**Similar to the [movie Wallstreet](https://en.wikipedia.org/wiki/Wall_Street_(1987_film)), Gekko delegates the dirty work of getting fresh data to Bud Fox. Bud Fox delivers the data to Gekko who uses this data to make investment decisions.**
Whenever Gekko works with realtime market data, it spawns a BudFox to fetch and transform the data for every market (exchange + asset + pair, for example: `bitstamp USD/BTC`). Bud Fox will keep on fetching data from the market in semi-realtime, turn historical trades into minutley candles (and make sure every minute of data has a candle).
BudFox exposes a stream of `candles` which are fed to Gekko.
## Advanced Usage
BudFox is a small part of Gekko's core that aggregates realtime market data from any supported exchange into a readable stream of candles. Example usage:
var config = {
exchange: 'Bitstamp',
currency: 'USD',
asset: 'BTC'
}
new BudFox(config)
.start()
// convert JS objects to JSON string
.pipe(new require('stringify-stream')())
// output to standard out
.pipe(process.stdout);
