Re: [amibroker] TD Pressure Ratio Indicator

[Thomas Ludwig <Thomas.Ludwig@xxxxxx>]

Dave,

perhaps something like this:

Days=Param("Days",10,1,50,1);

up=C>O;
down=C<O;
BP=Sum(up*V,Days);
SP=Sum(down*V,Days);

PI=100*BP/(BP+SP);
Plot(PI,"Pressure Indicator", colorRed,styleLine);

Greetings,

Thomas
