My broker (where I currently have a paper account) is telling me that I can purchase market data for LSE (London Stock Exchange).  I have done this on a trial account and I see a wealth of data i.e. candlesticks.  Where is this information pulled from if LSE is not aware of all transactions? 

It'll just be whatever's reported to the LSE. The dark exchanges use the LSE's prices as a benchmark and won't vary much from it. "Candlesticks" is just a type of chart constructed from the available trade data. There's nothing special about one.

Thanks.  So data on dark pools/ECNs/ATSs is unknown to LSE making the LSE data useless - I would have to pay tens of pounds for this after the trial expires? I have read that brokers offer CBOE data to paper accounts and something more to non-paper accounts.  At this point I am trying to understand what that something more is.  Maybe that something more shows everything from ECNs and dark pools - after the trade has taken place?

Thanks.  But where is the data generated from? I assume it is just generated from LSE with lots of transactions (prices and volumes) missing because they were traded inside an ECN/ATS/dark pool etc.  Therefore the paid for real time data is rubbish?

It isn't rubbish - the LSE is the benchmark for pricing -  but you might not see every transaction. IIRC most technical analysis cares far more about the price than volume so it shouldn't be a major problem. Going by your OP this is just an academic exercise anyway.

If somebody wishes to offload a sizable line of stock in a particular security. Then this occur at a significant discount to the current market price with any number of partcipants. The security in effect being placed.

It is an academic exercise partly - trying to learn a new skill as well.  Do most/all transactions eventually get reported to LSE then e.g. in the case of a dark pool this could be some time after the transaction is filled?
I read somewhere that if you have a free account then most brokers offer CBOE data, which has missing candlesticks and is not real time i.e. 15 minute delay.  What is the alternative to CBOE?
I have highlighted the key points of this comment.

I don't know, no doubt the LSE will tell you on its website what all of the rules are.
I'm not sure what "CBOE data" is but if it's academic why do you need real-time prices? As I've said before, there's nothing special about candlestick charts: you can see them for free at e.g., Yahoo Finance. You don't need a broker to give you real-time prices or charting. I don't know them all but you can go direct to third parties like Advfn or Digital Look/Sharecast. Obviously you'll need an account and will probably need to deposit at least a little money but you can get a one-time real-time price with a broker by asking for a quote to buy or sell.

 Although you won't see the LSE indicated bid and offer prices, Google finance will give you real-time prices of the last trade.

Edit: Trading212 might give you a lot of what you want. I'm not sure what the delay on prices is but it offers candle etc. charts which will update automatically over time for free.

CBOE possibly Chicago Board Options Exchange?

If you are talking about CBOE in terms of an exchange, than their are many other options, a stock might trade a dozen or so exchanges around the world, although the price will be very similar, give it or take liquidity issues.

I was reading about Tradecho recently (https://www.lseg.com/markets-products-and-services/our-markets/london-stock-exchange/equities-markets/raising-equity-finance/market-open-ceremony/london-stock-exchange-welcomes-tradecho).  This is telling me that MIFid2 transparency means that LSE is reporting on all shares that are traded i.e. even those that are Off Book (in LSE terms)v i.e. through a Systematic Initialiser e.g. dark pool, ECN, ATS etc.  I am not sure though and would appreciate clarification.
