GTX supplies separate sessions for the different liquidity types. Liquidity types distinguishes liquidity in it's market data feed according to the following scopes: - "Interest" only orders matchable immediately
- "Firm" LP feeds matchable immediately
- "LastLook" LP feeds that require validity check.
For PriceDepth books, GTX can aggregate scope. The consequence of this is rungs will be a mixture of Interest, Firm and LastLook. If you choose not to aggregate scope, Duplicate price level entries will be seen in the PriceDepth book. Fortunately, GTX can supply separate sessions for the different liquidity types, thus providing clean PriceDepth books. Please refer to PassthruFields above and contact MarketFactory Contact for more details. GTX OrderDepth books do not populate MDEntryTime. The priority of orders within the same price level is only known by GTX. |

...
PriceDepth subscriptions, this venue associates the MDEntryID with a given price level - not the price itself. As such, an individual ID will have a much longer lifetime than the subscriber may otherwise expect. For example, an ID associated with the Top of Book Bid will only be deleted in the unlikely scenario that Bid liquidity should be completely removed for that instrument. |
Orders
Pegged Orders
MidPricePeg, MarketPeg and PrimaryPeg are supported for PegPriceType.
If the Limit Price is populated, then the Limit Price will be pegged, otherwise the specified StopPx will be pegged.

Marketable
| Note |
|---|
|
Clients can consume Marketable indicator as a BodyPassthruField in the ExecutionReport if their Orders session is configured for this field by GTX. Please note that this field is not available by default. Marketable indicates the order was matched with an LP quote / order by the GTX matching engine. If the order is not marketable (for reasons such as, the market moved and there is no quote/ order that matches the Limit price) then this tag would provide that information to the client.
This tag is useful for clients to understand if they got Rejected by the LP or if their order was not presented to the LP in the first place due to ‘no match’. - '
Y': the order was matched by GTX engine (i.e. the order was marketable and was presented to the LP). - '
N': the order was not matched (i.e. the order was not marketable and never presented to an LP).
Please contact MarketFactory Delivery team if you need Marketable field enabled in your Orders session. |
Iceberg and Dark Orders
- It is possible to make Iceberg Orders using
HasExtendedFields[1].MaxShow. - To make Dark orders, simply make MaxShow = 0.
- MaxShow is ignored for IOC orders.
Supported TimeInForces
...
ExposureDuration will override ExpireTime.
Order Modification
If DiscretionOffsetValue(389) is omitted, the value from the original order will be removed i.e. this tag needs to be explicitly specified every time an order is replaced.
TransactTime: Unlike Unlike NewOrderMultilegs, GTX will NOT reject MiltilegOrderCancelReplaceRequest messages that appear to have been delayed, i.e. TransactTime is ignored for MiltilegOrderCancelReplaceRequest.
The following Values may be changed:
OrdTypeTimeInForce- EffectiveTime
- ExpireTime
ExposureDurationMinQtyMaxShow- DiscretionOffsetValue
LegPriceLegOrderQty: should be the total intended order quantity, including amount already executed for this chain of orders.
