Styd,
1. It is rarely matched as majority of the trades are AT trades. For example a trader A wants to sell 200,00 shares in the open market at £2.00, he will not put 300,000 as it will drive the price down. He will lets say, do trades of 4000s and 10,000, he has 2 options, he can place 4000 on the offer side of the order book repeatedly till he gets filled (as 'bots' and will appear as Buys)or he can sell into the bid till he gets filled )will appear as Buys). In reality he will do different quantities and if he place 4,000 on offer (will show as a buy on trades)and someone buys 10,000 on a £2.00 limit order, they will get 4,000 filled off bid if traders sells (appear as Sell) and the rest will appear on the offer (if he gets filled will appear as Buy). If The trader say sells 10,000 limit at £2.00 will sell on the order book by taking off the remaining 6,000 (Sell)and his 4,000 (when someone buying off him will appear as a Buy)left will appear on bid and so on.....
UT is just an order matching process.
Black is just a colour indicating trades at the offer price (buy).
Unknown is maybe a mid price so system is unsure, remember all the Buys / Sells are indicative and uses bid and offer to determine it (if near bid will appear as Sell and if near offer will appear as Sell)
Sometimes a big O trade will then be slowly put through the market as AT.
Most people just do not understand and concoct basic idea of buy/sell by what they see as Trades, a bit of knowledge can be......
Hope you understand.....take time to absorb.
A good investor/trader takes both bullish and bearish opions, especially the correct ones rather that what they want to hear. Be flexible a bear and turn bullish and vice versa as circumstances/market is ever evolving
Good luck....coffee time for me
