Trade number limits for pairs in a portfolio

(1/2) > >>

Hello,

I'm testing PTL Trader on a paper account, and it seems okay so far.

I'm wondering how many pairs can be traded at the same time in a bound portfolio.
Are there any limitations assigned by IB for the number of data feed?

tcima:
I checked with IB site, and the limit may be 100 for standard data subscription.
That means 50 pairs at maximum.

Am I correct?

admin:
Yes, correct. I think the limit is slightly lower, PTL Trader subscribes to 2 or 3 symbols internally to detect market holidays...

Thank you for your comment, Karma.

I learned a lot of things about PTL Trader in the last few days.
I look forward to finding how the app works in real trade.

Hi,

I happened to see the following IB's page on Historical Data Limitations:
https://interactivebrokers.github.io/tws-api/historical_limitations.html

They say that "Making more than 60 requests within any ten minute period" for historical data triggers Pacing Violation.
When I start up PTL Trader, it seems the app is sending historical data requests to TWS API.
In this case, is the number of pairs in a portfolio limited to 30 (60 legs in total) because of IB's Pacing Violation?
