UDS on the Exchanges

Currently, CQG supports UDS on CME, Eurex, Euronext, ICE, Montreal, and Turquoise.

CME

CME rejects strategies citing a reverse buy/sell indicator.

For example, instead of buying a short straddle you should sell a long straddle, as these two strategies are equivalent: Buy UDS(-P.CLEK55050-C.CLEK55050) = Sell UDS UDS(P.CLEK55050+C.CLEK55050) =>(-P.CLEK55050-C.CLEK55050)= -(P.CLEK55050+C.CLEK55050).

Use these strategies instead:

Bear Call Spread	Bear Put Spread

Iron Butterfly Long	Iron Butterfly Short

If your order is rejected by an exchange, make sure the strategy is correctly defined according to exchange rules.
