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.

// maximum deviation EMA

	if (MaxDev > 0.0) {
		pctdev = 100.0*(ci - last_avgema)/ci;
    	if (pctdev >= 0.0)
    	{
        	if (pctdev > MaxDev)

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.
