Is this a broker generated error message?

Hi

One of my clients tried to put a trade on the SPI this morning through Pat Systems and got this error message:

"PATS host rejected. Limit breach ( TA Max Size). Affected Prder: Sell 1 Market"

Just trying to get a handle on what this means if anyone can help?

Cheers

Hi Pete yes I would recommend to contact the broker and verify all is set up correctly on their end to trade the SPI.
