How is it possible to code Simple Moving Avergae of exprassion? Is it possible to do it in 1 line like this Average((Close+Low+High-Open)/2)or should I make ALL calculation by hand? Please help ASAP.

[youngtrader]

Also I need the following indicators:
1) BollingerBands of (high - open)
2) BollingerBands of abs(open - close)
3) BollingerBands of (close - low)
How is it possible to code? Could you provide me these formulas.
Thank you very much.

Hi Alex,

if it possible tell me the code or tell me how to code it with formula
wizard this simple formula:

BollingerBands of (high - open)

without re-writing the Bollinger Bands code !!!

WAITING FOR YOUR REPLY ! ! !

my best,

Young

Contrary to my original reply, which I pulled the moment I realized you were
using a different input, you cannot do that with Formula Wizard

Hi Young,

I think it's impossible to write BollingerBands(high - open) as is, but try to use the following solution to not modify BollingerBands formula every time:

function main(Length) {
	if(Length == null)
		Length = 20;
	BBArray = new Array();
	for(i = 0; i < Length; i++)
		BBArray[i] = (high(-i) - open(-i));

	return new Array(BollingerBands(BBArray,Length,Top=1),BollingerBands(BBArray,Length,Bot=-1));
}

function BollingerBands(Array,Length,Type) {
	if(Length == null)
		Length = 55;
	if(StdDev == null)
		StdDev = .5;
		
	var i;
	var vSum = 0.0;
	var BBTop;
	var BBBot;
	var SumSqr = 0;
	var StdDev = 0;

	for(i = 0; i < Length; i++)
        	vSum += Array[i];

	if(Length != 0)
		for(i = 0; i < Length; i++)
			SumSqr += (Array[i] - vSum / Length) * (Array[i] - vSum / Length);
	StdDev = Math.sqrt(SumSqr / Length);
	BBTop = vSum / Length + StdDev * StdDev;
	BBBot = vSum / Length - StdDev * StdDev;
	if(Type == 1)
		return BBTop;
	else if(Type == -1)
		return BBBot;
}

If you have any further questions or require additional assistance please let me know.

Regards,
Andy
