How shall Field 30 (Quantity) in Commission Delegated Regulation (EU) 2017/590 Annex I Table 2 be reported for a transaction where there have previously been acquisitions or disposals that are excluded from the meaning of a transaction? For example, a decrease in notional amount in a financial instrument which has previously had pre-determined contractual down payments exempted from transaction reporting under Commission Delegated Regulation (EU) 2017/590 Article 2(5)(j)?

Under which circumstances a trading venue may cancel, vary or correct a transaction?

Article 1(2)(d) of RTS 8 establishes that quotes shall be deemed to have competitive prices where they are posted at or within the maximum bid-ask range set by the trading venue. Does this mean that trading venues have to have published maximum bid-ask ranges for all instruments traded on their venues or only for the instruments on which they have a market making scheme in place?

In terms of the Order to Trade Ratio (OTR), how should a trading venue tackle cases where a market participant has executed no trades after the submission of a high number of orders?

Could trading venues set out different OTRs for different types of market participants (e.g. firms engaged in a market making scheme)?
