Created a gist for filtering the most traded stocks according to their price.

filter.js

//Works only on "http://money.rediff.com/companies/most-traded/nse"
//Used for filtering stocks according to the current price.

var array = document.querySelector('.dataTable').children[1].children.length; //All the stocks displayed on the webpage.

var lowerLimit = 100;

var upperLimit = 200;

for (var i = 0; i < array; i++) {
  var currentPrice = parseFloat(document.querySelector('.dataTable').children[1].children[i].children[1].innerText);
  //Current Price Of every Stock.
  
  if (currentPrice > lowerLimit && currentPrice < upperLimit) {
    document.querySelector('.dataTable').children[1].children[i].style.background = 'black';
    document.querySelector('.dataTable').children[1].children[i].style.color = 'white';
  }
}
