Hi,

I just developed a simple client. I find I am receiving a few message types that I cannot find documention.

When I send f@ESM5 to the server, I receive the following:

1. P,@ESM5,10,1177.50,-6.50,-0.00548986,1094072,10,1193.50,1172.50,0.00,0.00,0,0,183,,21.,16:14t,850492,1183.75,1184.00,0.,,1177.75,,0,,,,,04/01/2005,,1177.50,06/17/2005,,,-6.50,0,,,,,-6.25,1,0.017834395,,12,2,76,,,1183.75,0.00,0.00,0.00,273453,,,,

2. F,@ESM5,10,,,1234.25,1164.50,,,,,,,,,,,,,,,,,,E-MINI S&P 500 JUN 2005,,,,,,,,,,,,,,0,12,2,,,8,43,03/07/2005,01/24/2005,,,

3. P,@ESM5,10,1177.50,-6.50,-0.00548986,1094072,10,1193.50,1172.50,0.00,0.00,0,0,183,,21.,16:14t,850492,1183.75,1184.00,0.,,1177.75,,0,,,,,04/01/2005,,1177.50,06/17/2005,,,-6.50,0,,,,,-6.25,1,0.017834395,,12,2,76,,,1183.75,0.00,0.00,0.00,273453,,,,


Now the questions are:

1. What is F message? Where can I find documentation?
2. What is P message? Where can I find documentation
3. Why I am receiving two P messages?

Thanks,
g

From the FAQ area on the API documentation:
Q: What are the F,P,Q and T messages?

ANS: These messages represent different types of data. F is the fundamental message, P is the summary message, Q is the update message, T is the Time message. Please refer the documentation for more details.

I can find F, Q, and T in the docoumentation but I cannot find P. Can you give me some help?

The P and Q messages have identical layout.
