Hello,
 
There is no "method" but API simply sends the error message to any client if symbol limit is reached.
 
(error code 101 Max number of tickers has been reached.)
 

Best regards,

made a short test with the Amibroker IB plugin before IB turns their
servers off over the weekend:

If I'm not mistaken, the limit of 100 symbols applies to the sum of
the number of symbols watched in the TWS and the number of symbols
watched via API.  (?)


Which means that the answer to (1) would be "no".

Interestingly, TJ's API plugin opens a pop up message to warn the
customer when the total number of symbols (TWS + API) exceeds the
limit.

This implies that is somehow possible via TWS API to detect when the
symbol limit is reached. (???)  Interesting!   Glanced briefly over
the TWS API docs, but didn't find any such method.   But I could have
overlooked it, have not read the TWS docs in detail yet.  (and
they're not written well, for example no Javadoc used!!!).
