Current Bar Wierdness

[ronblack]

I am new to writing code in JavaScript. On my first efs studies, the lines plot correctly, except for the current bar. They are essentially exp. moving averages. As the ticks accumulate on the current bar the line moves up into the current bar's value.

How can I prevent this? Thanks, Ron

Here is the calculation portion of the code:

function main() {

//Check for initial null values
if (nn == null) {

nn = 1;
Osc1_1=(high(0)+low(0))/2
Osc2_1=(high(0)+low(0))/2
Osc3_1=(high(0)+low(0))/2
Osc3_2=(high(0)+low(0))/2
Osc3_3=(high(0)+low(0))/2
Osc3_4=(high(0)+low(0))/2
Osc4_1=(high(0)+low(0))/2
Osc4_2=(high(0)+low(0))/2
Osc4_3=(high(0)+low(0))/2
Osc4_4=(high(0)+low(0))/2
}


// If we are past the first bar, store away current osc values as prev values, calc new osc values

if (nn>=1){

Osc1=(0.53*Osc1_1)+(0.47*close(0));
Osc2=(0.53*Osc2_1)+(0.47*Osc1);
Osc1_1=Osc1;
Osc2_1=Osc2;



}

nn++

return (Osc2);

}

your issue is

with historical (past bar data) vs. realtime (tick-by-tick) data...

What you need to do is create two routines in your code..

the first handles the past bar data (just as you have done now).

the second handles the RT data and needs to inlcude a funtion to test for a new bar, then run your calcs on the previous bars data and continue like this.

here is a simple example..

var nLastRawTime = 0;
var BLBarOffset = 0;

  var vHour;
  var vMin;
  var vSec;
  var vDay;
  var vMonth;

function main() {


  var vTime = new Date();
//---------------------------------------------------
//  Get Time Variables 
  vTime = getValue("Time", 0);
  vHour = vTime.getHours();
  vMin = vTime.getMinutes();
  vSec = vTime.getSeconds();
  vDay = vTime.getDate();
  vMonth = vTime.getMonth() +1;

if (getCurrentbarIndex() != 0) {
  // past bars...
..  do your stuff here

}
if (getCurrentbarIndex() == 0) {
  // RT ticks...
  //-------------------------------------
  //  check for new day
 if (getValue("rawtime", 0) != nLastRawTime) {
     nLastRawTime = getValue("rawtime", 0);
     BLBarOffset += 1;


..  do your stuff here

  } // end if new bar

}
