Tradestation's SlowK may not equal to FastD - Help

Tradestation website says, "Stochastics are made up of four individual calculations: FastK, FastD, SlowK, SlowD. The core of the calculations is based upon the FastK value that is calculated in the following manner.
FastK = (C - L)/(H - L)*100… where
L = Lowest Low of a specified period
H = Highest High of a specified period
C = Current bar Close
FastD is a smoothed average of FastK, SlowK is equal to FastD"

I have analyzed the output data on Trade station. In fact SlowK is equal FastK, and is not smoothed average of FastK. Can someone confirm my finding on TS 9.1?

fiverr:

My TradeStation (version 9.5) has two stochastic indicators -- Stochastic-Fast and Stochastic-Slow. Like you said, the FastD is a smoothed average of the FastK in the Stochastic-Fast indicator. When I also plot the Stochastic-Slow indicator, the SlowK there is the same as the FastD in the Stochastic-Fast. So in effect, the SlowD in the Stochastic-Slow indicator is just a smoothed average of the FastD in the Stochastic-Fast. More smoothing but also more delay.

I understand that you observing SlowK = FastD which is correct.

Can you confirm that you can see SlowK = FastK? This is my observation from TS. If you are observing the same phenomenon, then TS has an incorrect implementation.

No, SlowK does not have the same reading (or plot) as FastK on my TradeStation.
If I plot both Stochastic-Fast and Stochastic-Slow on the same indicator sub graph, I see three indicator lines: FastK, FastD (overlapping with SlowK) and SlowD.

Hope that is clear.

What do you mean the "test code"? All I plotted were the standard indicators that came with TradeStation -- Stochastic-Fast and Stochastic-Slow. Standard settings for both -- 14,3,3,1. You can plot both indicators in the same subgraph.
Maybe if you could provide more detail in your question to see if I can understand better?

I am converting this single line of EL code from TS to MT4

LINEARREGVALUE (SLOWK (3), 3, 0);

In my conversion and double checking the data, I found that SlowK is equal FastK, and is not smoothed average of FastK.

This may be the case where the standard indicator that came with TS is correct on its charting. However the implementation of EL code compiler is not correct if you save the output into a text file. This is what I mean by test code.

My TradeStation shows three user-changeable parameters for each of Stochastic-Fast, and Stochastic-Slow. They are: 14,3,3. They are different from what you show above. Also Stochastic calculation has nothing to do with Linear Regression Value (as you implied in your formula above). Since I am not familiar with MT4, I do not offer further comments.

My TS indicator for SLOWK has only two input parameters, so I used SLOWK(3,3). Per your request, I exported ES daily bar data with SLOWK(3,3). See attached .txt file. Hope that helps.
