;

J:3*K-2*D,COLORE970DC;

The canned response from ToS support would be that scripts used in the scan hacker should only contain that logic required to define the filter.
