To request for any Generic Tick Type, you just need to specify the name of the generic tick type as the Topic string in the RTD formula. By default, all Generic Tick Types are automatically requested. User just need to directly specify the Topic as the name of a generic tick type to populate the data to Excel. In order to consume less data resource and make your market data request more efficient, you can directly specify the Generic Tick Type to be requested by defining string *"genticks=id1,id2,…"*. For example, to request 52-Week High price, only Generic Tick Type = 165 is required. The below formula will only request Generic Tick Type = 165: `=RTD("Tws.TwsRtdServerCtrl",,"SPY@SMART", "Week52Hi", "genticks=165")` | Generic Tick Type Name | Topic String | Description | Generic Tick Required | | ----------------------------- | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------------------- | | Auction Volume | "AuctionVolume" | The number of shares that would trade if no new orders were received and the auction were held now. | 225 | | Auction Imbalance | "AuctionImbalance" | The number of unmatched shares for the next auction; returns how many more shares are on one side of the auction than the other. | 225 | | Auction Price | "AuctionPrice" | The price at which the auction would occur if no new orders were received and the auction were held now.
