Foreign exchange markets also have active algorithmic trading, measured at about 80% of orders in 2016 (up from about 25% of orders in 2006). [36] Futures markets are considered fairly easy to integrate into algorithmic trading, [37] [38] with about 40% of options trading done via trading algorithms in 2016. [39]
High-frequency trading (HFT) is a type of algorithmic trading in finance characterized by high speeds, high turnover rates, and high order-to-trade ratios that leverages high-frequency financial data and electronic trading tools.
Such manipulations are done typically through abusive trading algorithms or strategies that close out pre-existing option positions at favorable prices or establish new option positions at advantageous prices. In recent years, there have been a number of algorithmic trading malfunctions that caused substantial market disruptions.
Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.
If we start with an initial solution made with a greedy algorithm, then the average number of moves greatly decreases again and is ; however, for random starts, the average number of moves is ( ()) . While this is a small increase in size, the initial number of moves for small problems is 10 times as big for a random start ...
All the itemsets of size 1 have a support of at least 3, so they are all frequent. The next step is to generate a list of all pairs of the frequent items. For example, regarding the pair {1,2}: the first table of Example 2 shows items 1 and 2 appearing together in three of the itemsets; therefore, we say item {1,2} has support of three.
