Yahoo Finance parser was broken. So we created a new Yahoo Finace Parser. Now, the exchange rate is defined as the average value of close and open. Warning : getExchangeDataLowTraffic and getExchangeDataLowTrafficP returns error. Don't use now.

getExchangeDataArray(pair, callback, errorHandler): void

• pair : string or Array<string>
• callback : (Array<number>, pair) => any
• errorHandler : options (A default method is console.log(error))

Warning!

Bid and Ask can be returned undefined by some pair. If you find a pair that has errors, please write the pair at the issue.
