Forex Symbology

The symbology for forex symbols is a six-character symbol consisting of two three-character pairs. The first three-characters is the base currency and the second three-character is the counter currency.

For example, EURUSD is the symbol for trading Euros that are calculated in US dollars. In another example, USDJPY, this forex symbol trades US dollars that are calculated in Yen. The use of symbols based in a different currency from your trading account may involve currency conversion when calculating P/L. This is especially important to understand when using strategies with these symbols. For more information, see to Currency Conversion.

When forex positions are held overnight, including in strategy backtesting, a rollover adjustment is made on long and short positions.

 In the Symbology expressions given in this section, [x] denotes a parameter that should be replaced with a value. The brackets ([ ]) are not a part of the expression. For example, [Symbol root] should be replaced with a symbol, such as ORCL. Items in italics are optional.

Extensions After Decimals

The data in the chart for a forex symbol is the Bid stream, and you can plot the Ask stream using a symbol extension of .A, e.g. EURUSD.A, or the Midpoint between the Bid and the Ask (Bid + Ask/2) using .M, e.g., EURUSD.M.
