Accessing values of Studies in Previous Bars

[mberger02]

Good Day.

I am totally new to EFS, just started writing a script based on the strRSI.efs

I want to use the values of RSI for the previous bar, and bars before, how do write code to do that?

Also, how can I write values etc to a text file so I can debug & test?

I am also looking to implement STOP and LIMIT exits - can I store the entry price so that I can put stops at specific values away from the entry price?

Please direct me to examples and areas in the manuals where I can get this info.

Thanks,

DB

WELCOME TO THE JUNGLE!

I'll start by answering your question because I know how frustrating this is!

From the Knowledgebase:

To Create a Series 

var myStudy = null; 
var bInit = false; 

function main() { 
var myVar; 

   if ( bInit == false ) { 
       
      myStudy = rsi( 14 ); 
      bInit = true; 

   } 

   //retrieve the current value 
   myVar = myStudy.getValue(0); 

   return( myVar ); 

} 

So you can now do this:

RSI_this_bar = myStudy.getValue(0);   

RSI_1_bar_ago = myStudy.getValue(-1);   

RSI_2_bars_ago = myStudy.getValue(-2); 

MAY ALL YOUR FILLS BE COMPLETE.
