Hi,

We try to request interval data using HIT command, but we get strange error back, that the symbol is not valid. Why? What's wrong? Some of symbols are Ok, some of them (with another strikes) are invalid... Very strange behavior.

For example:
TX: HIT,BAC1422B29,60,20130711 071126,20140127 061126,,1,,1
RX: E,Invalid symbol.

Full list of symbols which we can not get:
BAC1422B34
BAC1422N25
BAC1422N24
BAC1422B33
BAC1422B32
BAC1422N27
BAC1422N26
BAC1422B31
BAC1422N29
BAC1422N28

BAC1422B30
BAC1422N32
BAC1422N33
BAC1422N34
BAC1422B3
BAC1422N36
BAC1422N35
BAC1422N1
BAC1422N2
BAC1422B4
BAC1422B25
BAC1422B24

BAC1422B23
BAC1422B22
BAC1422B29
BAC1422B28
BAC1422N22
BAC1422N23

The example you gave appears to be a strike that has not received any activity as of yet and so that would not exist yet, so the next question I would have is, where did you get your symbol list? I am not able to find where our system has this symbol anywhere.

SBF,s,BAC1422B2
BAC1422B2,14,2,BAC FEB 2014 C 2.000,
BAC1422B20,14,2,BAC FEB 2014 C 20.000,
BAC1422B21,14,2,BAC FEB 2014 C 21.000,

Okay, I got your idea. But these 4 symbols from the list - BAC1422B3, BAC1422B4, BAC1422N1, BAC1422N2 - exist and can be found on your site using Symbol Lookup, but still return the same error.

These symbols have bid and ask data, but no trade data. Hence, why they are available via level one, but not in history. They will be part of history once they have traded.
