To provide improved performance, TOCOM Gateways support multiple Order Sessions. To enable multiple Order Sessions, you must contact the Exchange for additional Login User IDs and properly configure the hostinfo.cfg file.
Multiple order sessions greatly improve TT Gateway performance and alter how the TOCOM Gateway processes orders and fills.
TOCOM Gateways can be configured with as many as 50 [TTO_#] sessions. Per TOCOM restrictions, only 50 users may be logged in per Network Gateway.
When using two Order Sessions, the TOCOM Gateway routes all orders through the [TTO_1] session while the [TTF] session processes fills and some order data (i.e., market state changes, stop triggers, etc.) You must uncomment and configure the [TTO_1] section to enable the second Order Session.
If you add additional Order Sessions, the TOCOM Gateway automatically load balances order routing between each [TTO_#] session while the [TTF] session continues to receive fills and order data.
To configure multiple sessions on a gateway that supports a multiple members, refer to hostinfo.cfg: Multi-Member.
