Help Understanding This Code

[ephi144 10]

i want to use the following code in my indicator.

however, i cannot read it correctly as what its doing.

i am an ok TS programmer. i have my own indictor that i am working on.

i want to integrate the following code so that it only draws the buy or sell lines when i am long or short.

 

right now it works completly independent of my code. please help!

 

 

 

 

{Type : Indicator, Name : Variable Volatility Stops}

 

INPUT: LENGTH (21), CONST(3.05);

 

vaR: SWITCH(1), TR(0), ARC(0), SAR(0),HISIC(0),LOSIC(0);

 

TR= VOLATILITY (LENGTH);

ARC= TR* CONST;

IF CURRENTbar = length then begin

hisic=c;

losic=c;

if h>= xaverage (h,length-1) [1] then begin

hisic= highest(c,length);

Sar=hisic-arc;

switch= 1;

end;

if l <= xaverage (l,length-1) [1] then begin

losic= lowest (c,length);

sar = losic +arc;

switch=0;

end;

end;

 

if switch =1 then begin

if c>hisic then hisic=c;

sar=hisic - arc;

if c< sar then begin

switch=0;

losic=c;

sar = losic + arc;

end;

 

end;

if switch=0 then begin

if c< losic then losic=c;

sar= losic +arc;

if c> sar then begin

switch=1;

hisic=c;

saR=HISIC- ARC;

END;

END;

 

IF C > SAR { AND C[1] < SAR } THEN

 

Plot1(SAR,"Sell");

 

IF C < SAR { AND C[1] > SAR} THEN

 

Plot2(sar,"Buy");

SWITCH is a reserved word. You cannot use it as a variable.

[ephi144 10]

yeah but it still works. nonetheless, i think might have it figured out.

I don't understand what you need.

[thrunner 10]

Use the TS I_MarketPosition (Reserved Word) to show volatility stop only when a position is in the market. Strategy not included, code can be verified as indicator or showme.

 

I_MarketPosition can only be used in a study.

 

I_MarketPosition will only return a value if a strategy is applied to the same data.

 

inputs:  
    ATRLength( 10 ) ,  
    NumATRs( 3 ) ; 

variables:  
    ATRCalc( 0 ),  
    MP( 0 ),  
    PosHigh( 0 ),  
    PosLow( 0 ) ; 

ATRCalc = AvgTrueRange( ATRLength ) * NumATRs ; 
MP = I_MarketPosition ; 

if MP > 0 then 
    begin 
    if MP[1] <> 1 or High > PosHigh then  
         PosHigh = High ;  
    Plot1( PosHigh - ATRCalc, "Plot1" ) ; 
    end   
else 
    if MP < 0 then  
         begin 
         if MP[1] <> -1 or Low < PosLow then  
              PosLow = Low ; 
         Plot2 (PosLow + ATRCalc, "Plot2"); 
         end ;

hi guys,

 

thank you for helping me. i just wanted to know what the heck the code was doing. i wanted the sar to paint based on my position. if u use the code as an indicator you will see that the it switches to long or short whenever the price closes above the SAR value.

which did not play well within my code.

 

 

i think i have it figured out. as well as therunners help is making much more sense now.

i will try to integrate your code within my strategy today.

however, i have made the following changes. please let me know if the following looks ok to make sure i was understanding the code correctly.

 

 

 

TR= VOLATILITY (VOL_LENGTH);

ARC= TR * VOL_CONST;

IF CURRENTbar = length then begin

HISIC = close;

LOSIC = close;

if high >= xaverage (high,VOL_LENGTH-1) [1] then begin

HISIC = highest(close,VOL_LENGTH);

SAR = HISIC-arc;

SWITCH_IT= 1;

end;

if low <= xaverage (low,VOL_LENGTH-1) [1] then begin

LOSIC = lowest (close,VOL_LENGTH);

SAR = LOSIC + ARC;

SWITCH_IT=0;

end;

end;

 

if SWITCH_IT = 1 then begin

if close >hisic then hisic = close;

SAR = hisic - arc;

if close < SAR and AreWeShort = true then begin

SWITCH_IT = 0;

LOSIC = close;

SAR = LOSIC + ARC;

end;

end;

if SWITCH_IT=0 then begin

if close < losic then losic = close;

SAR = losic +arc;

if close > SAR and AreWeLong = true then begin

SWITCH_IT = 1;

HISIC = close;

SAR = HISIC- ARC;

END;

END;
