Is there a function that will translate price value to hard money value..

[gguindon]

I was wondering if there was a function that would translate price value to hard money such that you could track (for instance) 2% of account equity...say as a moving horizontal line that would move in tandem of the H+L/2 of the current bar on the current chart. So you would have to update the script (daily?) with your account equity as it ebbs and flows but you could have this line that would follow the price action a given % distance away from it - giving you a 'visual' sense of risk.

Is there such an animal?

Any help is much appreciated,

Nope. Not that I'm aware of. You have to build your own.

I'm posting some functions to help you out. This set of code allows you to create a file in the FormulaOutput folder where you can setup symbols and have it automatically load specific values depeneding on the esignal symbol.

Thus, you could load MINTICK & DOLLARPERPOINT values for any symbol and calculate your own net values from these.

var      MTSSymbol = tsymbol;  
var     MTSExchange = "SMART";
var     MTSExpiration = "";
var     MTSType = "stock";
var     MTSDollarMult = 1;
var     MTSMinTick = 0.01;
var     HiddenOrder = 0;
var     FAAccount = ""; 
var     FAGroup = "";  
var     FAProfile = "";
var     FAMethod = "";
var     FAPercentage = "";
var     IBCurrency = "USD";
var              Rnd2 = 0.01;

var bInit = false;

function main() {

  if (!bInit ) {

    setupMTSVars() ;
    debugPrintln(" Symbol Setup MinTick"+MTSMinTick +" Rnd2"+Rnd2+" PointValue"+MTSDollarMult  );
    bInit = true;
  }

}




function setupMTSVars() {
var line = "";
var PosCount;
var tsymbol = null;
  tsymbol = getSymbol();
   PosCount = tsymbol.split(" ");
    if (PosCount[0]) { tsymbol = PosCount[0]; }


//  Default all setting to US STOCKS with IB.
//     debugPrintln("PRE SETUP VARS "+tsymbol);
     MTSSymbol = tsymbol;  
     MTSExchange = "SMART";
     MTSExpiration = "";
     MTSType = "stock";
     MTSDollarMult = 1;
     MTSMinTick = 0.01;
     HiddenOrder = 0;
     FAAccount = ""; 
     FAGroup = "";  
     FAProfile = "";
     FAMethod = "";
     FAPercentage = "";
     IBCurrency = "USD";

    var f = new File("MENT_CT/MTSSymbolDef.CT");
    if (f.exists()) {
      f.open("rt");
      while (!f.eof()) {
        line = f.readln();
        if (line) {
           PosCount = line.split(",");
//           debugPrintln("Checking Symbol :"+PosCount[0]);
           if ((tsymbol == PosCount[0])) {  //  Found Symbol
             debugPrintln("Symbol Found "+tsymbol);
             DefaultContracts = parseFloat(PosCount[1]);
             MTSSymbol = PosCount[2];  
             MTSExchange = PosCount[3];
             MTSExpiration = PosCount[4];
             MTSType = PosCount[5];
             MTSDollarMult = parseFloat(PosCount[6]);
             MTSMinTick = parseFloat(PosCount[7]);
             IBCurrency = PosCount[8];
             Rnd2 = parseFloat(PosCount[9]);
//             HiddenOrder = 0;
/*             FAAccount = ""; 
             FAGroup = "";  
             FAProfile = "";
             FAMethod = "";
             FAPercentage = "";*/
           }
        }
      }
      f.close();
    } 

}


function RndQTR(Direction, Price, Offset) {

  var Whole = Math.floor(Price);
  var Fraction = Price-Whole;

 if (Rnd2 == 0.25) {
  if (Direction > 0) {
    if (Fraction > 0.76) {  Fraction = 1.0; 
    } else if (Fraction > 0.51) {  Fraction = 0.75; 
    } else if (Fraction > 0.26) {  Fraction = 0.5; 
    } else if (Fraction >= 0.0) {  Fraction = 0.25;  }
   return ((Whole+Fraction)+Offset);
  }
  if (Direction < 0) {
    if (Fraction < 0.24) {  Fraction = 0.0; 
    } else if (Fraction < 0.49) {  Fraction = 0.25; 
    } else if (Fraction < 0.74) {  Fraction = 0.5; 
    } else if (Fraction <= 0.99) {  Fraction = 0.75;  }
   return ((Whole+Fraction)+Offset);
  }

 } else if (Rnd2 == 1.0) {
  if (Direction > 0) {
    return ((Whole+1)+Offset);
  }
  if (Direction < 0) {
    return ((Whole)+Offset);
  }

 } else if (Rnd2 == 0.1) {
  if (Direction > 0) {
    Fraction = Math.floor( ((Fraction + 0.05)*10) ) /10 ; 
   return ((Whole+Fraction)+Offset);
  }
  if (Direction < 0) {
    Fraction = Math.floor( ((Fraction - 0.05)*10) ) /10 ; 
   return ((Whole+Fraction)+Offset);
  }    
 } else {
   return Price;
 }
} 

I'll attach the data file in another post.

Here is the Data file. In the code, it has to be stored in the C:\programfiles\esignal\formulaoutput\MENT_CT folder.

Thanks Doji,

Where are the Direction and Offset parameters of the RndQTR function getting their values from?

I'm successfully sourcing the data file...very cool.

[Doji3333]

Direction and offset are passed with each call to the function. These allow you to round up/down and include a positive or negative offset value.

Have fun.

[gguindon]

Doji - thanks for all your help thus far...I would not have come up with this stuff on my own (no doubt)...if I could bug you with just a couple of more questions...

Would you send along an example call to your function?:

function RndQTR(Direction, Price, Offset)

I'm not quite clear on what a negative 'Offset' parameter would look like. And 'Direction' - is that just a positive or negative integer (i.e. +1 or -1) - see your latest reply to the thread.

I apologize for all the questions...I always get turned around when trying to figure the math of points to dollars.

To that end...in your opinion - was this function (RndQTR) meant to account for the figuring of the real dollar values for all futures/commodities or were you thinking specifically of S&P 500? I mean as is...would it be capable of accurately figuring the dollar value of something like Bonds or T-Bills?...as long as the point value and dollar values were correctly entered into the supporting *.ct file?

Any help is greatly greatly appreciated,

Best,

gg

I grabbed this out of one of my projects. You can alter it all you like to address different symbols and rounding needs.

The variable "Rnd2" originates from the symbol definition file and is use to determine how to round a price value.

I use this for all order functions, mouse click functions and generally anything that can product a "non-valid" price value.

Good luck.
