Yo, steve
How are you,
do you remenber the di code in Ms language,
Steve
are you fine?
do you remenber this Di code in ms language, this one is very close
but there is a problem of scale I have never resolved
steph
A:=(H+L+2*C);
B:=Mov((HHV(H,2)-LLV(L,2)),19,E);
Buy:= {BuyPressure}
V/Mov(V,19,E) * ((A>=Ref(A,-1)) +
(A<Ref(A,-1)) /
Exp((0.375 * (A+Ref(A,-1)) /b ) *
(Ref(A,-1)-A) / A));
Sell:={SellPressure}
V/Mov(V,19,E) * ((A<=Ref(A,-1)) +
(A>Ref(A,-1)) /
Exp((0.375 * (A+Ref(A,-1)) / B ) *
(A-Ref(A,-1)) / Ref(A,-1)));
A:=Mov(Buy,19,E)-Mov(Sell,19,E);
B:=Mov(Sell,19,E)+Mov(Buy,19,E);
(A/B)*100
