EFS limitations with multiple quotes

[mk1979]

Hello,

Just looking for some clarification on what can be done with EFS vs
the Desktop API.

I would like to access a large number of quotes in real time within
the same program/script, but it looks to me as though EFS is geared
towards analysis of a single quote at a time. Is this correct? For
realtime access to many quotes, do I need to be using the Desktop API
instead then?

Thanks

If by quotes you mean symbols then an efs can access up to a maximum of 7 external symbols.

Yes symbols. Thanks for the helpful reply.

Yeah, you have to do this externally. I have clients running 200 charts in esignal every day for signals/alerts. I also have built an external scanner (java-script based) that can run on hundreds of symbols every day.

If you get to the point that you want to run a script on large numbers of symbols or have a single script that needs data from large numbers of symbols, the only way to do it is "build your own" - like I've done.

But it can be done and if you need help let me know?

Brad -
what did you mean by "build your own" - is that by the way of the Desktop API or is there some other means to accomplish an external scanner as you have built?

Thanks,

Yes, I built my own with the Desktop API.

It does what I want right now and I'll add more to it over the next few months. Here are some of the basics..

Backtesting
Position management
Unlimited price data elements
Support for basic indicators (about 15)
Built in custom indicators (for client's needs)
Signal reporting
Connects to mySql Databases (data reporting)
Java Script Enabled (write your own scripts - like EFS)
Build/manage Portfolios
Connects to MENT Trader Service (for auto-trading)

So, in the long run, I have a pretty good head-start, but there is so much left to do with it.

For all you EFS coders, there are still many things you can do within EFS. In most cases, you don't need to develop outside of EFS (unless there are specific needs to do so).

My scanner project did not start of being for "esignal". It started as a specialty applicaiton for another client that never paid me. Then I took over and made it what I wanted (including "esignal's data").
