This is an exponential moving average which adjusts its self to maintain a minimum percentage deviation from the last close. This allows you to use slower moving averages to better smooth price without having to wait excessively long for a signal to occur when price reverses.

Of course you could use of variety of ema based averages rather than the standard ema used here.

Indicator / Formula

Copy & Paste Friendly
// maximum deviation EMA
Per = Param("EMA Period", 22, 1, 900, 1);
MaxDev = Param("Max Deviation", 1.0, 0.0, 99.0);
alpha = 2.0/(1.0 + Per);
one_minus_alpha = 1.0 - alpha;
last_avgema = C[0];
avgema[0] = last_avgema;
for (i=1; i<BarCount; i++)
{
	ci = C[i];
	last_avgema = alpha*ci + one_minus_alpha*last_avgema;
	if (MaxDev > 0.0) {
		pctdev = 100.0*(ci - last_avgema)/ci;
    	if (pctdev >= 0.0)
    	{
        	if (pctdev > MaxDev)
            	last_avgema = ci - .01*MaxDev*ci;
    	}
    	else
    	{
        	if (-pctdev > MaxDev)
            	last_avgema = ci + .01*MaxDev*ci;
    	}
	}
	avgema[i] = last_avgema;
}

if u r really interested to see any result of this code then u need to use the value of MaxDev <=1. above one it wont produce any different results than tht off normal MA.
so plz change the line 2 of code with

MaxDev = Param(“Max Deviation”, 0.5, 0, 1,0.0001);

You are correct that a value of 0 results in a standard ema. However, I specifically left 0 as a possible value, so that when optimizing, one of the possibilities is a standard ema.
