Since the financial crisis of 2008, the stock market has changed not just through regulations, new entrants, and shifts of power, but also through the incredible advancement in algorithms which help automatize and improve trading. Algorithms are a set of instructions, which carry out a certain task. Rule for trading is Buy Low Sell High but when it comes to matching algorithm this rule would work opposite. Here Bid relates to Buyer and Ask relates to Seller In order to match Bid and Ask, Automated Systems in Exchange follows one algorithms wh Matching engines support different order types, such as a limit order or market order. Matching engines may have unique APIs, or use standard ones such as FIX APIs. The three largest futures match engines by contract volume are the CME Group 's Globex platform, NYSE Euronext 's Liffe Connect and Eurex 's 10.0 system release. A market maker is a broker-dealer firm that accepts the risk of holding a certain number of shares of a particular security in order to facilitate trading in that security (a security can be a stock, option, future or another asset).

For example, for a highly liquid stock, matching a certain percentage of the overall orders of stock (called volume inline algorithms) is usually a good strategy, but for a highly illiquid stock, algorithms try to match every order that has a favorable price (called liquidity-seeking algorithms).

Orders that can be matched are matched at a single price computed based on an algorithm set by SGX-ST. The computed price will be the opening price for the

The stock continued down but For example, for a highly liquid stock, matching a certain percentage of the overall orders of stock (called volume inline algorithms) is usually a good strategy, but for a highly illiquid stock, algorithms try to match every order that has a favorable price (called liquidity-seeking algorithms). Implementing the algorithm using a computer program is the final component of algorithmic trading, accompanied by backtesting (trying out the algorithm on historical periods of past stock-market
