From your screen, you have to know a few terms. Take for example the stock "Axiata".

B-Q = Buy Queue = 10934 lots
--- this means that people are queuing to buy (a total of 10934 lots)
--- At what price? At RM3.76 (see "Buy" column)
--- If you put in an order to buy at RM3.76, say 25 lots, then the total B-Q = 10934 + 25 = 10959

S-Q = Sell Queue = 433 lots
--- this means that people are queuing to sell
--- At what price? At RM3.77 (see "Sell" column)

Can you buy "Axiata" stocks immediate at that time? Yes, instead of waiting to queue to buy at RM3.76, you can buy straight away at RM3.77 as people have queued to sell at that price.
- say you put in an order to buy 30 lots at RM3.77
- the transaction will go through as there are people waiting to sell at that price
- Once the transaction is done, the S-Q = 433 - 30 = 403 lots left waiting to be sold

You can see the queue in more detail by double clicking on "Axiata" and then select this icon to see more:

Note : 1 lot = 100 shares

1) Yes, you have to wait for your queue. It is something like standing in-line to buy your shares at RM3.76. You can only buy it when you turn comes.
- alternatively, as mentioned above, if you don't want to wait to buy, you can key-in to buy at RM3.77. As there are nobody waiting in-line to buy at RM3.77, your transaction will take place almost immediately.

2) That is correct. You have to wait your turn at RM3.77.
- Another example, if one guy straight away key in RM3.77 to buy 500 lots, he will have snapped up all the 483 lots (in the S-Q column at RM3.77), leaving 17 lots left not bought in the RM3.77 B-Q column.
- If you are successful in selling your stocks, you will only get your money after T+3 (same as buying)

3) Errmm... not too sure about that as I never tried the game.

Answered above in blue.

Answered above in blue.

Errrmmm... there's nobody queing up to sell at 0.135 or 0.130 ma.... how to buy?

Can still buy 0.135 or 0.13 but will be in queue and not matched immediately.
Queue order is open until someone dispose/sell at 0.135.

1) Errmm.. why are you concern from where you bought the shares from?  To answer your question, it is as explained earlier. You trade by Q. Assuming that A (100 lots) queue first, then B (50 lots), then C (100 lots) then D (50 lots), if you bought the shares from their Q by 200 lots, you would have bought 100 lots from A, 50 lots from B and 50 lots from C. This is done automatically and does not need any effort from your part. C would have 50 lots left to sell. If another guy comes to buy 10 lots from that Q, it would be from C's 50 lots (as C is now at the front of the Q because A and B already sold their shares), 50-10 = 40 lots left from C. Remember that we're talking about people queueing up to sell at a certain price point.

2) Haha, that's the transaction that was done. In that picture, 600 lots were sold at 0.415 at 4:50:05 pm. Red colour for sold, green colour for bought.
