==History==
[[Image:Hong Kong Exchange Trade Lobby 2007.jpg|thumb|200px|Hong Kong Exchange Trade Lobby]]
The history of the securities exchange began formally in the late 19th century with the first establishment in 1891, though informal securities exchanges have been known to take place since 1861. The exchange has predominantly been the main exchange for Hong Kong despite co-existing with other exchanges at different point in time. After a series of complex mergers and acquisitions, HKSE remains the core. From 1947 to 1969 the exchange monopolised the market.

==Trading hours==

The trading day consists of:
*A pre-opening auction session from 9:00 am to 9:30 am. The opening price of a security is reported shortly after 9:20 am.
*A morning continuous trading session from 09:30 am to 12:00 pm
*An extended morning session from 12:00 noon to 13:30 pm, also referred to as the lunch break. Continuous trading proceeds in specifically-designated securities (currently two ETFs, 4362 and 4363). Trading in other securities is not possible. However, previously-placed orders in any securities can be cancelled from 13:00 pm onwards.
*An afternoon continuous trading session from 1:30 pm to 4:00 pm
The closing price is reported as the median of five price snapshots taken from 3:59 to 4:00 pm every 15 seconds. In May 2008, the exchange also implemented a closing auction session to run from 4:00 pm to 4:10 pm, with a similar pricing mechanism as the opening auction; however, this resulted in significant fluctuations in the closing prices of stocks and suspicions of [[market manipulation]]. Initially, the exchange proposed limiting price fluctuations in the auction sessions to 2%; in the end, they removed the closing session entirely in March 2009.
Up until 2011, trading hours comprised a pre-opening auction from 9:30 AM to 9:50 AM, followed by continuous trading from 10:00 AM to 12:30 PM and 2:30 PM to 4:00 PM. The two-hour lunch break between the morning and afternoon sessions was the longest among the world's [[list of stock exchanges|20 major stock exchanges]]. A 2003 proposal to shorten the lunch break failed due to opposition from brokers. Another plan to shorten the lunch break to one hour was floated by the exchange in 2010; the morning session would then start earlier, run from 9:30 am to 12:00 pm, and the afternoon session from 1:00 pm to 4:00 pm, leaving the closing time the same as before. Justifications included bringing hours into line with China. Reactions from both brokers and the restaurant industry were mixed.
On 7 March 2011, the exchange extended its hours in the first of two phases. The morning session now runs from 9:30 am to 12:00 noon, followed by a ninety minute lunch break, and an afternoon session from 1:30 pm to 4:00 pm. Index futures and options now begin trading at 9:15 am, thirty minutes earlier than before, and close at the same time as before, 4:15 pm. On 5 March 2012, the lunch break will be cut to sixty minutes, with the afternoon session running from 1:00 pm to 4:00 pm.

The exchange first introduced a computer-assisted trading system on 2 April 1986. In 1993 the exchange launched the "Automatic Order Matching and Execution System" (AMS), which was replaced by the third generation system (AMS/3) in October 2000.
==Regulatory role==
[[David Michael Webb|David Webb]], independent [[non-executive director]] of the Exchange since 2003, has been arguing for a super regulatory authority to assume that role as regulator, as there is inherent conflict between its commercial and regulatory roles. In the meantime, he argues for improved investor representation on the Hong Kong Stock Exchange.
In 2007, the uproar by smaller local stockbrokers over the decision by board of directors to cut minimum [[Bid-offer spread|trading spreads]] for equities and [[warrant (finance)|warrants]] trading at between 25 HK cents and HK$2 caused the new board to vote to reverse the decision. The reforms were to be implemented in the first quarter, but was put back on the table following protests by brokers. Webb criticised the board for caving in to vested interests.
==Trading characteristics==
{{Ref improve section|date=June 2009}}
* It is perfectly normal for Hong Kong stocks of even well-known companies to trade at prices that correspond to less than HK$4 a share. A Hong Kong stock would not be considered a penny stock unless its price was less than about HK$ 0.50.
*Each stock has its own individual board lot size (an online broker will usually display this along with the stock price when you get a quote); purchases in amounts which are not multiples of the board lot size are done in a separate "odd lot market".
*There is a close-in-price rule for [[limit order]]s, which must be within 24 ticks of the current price. Individual brokers may impose an even stricter rule; for instance, [[HSBC]] requires limit orders to be within 10 ticks of the current price. Broker support for triggered order types such as [[Order_(exchange)#Market-if-touched_order|market-if-touched orders]] would allow placing orders further away, which would be sent to the exchange when the price condition was established.
