To calculate simple moving average and exponential moving average,the following formulaes are being considerred;


SMA=A1+A2+A3+.......An
                            n

where SMA is the simple moving average,A1,A2,A3 the first  ,second and third average while n is the total number of average.


EMAtoday= (valuetoday *(smoothing))+ EMAyesterday*(1-(smoothing))
