Simple Coding Help - No Promise.

Can someone please post an afl to plot a bar(OHLC) chart from the prices of 2 stocks, A and B?
Something like Oa/Ob, Ha/Hb, La/Lb, Ca/Cb and plot the result. It should be useful for pair trading.
Thanks.
Code:
// Built-in relative performance chart 
_N( TickerList = ParamStr("Tickers", "NIFTY") );  [COLOR="Red"]/// <<<<<<<<<<<<<<< Name of second scrip goes here [/COLOR] 
NumBars = 20; 
fvb = Status("firstvisiblebar"); 
Plot( 100 * ( C - C[ fvb ] ) / C[ fvb ], Name(), colorBlue ); 
for( i = 0; ( symbol = StrExtract( TickerList, i ) ) != ""; i++ ) 
{ 
  fc = Foreign( symbol, "C" ); 

  if( ! IsNull( fc[ 0 ] ) ) 
  { 
     Plot( 100 * ( fc - fc[ fvb ] )/ fc[ fvb ], 
                    symbol, 
          colorLightOrange + ( (2*i) % 15 ),
          styleLine ); 
  } 
} 
PlotGrid( 0, colorYellow ); 
_N( Title = "{{NAME}} - Relative Performance [%]: {{VALUES}}" );
 
New code is also repainting. Can any one confirm ? i think (expandFirst) is culprit ...I am not programmer

Mastermind pls help... :)

ocil, nehal

this code is fine ...
 
k

please use PlotText instead of PlotShape. Also, realize that unlike PlotShape, You will also need to surround plot text with a loop.
can you done in this afl code i m noob :confused:

I'm learning CCI indicator, and I want to predict the strength of CCI. So, Anybody can help me write alf code RSI of CCI and Stochastic of CCI. Tks so much!
Hello,

StochCCI=100*(CCI(14)-LLV(CCI(14),14))/(HHV(CCI(14),14)-LLV(CCI(14),14));
Plot(StochCCI,"StochCCI",1,1);
Plot(80,"",2,1);Plot(20,"",2,1);

Thank you
 
Dear All
How can I get the following values?
1)Highest High of the last 10 bars(HH10)
2)Highest high of the last 30 bars preceding HH10.
3)A buy signal at the next bar or above HH10.
Hello Amit

Giving psedo-code for an idea how to code, try n test it etc. . .

Code:
H10 = HHV(H,10);

H30_10=ref(HHV(H,30),-barssince(H==H10));

Buy = cross(C,ref(H10,-1));
Happy :)
