Re: [amibroker] Reverse EMA function

["Greg" <gregbean@xxxxxxxxxxx>]

 Hi Dimitris,
 
You say that we can "anticipate" next bar close with this indicator. I'm still trying to learn about TA and I don't know how you would do that. Would you be kind enough to illustrate this. Perhaps with a well known stock such as MSFT. 
 
Thanks,
 
Greg

EMA is a function of todays Close and yesterdays EMA.
The mechanism is analytically described in AFL>AFL Scripting Host>Examples>a) Indicator example - Exponential moving average
After the math transormation, we may solve for C and get the Reverse EMA function.
I will call it CLOSEviaEMA to be more expressive.
In Indicator builder paste the
 
// Reverse EMA function, by D.Tsokakis, June 2003
P=20;
CLOSEviaEMA=0.5*((P+1)*EMA(C,P)-(P-1)*Ref(EMA(C,P),-1));
Plot(C,"CLOSE",1,1);
Plot(CLOSEviaEMA,"CLOSEviaEMA",7,8);
 
to see actual Close and CLOSEviaEMA matching.
The Reverse EMA function is useful to anticipate next bar Close, if we suppose next bar EMA.
It is placed at

for further reference.
