Hi, this is my request with 55=ES (like the example string in the GainFutures documetation https://gainfutures.com/GFAPI/?topic=html/bfd39591-ba7a-460f-932b-3f16d2533772.htm):

8=FIX.4.4
9=130
35=D
1=API010034
11=756d02a5-56a3-4e19-96f8-0136eef68281
21=1
38=1
40=1
54=1
55=ES
60=20201006-11:29:41.420
200=202010
461=FXXXXS
10=015


...And this is the rejection for 58=Unknown contract:


8=FIX.4.4
9=267
35=8
34=2
49=OEC_TEST
52=20201006-09:30:04
56=MConcas
1=API010034
6=0
11=756d02a5-56a3-4e19-96f8-0136eef68281
14=0
17=OECFIX:637374441025750563:210
37=NONE
38=0
39=8
40=1
54=1
55=ES
58=Unknown contract
60=20201006-09:30:04.517
103=1
150=8
151=0
200=202010
461=FXXXXS
10=247


Can anyone see what's wrong? Thanks for help.

The server is stating invalid month was provided. ES does not have October contract. Please review Contract Specs on the exchange site: https://www.cmegroup.com/trading/equity-index/us-index/e-mini-sandp500_contract_specifications.html
