How to build own index indicator ?

[KarlBochez]

I totally new to the e-signal platform so please do not be too hard with me. I would like to build my own real-time market index indicator (market breath indicator) but looking at the EPS, it seems like I can only access one single security from inside the script. Hence my questions:
1) Is there a way to access multiple price series (multiple securities) from inside an EPS in real-time ?
2) Any other technological possibilities ? (FYI: I would like to output the value of my indicator on a e-signal chart, that's why I thought EPS may fit for what I'm trying to do)
Thank you very much in advance for your help.
Regards
Karl

Hi Karl,

I'm pretty sure you can include up to 7 symbols in an EFS (eSignal Formula Script) and build an indicator that way. If you needed more than 7 symbols, you'd need another solution.

To learn more about EFS, try searching these forums or referencing the EFS Knowledgebase.

Thanks and welcome to eSignal!

Edit: Symbol limit for EFS is actually 7, not 5 as was previously noted
