Spread Out Quantity Document For Free

The way that SPAN calculates the spread margins on a portfolio is as follows:(Outright rate of leg 1 - Outright rate of leg 2) + Intra Spread Charge. The rates displayed on the Intra Spread pages are all of these rates with the exception where the formula would create a negative number.

You do this by subtracting the bid price from the ask price. For example, if you're trading GBP/USD at 1.3089/1.3091, the spread is calculated as 1.3091 ? 1.3089, which is 0.0002 (2 pips). Spreads can either be wide (high) or tight (low) ? the more pips derived from the above calculation, the wider the spread.

A measure of spread gives us an idea of how well the mean, for example, represents the data. If the spread of values in the data set is large, the mean is not as representative of the data as if the spread of data is small.

The variance and the standard deviation are measures of the spread of the data around the mean. They summarise how close each observed data value is to the mean value. In datasets with a small spread all values are very close to the mean, resulting in a small variance and standard deviation.

The term "bid" refers to the highest price a buyer will pay to buy a specified number of shares of a stock at any given time. The term "ask" refers to the lowest price at which a seller will sell the stock.

The bid-ask spread equals the lowest asking price set by a seller minus the highest bid price offered by an interested buyer. Electronic exchanges such as the NYSE or Nasdaq are responsible for matching bid and sale orders in real-time, i.e. facilitating transactions between the two parties, buyers and sellers.
