Fields
| Name | Type | Size (bytes) | Description |
|---|---|---|---|
| Id | Integer (signed) | 8 | The unique identifier of this InstrumentGroup. |
| Status | Set of Status | 4 | |
| ShortName | String | 24 | The short text identifier of this InstrumentGroup. |
| Name | String | 48 | The long text identifier of this InstrumentGroup. |
| FeeBasis | One of FeeBasis | 1 | |
| FeeBuy | Integer (signed) | 8 | |
| FeeSell | Integer (signed) | 8 | |
| MinFeePerOrderBuy | Integer (signed) | 8 | |
| MinFeePerOrderSell | Integer (signed) | 8 | |
| Session | Foreign key to Session | 8 | The Sessions that define the matching algorithms that may be used for Products are maintained in this table. |
| OrderType | Set of OrderType | 4 | |
| LotSize | Integer (unsigned) | 4 | An InstrumentMarket may trade in lots, where a lot is a fixed number of units of the InstrumentMarket. LotSize defines the number of units per lot for an InstrumentMarket. If an InstrumentMarket trades in single units, the LotSize is 1. Prices are always on a per-lot basis. This value determines the LotSize for the instances of this InstrumentGroup. |
| HiddenMaxRatio | Integer (signed) | 8 | For hidden quantity orders, the maximum ratio of the total quantity of an order to the hidden quantity. For example, if HiddenMaxRatio is 10 then an order with a total quantity of 10,000 lots may not have a hidden quantity less than 1,000 lots. |
| PriceStepSet | Foreign key to PriceStepSet | 8 | Defines the valid price steps for the InstrumentGroup. This Trading Rule is a reference to a PriceStepSet instance that defines the steps that apply at each price level for the InstrumentGroup. |
| QuantityStepSet | Foreign key to QuantityStepSet | 8 | Defines the valid quantity steps for the InstrumentGroup. This Trading Rule is a reference to a QuantityStepSet instance that defines the steps that apply at each price level for the InstrumentGroup. |
| PriceDecimals | Integer (unsigned) | 1 | The number of decimal places that should be used when interpreting prices for this InstrumentGroup. Prices within MarketGrid are stored and communicated as integers with fixed numbers of decimals. This field specifies how many digits are to the right of the decimal point. For example, a price of 10350 with PriceDecimals set to 2 means 103.50. |
| QuantityDecimals | Integer (unsigned) | 1 | The number of decimal places that should be used when interpreting quantities for this InstrumentGroup. Quantities within MarketGrid are stored and communicated as integers with fixed numbers of decimals. This field specifies how many digits are to the right of the decimal point. For example, a quantity of 12345 with QuantityDecimals set to 3 means 12.345. |
| ValueDecimals | Integer (unsigned) | 1 | The number of decimal places that should be used when interpreting the value of this InstrumentGroup. Values within MarketGrid are stored and communicated as integers with fixed numbers of decimals. This field specifies how many digits are to the right of the decimal point. For example, a value of 1150000 with ValueDecimals of 2 means 11,500.00. |
| MinQuantity | Integer (signed) | 8 | The minimum quantity permitted for this InstrumentGroup. |
| MaxQuantity | Integer (signed) | 8 | The maximum quantity permitted for this InstrumentGroup. |
| MinValue | Integer (signed) | 8 | |
| MaxValue | Integer (signed) | 8 | |
| Scale | Integer (signed) | 8 | A scaling factor for distribution of the traded Value today for this InstrumentGroup through the API. Value will be scaled (divided by) this field, if it is non-zero. |
| MinPrice | Integer (signed) | 8 | |
| MaxPrice | Integer (signed) | 8 | |
| PriceZeroAllowed | Integer (unsigned) | 1 | |
| PriceNegativeAllowed | Integer (unsigned) | 1 | |
| FeeType | One of FeeType | 1 | |
| FeeMaker | Integer (signed) | 8 | |
| FeeTaker | Integer (signed) | 8 | |
| MinFeePerOrderMaker | Integer (signed) | 8 | |
| MinFeePerOrderTaker | Integer (signed) | 8 | |
| MaxFeePerTradeBuy | Integer (signed) | 8 | |
| MaxFeePerTradeSell | Integer (signed) | 8 | |

| MatchingPriorityType | One of MatchingPriorityType | 1 | If set to 1, indicates that for this InstrumentMarket, Market Maker orders will be placed at head of each order book (by price). |
| OrderPriceLimitUpLTP | Integer (signed) | 8 | |
| OrderPriceLimitUpRef | Integer (signed) | 8 | |
| OrderPriceLimitDownLTP | Integer (signed) | 8 | |
| OrderPriceLimitDownRef | Integer (signed) | 8 | |
| CircuitBreakerUpLTP | Integer (signed) | 8 | |
| CircuitBreakerUpRef | Integer (signed) | 8 | |
| CircuitBreakerDownLTP | Integer (signed) | 8 | |
| CircuitBreakerDownRef | Integer (signed) | 8 | |
| UpdateNumber | Integer (unsigned) | 8 | A number that records every change that happens to a record. It is primarily used to avoid write after read problems when an intermediate write has changed the originally read record. |
| OwnerUser | Foreign key to User | 8 | The Id of the User that owns this InstrumentGroup. |
| OwnerGroup | Foreign key to Group | 8 | The Id of the Group that owns this InstrumentGroup. |
| OwnerFirm | Foreign key to Firm | 8 | The Id of the Firm that owns this InstrumentGroup. |
| CreateUser | Foreign key to User | 8 | The Id of the User that created this InstrumentGroup. |
| CreateTimestamp | Integer (unsigned) | 8 | The time at which this InstrumentGroup was created. |
