DTOSC & RSI/ Swami charts

Jazza 
This is probably a new topic. At end of last post regarding Heikin Ashi you mentioned you use 7 period RSI.

Here is an indicator you might want to play around with .  It is DTOSC with RSI.  DTOSC is a Stochastic variation.   I found the code some years ago on a Spanish site in a mixture of Metastock /Spanish description languages.  I translated it ( i think accurately) and added the Bullcharts Fill colours but the code is what it is.  I do not use it as I do not use RSI.  You may have a use for it.

I originally wanted code for DTOSC as Robert MIner uses DTOSC( I think Robert Miner was the author of the DTOSC indicator)  all the time in his book High Probability Trading strategies, Wiley Books, 2009 and I wanted to see what it does.

(Aside:Interestingl;y, in a recent Article in TASC magazine John Ehlers suggests Stochastics and RSI often may not give give similar signals although they should do,  and shows that his his Swami charts method helps to produce similar signals from "Swami" stochastics and RSI).  I understand Metastock language cannot handle the loops needed in Swami charts and therefore I assume Bull script cannot produce Swami charts. IF any one knows hopw to adapt BUllScript to produce Swami Charts I would appreciate it as I use Swami Stochastics on another programe and it is really good).  

Anyway here is the DTOSC and RSI code.

expr := 
expression("Expression");

periods := input("Time periods",14,1);

DiasSto:=input("Stoch periods", 13, 2, 100); 

MA1:=input("MA1 Length", 8, 2, 100); 

MA2:=input("MA2 Length", 8, 2, 100);

U := ma(max(expr - hist(expr,1),0),periods,WILDERS);

D := ma(max(hist(expr,1) - expr,0),periods,WILDERS);

res := 100 - (100/(1 + U/D));

STRSI:= ((100 - (100/(1 + U/D))- LLV( 100 - (100/(1 + U/D)),DiasSto)) / ( HHV(100 - (100/(1 + U/D)),DiasSto) - LLV(100 - (100/(1 + U/D)),DiasSto) ))*100 ;

Sig1:=ma(STRSI,MA1,S); 

Sig2:=ma(Sig1,MA2,S);

[name=RSI]

res;

[name=DTOSC1]

Sig1; 

[name=DTOSC2]

Sig2;

{ Fill }
[name=Fill; linestyle=fill; visible=false]

[color=green] Sig1;

[color=red]  Sig2;

[name=Cross; linestyle=marker; marker=type1; visible=no] [tooltip="DTOSC Signals Cross"]

cross(Sig1,Sig2) or

cross(Sig2,Sig1);

{ Markers }
[name=Dtosccross; linestyle=marker; marker=type1; tooltip="Dtosc"]

cross(sig1,sig2);

[name=Dtosc1cross; linestyle=marker; marker=type2; tooltip="Dtosc1"]

	In his article Introducing Swami charts in the March 2012 Edition of Technical Analysis of Stocks and Commodities, John Ehlers provided Easy Language code for Swami Stochastics. Further to the above post regarding Swami charts, I could not convert that code and the Heat Map into Bullscript. However, I adapted some clever code by Peter in a “Fun with Bullscript “ post from 22 Oct 2004 to adapt Lanes Stochastic Oscillator provided by Bullcharts to produce a range of charted value for the Stochastic. A benefit of using same, maybe showing the results of a range of inputs for %K shows the longer term stochastic as well as the short term which may help a user avoid some usually occurring Stochastic whipsaw signals. Anyway, something else to play around with if you choose to do so. In the chart below I show the normal Stochastic indicator and signals on default settings, in the middle is the adapted coding for a range of stochastic results with original post “Fun with Bullscript” colour scheme. The third indicator is just changing the settings and also the colours in the styles menu.

	Hi cmacdon, Thanks for the DTOSC coding addition and the Swami stochastics. Once again some great coding and new indicator additions. Mucho appreciated

	Jazza Just to clarify. I could not convert Swaqmi chart code to Bullcharts. The variation of stochastics I posted is different. Set out below is a proper Swami Stochastic indicator from another program so you can see the difference. .
