The Cross Instrument Trading feature, allows you to route your orders to a micro/mini-contract while watching the parent instrument data on the Depth and Sales.
Please note that the Cross Instrument feature is available for direct connections only as we don't store symbols for bridged connections (i.e. NT8 and MT5).
When you open a Depth & Sales Instrument Search Window and load a contract that has its corresponding micro-contract, you will have the option to trade with the micro-contract while watching the parent instrument data by checking the Cross Inst box. Check the "Cross Inst" box and click OK.
Here's a video where you can learn more about the Cross Instrument trading feature:
In the example above, this will open a new Depth & Sales which will populate with ES data and the orders will be routed to MES. You will see this information (order routing and data) on the left top corner of your D&S.
Here is a list of the instruments available to Cross Trade. Please note that some instruments that have a micro may not be available to Cross Trade (i.e. FESX and NG), because some micro contracts do not follow the parent instrument price due to lack of liquidity, wider spread, and/or different price fluctuation.
CME
ES → MES
NQ → MNQ
RTY → M2K
6A → M6A
6B → M6B
6E → M6E
BTC → MBT
ETH → MET
Note: The minimum price fluctuation for M6A and M6E is 0.0001 and the minimum price fluctuation for 6A and 6E is 0.0005, so orders placed on the 6A and 6E DOM and routed to M6A and M6E that are not on the same price, will be rounded-up to the available closest price of the micro contract.
CBOT
YM → MYM
ZS → XK
ZC → XC
ZW → XW
Note: The minimum price fluctuation for ZC, ZW and ZS is 0.0025 and their minis are 0.00125. In those instruments you will only be able to place orders at each 0.0025 (parent), not at 0.00125 (minis).
COMEX
GC → MGC
SI → SIL
HG → MHG
NYMEX
CL → MCL
EUREX
FDAX → FDXS
