Good Day!

I try to get realtime prices (FDAXZ9 for example) using OECAPICOM (in Delphi).
When I connect to sim.openecry.com I can see only currency pairs (USD/CAD for example). But when I connect to api.openecry.com I cannot see no contract.

What's wrong in my operations.?.

Sorry for my English...

Please make sure you downloaded the contracts for FDAX base contract first.
see OECClient.RequestContracts method for details.

Thank you for fast reply!

Here is my code:

procedure TFTest.ComboBox1CloseUp(Sender: TObject);
Var
I:Integer;
ConractList:IContractList;
FDAX:IBaseContract;
SomeContract:IContract;
begin
FDAX:=fMain.client.BaseContracts.ItemByIndex(ComboBox1.ItemIndex);
SomeContract:=FDAX.GetNearestContract;
fMain.client.RequestContracts(FDAX);
ListBox1.Items.Clear;
ConractList:=FDAX.Contracts;
ListBox1.Items.Add(FDAX.Symbol);//Control point
for I := 0 to ConractList.Count - 1 do//Here ConractList.Count = 0
ListBox1.Items.Add(ConractList.ItemByIndex(I).Symbol);
if Assigned(SomeContract) //Not Assigned
Then ListBox1.Items.Add(SomeContract.Symbol);
end;

In comment I sign some values of variables.
In Control point I make me sure I right symbol pass throu the code.

So: It is realy FDAX basecontract, and no concret contracts it contain...

May be I mast to subscribe translation of this contracts somewhre else except my programm.?.

OEC API is asynchronous. You need to wait until contracts are downloaded and event OnContractsChanged is raised before you can see the contracts you have requested.
