K line is :
K = ((Current Close – Lowest Low) / (Highest high – Lowest low))* 100

D is simple moving average of the K line. Usually D is 3 day simple moving average of K line but it depends on what trader wants to choose. We have used exponential average.
D = N day simple moving average of K line

‘J’ is the divergence of ‘D’ value from the ‘K’ value.
J = (3*D) – (2*K)

An example of a strategy rules:

Buy – When ‘J’ line crosses above the 50 mark
Sell – When the ‘J’ line crosses below the 50 mark

Thanks very much. It's really useful.
Moreover, seems the J value calculated by the indicator is incorrect. J =3*K-2*D, but in lua file it's 3*D-2K.....

I checked.
The formula is same.

Mq4
percentJ[i] = 3 * percentD[i] - 2 * percentK[i];

Lua
buff_J[period]=3.*buff_D[period]-2.*buff_K[period];

Thanks for reply.
I misunderstand the definition of J value, both of 3K-2D and 3D-2K are okay, and the accuracy of each one depends on market.
Thanks again.

Indicator was revised and updated.

dear apprentice:
the indicator works abnormally. the reason is that the formula given is incorrect. will yoou please revise the indicator again? following this formula:

RSV = ((Current Close – Lowest Low<in 9 periods>) / (Highest high<9> – Lowest low<9>))* 100

K line is 3 periods simple averrage of the RSV data .
K = N day simple moving average of RSV

D line is simple moving average of the K line. Usually D is 3 day simple moving average of K line depends on what trader wants to choose.
D = N day simple moving average of K line

‘J’ line is the divergence of ‘D’ value from the ‘K’ value.
J = (3*K) – (2*D)
