There is also the mid-point price trades and with some of the broking software this last decimal is not shown, so the perception of a different price by one pip can be created, etc etc etc
Personally I feel these are non-genuine trades in terms of actually taking a stake in a company, add no value in terms of liquidity and should not be allowed, or should be charged retail brokerage.
