About cross currencies
For some currencies, there is no direct way to convert it to a particular second currency. Such currencies are referred to as cross currencies because the currency converter must cross it through an intermediary currency to obtain a conversion value. For example, suppose you want to convert from DKK to USD. Since there is no DKK/USD exchange rate the currency converter converts from DKK to EUR and then converts from EUR to USD.
Use the CONFIG_CROSS_CURRENCY_INFO parameter to specify the currency pairs that you will want to normalize and for which there is no direct exchange rate. The value of this parameter is a dictionary in which the key is the currency that you want to convert to the base currency and the dictionary value is the intermediary currency required for the conversion. The base currency is specified by the CONFIG_BASE_CURRENCY configuration parameter.
