Perhaps you are looking for a complex symbol lookup expression using 'or'? There is an example here that may be useful: https://gainfutures.com/GFAPI/html/0522b8f0-2870-43a9-ad0a-76a4421cbac1.htm Maybe something similar to this: _requestID = client.Contracts.Lookup.ByCriteria(

Market Data » multiple subscription Jun 13, 2022 @ 07:47 AM (Total replies: 6) | |||||
Hello, The code you have posted does fetch contracts matching the criteria into the local cache. However, usually when we say 'subscribe' we refer to a price, charts, or DOM subscription on one of those contracts. This will give you periodic updates for this data. Subscription is a separate call from symbol lookup. You can see code examples here: https://gainfutures.com/GFAPI https://gainfutures.com/GFAPI/html/4e2865e8-7ac9-457e-8d5a-6d930f3408a8.htm |

Order Execution » Getting real time position value Jan 06, 2021 @ 12:12 PM (Total replies: 1) | |||||
One change in GFAPI is that you need to subscribe to the contracts in the position in order to get an accurate position. Perhaps this is the issue? Here is a sample for doing so: https://gainfutures.com/GFAPI/html/de577afb-edad-4021-a3cc-1fd943896903.htm |

API Support » PriceTick vs SubscriptionTick Jan 06, 2021 @ 11:05 AM (Total replies: 1) | |||||
Hello. Are you asking about the difference between price subscriptions and tick subscriptions?https://gainfutures.com/GFAPI/html/T_GF_Api_Subscriptions_Price_IPriceSubscriptionApi.htm https://gainfutures.com/GFAPI/html/T_GF_Api_Subscriptions_Ticks_ITicksSubscriptionApi.htm A tick is something that you would put on a graph, representing the smallest time unit, while a price subscription will give you full price data. Probably you want to call gfClient.Subscriptions.Price.Subscribe(contractID), and listen to the PriceTick or PriceChanged events. It may not give you price data every second, but prices don't update every second anyway. When the price changes, an event will be raised. |

Hello, 1) No, there is currently no silent install option. 2) There is also no way to specify a different directory. 3) The version is in the dll File Version metadata, so you could programmatically inspect that. We will keep these in mind for future development. |

The DateTime is UTC, it's just that the DateTime.Kind is set to DateTimeKind.Unspecified when the message from the server is deserialized. But you are right, it would be more correct as DateTimeKind.Utc, and we plan to address this in a future release. |

The time is already in UTC, so I suspect you just need to remove the ToUniversalTime call. |
