"Hi, Does anyone know why the buy/sell price on the trading platforms to execute the shares do not reflect the prices shown on the charts?" ... a problem I picked up on 24 years ago when the first web based trading system came on line - I wrote to the LSe at the time asking for the exact data after figuring it out - but they declined for reasons.
The only "accurate" buy sell figures are AT trades at the time of execution by definition. AT trades only give a sample of background trading activity ... I tried once to make us of it but to no avail.
MMs can delay trades, and especially larger ones, while other MM trades are released with random intervals explaining why many are flagged as buy/sell incorrectly - LSE like other platforms simply make a guess at the time of positing based upon bid offer prices at the time of posting.
Bear in mind, that if a retail investor buys from a MM .. the MM has sold toy the retail investor so by definition every trade has a natched buyer and seller at the time of posting.
For daily trades, AT trade average price is probably the best indicator on level II - in my view - but that's view .. don't my advice.
