Just read the MT4 manual .... and is seems this is the standard way to calculate Parabolic Sell and reverse. So question is ... is this a good system?


From the manual ...
double iSAR(string symbol, int timeframe, double step, double maximum, int shift)
Calculates the Parabolic Sell and Reverse system and returns its value.

Parameters
symbol - Symbol the data of which should be used to calculate indicator. NULL means the current symbol.
timeframe - Time frame. It can be any of Time frame enumeration values.
step - Increment, usually 0.02.
maximum - Maximum value, usually 0.2.
shift - Shift relative to the current bar (number of periods back), where the data should be taken from.
Sample
if(iSAR(NULL,0,0.02,0.2,0)>Close[0]) return(0);
