Member States shall allow a regulated market to adjust its fees for cancelled orders according to the length of time for which the order was maintained and to calibrate the fees to each financial instrument to which they apply.

It is therefore appropriate to allow for trading venues to adjust their fees for cancelled orders according to the length of time for which the order was maintained and to calibrate the fees to each financial instrument to which they apply.

the extent to which orders to trade given or transactions undertaken or orders cancelled include position reversals in a short period and represent a significant proportion of the daily volume of transactions in the relevant financial instrument, a related spot commodity contract, or an auctioned product based on emission allowances, and might be associated with significant changes in the price of a financial instrument, a related spot commodity contract, or an auctioned product based on emission allowances.

Arrangements where the client of a member or participant of a trading venue, including the client of a direct clients of organised trading facilities (OTFs), submit their orders through arrangements for optimisation of order execution processes that determine parameters of the order other than the venue or venues where the order should be submitted through SORs embedded into the provider's infrastructure and not on the client's infrastructure should be excluded from the scope of direct electronic access since the client of the provider does not have control over the time of submission of the order and its lifetime.

However, where a person comes into possession of inside information, there should be a presumption that any subsequent change relating that information to orders placed before possession of such information, including the cancellation or amendment of an order, or an attempt to cancel or amend an order, constitutes insider dealing.
