I am using Delphi and hence the COM interface to connect.
After successfully logging in, I can load things like base contracts and accounts but the list of specific contracts appears to be empty.
Below is the delphi code test procedure I am using and below that is the output log resulting from it.

Thanks for any help.

procedure TOECServerForm.connectToOEC(Sender: TObject);
begin
log('Trying to connect to OEC...');
OECClient1.UUID := '9e61a8bc-0a31-4542-ad85-33ebab0e4e86';
OECClient1.Connect1('api.gainfutures.com', 9200, ***, ***, true);
end;

procedure TOECServerForm.loginComplete(Sender: TObject);
begin
log('login complete');
log('contracts: ' + intToStr(OECClient1.Contracts.Count));
end;

procedure TOECServerForm.testData(Sender: TObject);
var
i: integer;
obc: BaseContract;
ibc: IContract;
icontList: IContractList;
begin
log(intToStr(OECClient1.BaseContracts.Count) + ' base contracts found');
log(intToStr(OECClient1.Contracts.Count) + ' contracts found');

obc := OECClient1.BaseContracts.FindBySymbol('ES');
OECClient1.RequestContracts(obc);

log(intToStr(OECClient1.Accounts.Count) + ' accounts found');
log('Account: ' + OECClient1.Accounts.First.Name);

log(obc.ToString);
log(obc.Name);
log(obc.Currency.Name);
log(obc.ContractGroup.Name);

ibc := OECClient1.Contracts.GetContract(1, true);
if ibc <> nil then
log(ibc.Name);

icontList := OECClient1.Contracts;
log(intToStr(icontList.Count) + ' contracts found');
end;

Hi Thomas,

Please see our FAQ in our API documentation.

http://www.gainfutures.com/api/api/?topic=html/c1dcf698-2b86-4259-81c1-cb749c226e70.htm


In your case, you will want to implement the above event and avoid checking the contracts immediately after your request. The API will not have had time to send the request and receive a response. Let me know if this works for you.
