- ES and NQ: the E-mini S&P 500 and E-mini Nasdaq-100.
- MES and MNQ: their micro contracts.
- CL: crude oil.
- GC: gold.
Nothing else can be traded; the platform blocks any other symbol. ES, NQ, CL and GC each count as one mini. MES and MNQ each count as one tenth of a mini. Your account size sets how many minis you may hold.
Different markets are not offset against each other: long the S&P and short the Nasdaq is two positions of risk, not zero.
