This simple function can be used in Forex trading; it returns for a given symbol whether the specified currency is the base currency or the counter/quote currency.

The function is named "isbase", it accepts the currency name and it returns one if the specified currency is the base currency, minus one if the specified currency is the counter currency and zero if the specified currency does not belong to the current symbol.
For example, if you are working with the EURUSD forex pair, the following formula: isbase("USD"), returns -1.

This Forex function can be used in different scenarios:
Create a conditional trading rule that uses different rules depending on whether the currency tested is the base currency of the pair or not.
Create a composite index that creates an index for a particular currency. In this case, you must be able to detect whether the currency is a base currency and modify the calculation accordingly. For example, if you want to calculate the number of times the USD closed higher against other currencies, you should use "close > ref(close, 1)" in case USD is the base currency and "close < ref(close, 1)" in case the USD if the counter currency.
