Help with efs code for index

[Trader Al]

Hi

Is it possible to make an efs code for the smart money flow index of the Dow index?

At

http://www.wallstreetcourier.com/technician/timing-indicators/smart-money-indicator.htm

this link they describe that it is quite simple to create. I would like to make a have a efs code that would plot the Dow with the smart money flow index either overlayed or underneath the Dow. Is this easy enough to do or not?


I presume that the smfi would also be able to be plotted for regular stocks to would be great.

Thanks.

Al
