I didn't choose the thread heading and I've not made any contribution
anywhere to a stochastic lookahead formula. It seems to me that something
using H, L and C is going to be rather difficult to construct look-ahead
code for. I may be wrong but I think that there could be many possible price
variations for any projected stochastic value, not just the one as with the
RSI look-ahead.

Roy, thanks for the response. Thanks to "CUCU" from Turkey for the initial
input. I see nothing pertaining to the Stoch. Is there a substitution or
another set of formulae? Marshall

'cucu' from Turkey supplied this on the StockCentral forum as an RSI
lookahead formula. All the credit is his.
valuemid:=Input("RSI Value Mid",1,100,50);
wildpermid:=Input("Wilder Time Periods
Mid",1,100,8);
exppermid:=2*wildpermid-1;
{Average Up Close-Mid};
aucmid:=Mov(If(C>Ref(C,-1),C-Ref(C,-1),0),exppermid,E);
{Average Down Close-Mid};
adcmid:=Mov(If(Ref(C,-1)>C,Ref(C,-1)-C,0),exppermid,E);
xmid:=(wildpermid-1)*(adcmid*valuemid/(100-valuemid)-aucmid);
revengrsimid:=If(xmid>=0,C+xmid,C+xmid*(100-valuemid)/valuemid)
revengrsimid;
I tweaked it a bit to conform to my own style but my version is functionally
identical the the one above.
{RSI Price Lookahead}
R:=Input("RSI Threshold",1,100,50);
D:=Input("RSI Periods ",1,100,10);
K:=Ref(C,-1);
Up:=Wilders(If(C>K,C-K,0),D);
Dn:=Wilders(If(K>C,K-C,0),D);
X:=(D-1)*(Dn*R/(100-R)-Up);
If(X>=0,C+X,C+X*(100-R)/R);
The object of this as an indicator is that an RSI periods and threshold
value can be set, and then the last bar of the indicator will plot the next
CLOSE that is necessary for the RSI to plot the threshold value. Changing
the last line to
LastValue(revengrsimid); or
LastValue(If(X>=0,C+X,C+X*(100-R)/R));
in the relevant indicator will plot a straight line at the required CLOSE.
