Hi. I’ve spent hours trying to convert this code myself, but have a LOT more learning to do. I’ve tried MANY STCs, but the input variables of this one work best for my preferences. It works perfectly as is, however, the only thing I’ve seen different that might be great to add, was a screenshot I included of a protected pine script that appears to change line color at the break of the trend. TOS image below shows variable settings (16,35,5,3,85,17,Wilders) and green indicator line. The pine script image is the red and white indicator line. Again, this one was protected, so I couldn’t get any more detail on it. Thanks, in advance!

___________________________________________________________________________________________

Thinkscript:

input fastLength = 23;
input slowLength = 50;
input KPeriod = 10;
input DPeriod = 3;
input over_bought = 75;
input over_sold = 25;
input averageType = AverageType.EXPONENTIAL;

def macd = MovingAverage(averageType, close, fastLength) – MovingAverage(averageType, close, slowLength);
def fastK1 = FastKCustom(macd, KPeriod);
def fastD1 = MovingAverage(averageType, fastK1, DPeriod);
def fastK2 = FastKCustom(fastD1, KPeriod);
plot STC = MovingAverage(averageType, fastK2, DPeriod);
plot OverBought = over_bought;
plot OverSold = over_sold;

STC.SetDefaultColor(GetColor(8));
OverBought.SetDefaultColor(GetColor(7));
OverSold.SetDefaultColor(GetColor(7));

________________________________________________________________________________________

This is what I found to work with or define FastKCustom:

FastKCustom



FastKCustom ( IDataHolder data , int length );

Default values:

length: 14

Description

Returns values from 0 through 100 depending on a price. If the price is the lowest for the last length bars then 0 is returned. If the price is the highest for the last lengthbars then 100 is returned.

The function is calculated according to the following algorithm:

FastKCustom = if Highest(close, 12) - Lowest(close, 12) > 0 then (close - Lowest(close, 12)) / (Highest(close, 12) - Lowest(close, 12))*100 else 0

Hi,
Did you know that there is a “Schaff Trend Cycle” indicator available in the library…?
https://www.prorealcode.com/prorealtime-indicators/schaff-trend-cycle2/
If this one doesn’t meet your needs, what would you like to change (besides the possible color)…?

Hi. Yes, i did see those. I played with whar limited variables they offered, and they are ver limited by comparison to the TOS version i use. As you can see in my image provided, I able to adjust to an almost exact match to other indicators(I know they use a lot of similar data in their makeup). Being able to adjust the various variables, I am also able to tune out “noise” in the signal. Additionally, the ease of tweaking settings to various timeframes is also critical to my trading preferences. But thank you for pointing that out.

Hi,

Hereby the conversion of the TOS script:

//Settings
fastLength = 23
slowLength = 50
KPeriod = 10
DPeriod = 3
overBought = 75
overSold = 25
AvgType=1 //Exponential Moving Average

// Berekening van de MACD
fastMA = Average[fastLength,1](close)
slowMA = Average[slowLength,1](close)
xmacd = fastMA - slowMA

// STC-calculation
If Highest[KPeriod](xmacd)-Lowest[KPeriod](xmacd)>0 then
fastK1 = (xmacd - Lowest[KPeriod](xmacd)) / (Highest[KPeriod](xmacd) - Lowest[KPeriod](xmacd))*100
else 
fastK1=0
EndIf
fastD1 = Average[DPeriod,1](fastK1)
If Highest[KPeriod](fastD1)-Lowest[KPeriod](fastD1)>0 then
fastK2 = (fastD1 - Lowest[KPeriod](fastD1)) / (Highest[KPeriod](fastD1) - Lowest[KPeriod](fastD1))*100
else
fastK2=0
EndIf
STC = Average[DPeriod,1](fastK2)

// Plotting
RETURN STC AS "STC", overBought AS "OverBought", overSold AS "OverSold"

//Settings

fastLength = 23

slowLength = 50

KPeriod = 10

DPeriod = 3

overBought = 75

overSold = 25

AvgType=1 //Exponential Moving Average

// Berekening van de MACD

fastMA = Average[fastLength,1](close)

slowMA = Average[slowLength,1](close)

xmacd = fastMA - slowMA

// STC-calculation

If Highest[KPeriod](xmacd)-Lowest[KPeriod](xmacd)>0 then

fastK1 = (xmacd - Lowest[KPeriod](xmacd)) / (Highest[KPeriod](xmacd) - Lowest[KPeriod](xmacd))*100

else

fastK1=0

EndIf

fastD1 = Average[DPeriod,1](fastK1)

If Highest[KPeriod](fastD1)-Lowest[KPeriod](fastD1)>0 then

fastK2 = (fastD1 - Lowest[KPeriod](fastD1)) / (Highest[KPeriod](fastD1) - Lowest[KPeriod](fastD1))*100

else

fastK2=0

EndIf

STC = Average[DPeriod,1](fastK2)

// Plotting

RETURN STC AS "STC", overBought AS "OverBought", overSold AS "OverSold"

Is it RocketScalper on the Price ?
Do you have the code of it ?

The Thinkorswim code I pasted above is the code I’m looking to duplicate. I’ve only played with it a few minutes so far, but the code provided by JS above, “with colours”, is about as SUPER close, and the color tweaks are GREAT. Just need to maybe set the variables up to be able to adjust minutely for different time frames and spen a little more time comparing the results.

ALSO: THANK YOU ALL for the help. Your efforts are more than generous, and greatly appreciated.

This is stellar! Thank you! I am working on getting those beginning settings set up as changeable variables. I manually adjusted the settings to match my preferred settings, and they look super close to matching my current use with TOS script. I’m still very green with ProRealCode, so if you get to making those changes to adding the variables before I do, I won’t be upset. 🙂 Thanks again!

When you import the “ITF file” (Indicators), you can then configure the parameters under “Settings”…
