Trade number limits for pairs in a portfolio
« on: October 14, 2021, 06:25:32 pm »
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?

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

Am I correct?

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?

The PTL Trader app handles this gracefully. When requests are rejected because of pacing violation they are retried in > 10 minutes so at the end all symbols are covered. So this limitation at IB side does not impose any real limitation for the portfolio size.
