stargrazer -DTN Guru- Posts: 302 Joined: Jun 13, 2005 Right Here & Now	Posted: Sep 3, 2013 12:13 PM Msg. 1 of 3 Two questions regarding options in the Market Symbols file: 1) In the following line: AGII11418A36.36 AGII JAN 2014 C 36.360 OPRA OPRA IEOPTION The option base symbol is AGII1. But in the descripion, the underlying shows as AGII. What is the 1 after the symbol, but before the four digit date, represent? There are a number of symbols referencing the underlying this way. 2) The question is in the third set of symbols: These I know are regular options: SPY1304J145 SPY OCT 2013 C 145.000 OPRA OPRA IEOPTION SPY1319J145 SPY OCT 2013 C 145.000 OPRA OPRA IEOPTION These I know are mini options: SPY71319J145 SPY OCT 2013 C 145.000 OPRA OPRA IEOPTION But what are these options? With symbol SPYJ? The underlying in the description indicates SPY. SPYJ1304J145 SPY OCT 2013 C 145.000 OPRA OPRA IEOPTION SPYJ1319J145 SPY OCT 2013 C 145.000 OPRA OPRA IEOPTION

The numbers themselves are irrelevant (with the exception of minis = 7 as you have pointed out) except to indicate the option is adjusted "in some way". I do not know what the J represents. I have forwarded that over to our market data group for investigation. I'll let you know what I come up with on this one.
