These options don't seem to trade very much. I don't know why. Even CME's website has minimal data (and low if not zero volume) https://www.cmegroup.com/markets/equities/dow-jones/e-mini-dow.quotes.options.html#optionProductId=319&expiration=319-M3 Jason Smith

| API Support » GF COM API Range/Volume Bar Subscription vs History Request May 23, 2023 @ 02:52 PM (Total replies: 2) | |||||
|
Because of the way that volume / range bars are created, that's really not possible. They are generated based on the timestamps that are passed in (or current time if none is given) The better way of doing this is to do the subscription first, then doing the historical request using the timestamps of the first bar you get back from the subscription (this is how trader does it) Jason Smith

Sorry, I forgot to tell you this. Since you're just interested in the theoretical margin for the entire order, place the legs as hypo positions instead of hypo orders. Hypo Positions are calculated all together, while hypo orders tries to find the worst-case situation of which orders would fill or not. Jason Smith

I've tested sending mutliple orders in a margin request with the latest COM api (4.11.210.227), and it works fine for me. HypoOrders and HypoPositions are immutable by design (same for the .NET api) Jason Smith

From what i remember about the margin calc, the best way would be to place each leg as an separate order in the calc request. This can be done as the following: GF_Api_COM::IMarginCalculationRequestBuilderPtr builder; builder.CreateInstance(__uuidof(GF_Api_COM::MarginCalculationRequestBuilder)); GF_Api_COM::IAccountListPtr accs = GFAPI()->Accounts->Get(); GF_Api_COM::IAccountPtr account = accs->GetAt(0); builder = builder->WithAccountID(account->id); //Loop next line for each contract / side / quantity builder = builder->WithOrder(GFAPI()->Margin->CreateHypoOrder(contract->id, GF_Api_COM::OrderSide_Buy, quantity)); Jason Smith

its a flag enum. try: VARIANT_BOOL hasDom = (pDfe->SubscriptionType | GF_Api_COM::DataFeedEntitlementSubscriptionType::DataFeedEntitlementSubscriptionType_DOM) == GF_Api_COM::DataFeedEntitlementSubscriptionType::DataFeedEntitlementSubscriptionType_DOM)); The values in the enum are: TopOfBook = 1, DOM = 2 it is possible to have BOTH be true, in which case the underlying value of the enum will be 3.
