Specifying request options

Optionally request options (such as a proxy) can be specified by inserting an extra parameter just before the callback:

var httpRequestOptions = {
  proxy: 'http://localproxy.com'
};
 
googleFinance.companyNews({
  symbol: SYMBOL
}, httpRequestOptions, function (err, news) {
  // Result
});
 
googleFinance.historical({
  symbol: SYMBOL,
  from: START_DATE,
  to: END_DATE
}, httpRequestOptions, function (err, quotes) {
  // Result
});
