volatility question

[stvchez]

quick question. i have a working volatility function. what I am attempting to do is overlay a Bollinger on this. here's what I have so far. thx.

function calcxVolat(symbol){

var xVolat = ((high(symbol)-low(symbol))/open(symbol))*100;

var vBollingerBands = new

BollingerStudy(20,"close",2);

return xVolat;

}

The section of code you posted is only a function and does not return anything to the chart. If I am not mistaken it is part of an efs (called truth volatility or something similar) that I wrote some time ago. Anyhow you need to add the Bollinger study in the main function of the efs. For the syntax required by the Bollinger study click on the Help button in the Formula Editor or see the EFS2 Function Reference in the EFS KnowledgeBase
