cheltspy... what the heck are you talking about ?
I said irrespective of where your broker gets the stock from, its FSA and LSE regulations to DISPLAY the trade - Whether its a broker to broker trade (flagged as B) or protected trade (T), or conditional trade (C), or the 34 other different types of trades. ALL trades have to be shown on the screen, its just upto the broker which screen that its displayed via (LSE or Virt-x). Thats part and parcel of transparency which is the corner stone of western stock exchanges.
