Creating a Custom Index with EFS

[tharnett]

I am new to EFS studies and am trying to find a way to chart a custom index that I have created. Currently I create the value in MS Excel but want to be able to write and EFS and plot it in eSignal. I read a post from Alexis Montenegro that said EFS only allows up to 5 symbols (I think) to be processed by an EFS Indicator. Is this true?

My custom index is composed of 10 stocks and I also use their shares outstanding to create a market cap for each one so I can weight it properly. Can anyone provide me with any help on this or answer whether it can be done using EFS?

Thanks!

The symbol limit in EFS is now at 7 (up from 5)
Having said that you may be able to plot the index directly as a symbol. For more information on creating composite symbols, spreads, etc see this article in the eSignal KnowledgeBase

Alexis,
Thanks for the very quick reply. I realize I could do what you suggested and may have to resort to doing it that way. However, do you think I could also just create a function for each symbol I have and then call all those functions in the EFS I am trying to create or does the symbol limit still prohibit this way also?

Example:
(stock price 1 * shares outstanding) = Function1
(stock price 2 * shares outstanding) = Function2
(stock price 3 * shares outstanding) = Function3
(stock price 4 * shares outstanding) = Function4
etc.
etc.

EFS = Function1 + Funtion2.......

Thanks!

I am not positive but I think you will hit the symbol limit even when using separate functions whether internal or external. You may want to have Jason or someone else from eSignal confirm this though.

Alex is correct.

So even if I use callFunction() within my EFS and fetch the symbols in the other (called) EFS I'm not going to get around the symbol limit?

Is that because a "called" EFS is treated as part of the EFS that calls it?

Is it possible to spawn another EFS with the symbol as a parameter? i.e. is there a way (a function) to invoke the right click Formulas -> myEFS.efs menu sequence? And then do the opposite of unloading the EFS?

That is correct. The called efs is loaded as part of the efs that is calling it.
As to your second question I don't believe there is a way to do that
