Gujrati Funda of Trading with Excel


I was just trying to understand how it works. I guess there is more to it than what the file has. I was trying to see, how this gives inputs for s trade entry for the next day. If it is meant for BTSt, i was totally off teh mark in understanding it

Thanks for your reply.
anybody needs an afl for this?
mymsf[ 0 ] = C[ 0 ];
for( i = 1; i < BarCount; i++ )

mymsf[ i ]=mymsf[ i-1 ]+(C-mymsf[i-1])*.33;
Plot(Close, "Price",colorBlack, styleCandle);
Buy=msfBuy ;
Sell=msfSell ;
PlotShapes( Buy* shapeUpArrow , colorGreen, 0);
PlotShapes( Sell* shapeDownArrow , colorRed, 0);

Filter=1 ;
NumColumns = 0;
AddColumn(Close,"CMP", 1.2);
AddColumn((Close-Ref(C,-1))*100/Ref(C,-1),"change", 1.2);
AddColumn(Ref(Close,-1),"PR.Close", 1.2);
AddColumn( IIf( Buy, 66, 83 ), "Signal" , formatChar,2,4 );
AddColumn(O,"open", 1.2);
AddColumn(H,"HIGH", 1.2);
AddColumn(L,"low", 1.2);
AddColumn(C,"close", 1.2);
