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):


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

8=FIX.4.49=26735=834=249=OEC_TEST52=20201006-09:30:0456=MConcas1=API0100346=011=756d02a5-56a3-4e19-96f8-0136eef6828114=017=OECFIX:637374441025750563:21037=NONE38=039=840=154=155=ES58=Unknown contract60=20201006-09:30:04.517103=1150=8151=0200=202010461=FXXXXS10=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
