My understanding of how share trading works dates from the late 1980s and is now probably a bit rusty and may not apply to AIM. However, I thought that as long as a trade was within Size then it would take place within Spread. And I would have thought that 500 shares would be within Size for PHRM.L.
Can anyone here enlighten me?

There is a mechanism for late trades, corrections and special instructions (such as limit-sell orders) to be introduced to the dealing record. This means the time recorded on the transaction record may not me the time the transaction completed , meaning the price may be above or below the current trading price because of the time lag.
