Eurex, the Swiss-German derivatives exchange, is unlikely to take action against a trader using anti-competitive techniques to deal German government bonds futures, even though his peers have accused him of manipulating the market.

The unidentified Swiss trader uses a technique, known as "flipping", to make profits in the Schatz contracts while making it difficult for other small traders, or locals, to execute orders. Flipping involves entering large buy orders on the system, then waiting for other traders to react before cancelling the order, re-entering it as a sell and profiting from other traders' reactions.
