The relation for today is
CLOSEviaEMA=0.5*((P+1)*EMA(C,P)-(P-1)*Ref(EMA(C,P),-1));
If tomorrow´s EMA is tEMA and tomorrow´s Close is tClose, then
tClose=0.5*((P+1)*tEMA-(P-1)*EMA(C,P));
Since P and EMA(C,P) are already known, if I suppose tEMA I will know
tClose from the last relation.
I hope it is clear.
