Hello,
Formula courtesy Dimitris Tsokakis:

Ucoeff= 1+UR/100;Lcoeff=1+LR/100;
Filter = 1;//for the autoanalyser
//Filter=tClose<Lcoeff*C OR tClose>Ucoeff*C;//for the graph

ema is calculated by using the following formula
PDA = Prior Day's Average (Begin with simple MA, thereafter PDA is
an exponential value.)
Exp = Exponent
CDV = Current Day's Value (If you are averaging a stock price, CDV is
today's price.)
EMA = Current Day's Exponential Moving Average
The formula to calculate the exponential average with this method is:
(CDV * Exp) + (PDA * (1 - Exp)) = EMA
I want to be able to estimate the close needed for and ema cross...
Any idea on how to accomplish it?
Thanks
