EFS Error: Symbol Limit(7) for a formula has been exceeded

[bizken]

Hi Folks,

Could someone help me to resolve this problem?

Problem: Sum volume of "XJO-ASX" component shares

Error Message : Symbol Limit(7) for a formula has been exceeded


Code:

Request: Error message indicates that there is a limit on symbols for formula. Is it possible to increase that limit? or are there any alternative methods to get the aggregate volume of xjo-asx components?

Thanks

A single EFS can access up to a maximum of 7 external symbols and/or intervals.
As far as I know it is not possible for a user to increase that limit

Thanks for the reply. 7 symbols for a formula could be an software architectural limit, but there must be way to increase the limit, don't you think so?

I am trying to get volume related indicators for index ASX200 (XJO-ASX) to improve my trading...

Would any of you benefit if esignal provided Aggregate volume of "XJO-ASO" components as a symbol?

Did anyone try symbols $TRIN,$TICK,$TRINQ and $TICKI?

As I said in my previous reply it is not possible for a user to increase the limit.
Based on past statements by eSignal representatives it seems unlikely that eSignal will increase it. You may want to run a search through this forum as the topic has been discussed before

Thanks Alex, I do understand reasons of symbol limit for a formula

However, I do not want to increase limit myself :;, I just wanna get aggregate volume of ASX200 index components.

You may want to post your question in the Data Inquiries forum rather than the EFS Studies forum since this is a data related question and no longer a specific efs programming issue or question
