Differences in prices and tick values are necessary for the arb to occur. The extraction of elements from a matrix can be accomplished via the use of the [,] operator. For random variables that take on discrete values, we use probability mass functions to denote the probabilities on the y-axis and the values of the random variable on the x-axis. Arb locals: Local traders whose sole purpose is to take advantage of the arb opportunities between the price in the pit and the price trading on the electronic markets.
