Order Book Matching

Complex orders are matched on the complex book in a similar manner to orders on the simple book. For example, a multi-legged complex buy order will only be represented as a single buy order on the complex book. However, there may be differences in order priority between the simple book and the complex book. Please see the Exchange Rules for further details.
