class Exchange \ Bitstamp

All implemented interfaces:: Exchange, ExchangeInformation

Implements some basic implementations of an Exchange. Assumes there is a single API call that can be used to list all exchanges and get all rates - #fetchAllRates(). (from SimpleExchange)

An Exchange does not provide conversion functionality; this can be done naively with #getLastTrade.

This is the base interface; other interfaces will provide additional functionality as necessary. (from Exchange)

Inherited Method Summary

Name	Description
fetchAsk($currency1, $currency2, Logger $logger)	Get the lowest price that a seller is willing to accept for trading the given pair (also known as the buy price), or `null` if there is none. (from SimpleExchange)
fetchBid($currency1, $currency2, Logger $logger)	Get the highest price that a buyer is willing to accept for trading the given pair (also known as the sell price), or `null` if there is none. (from SimpleExchange)
fetchLastTrade($currency1, $currency2, Logger $logger)	Get the last traded value for the given currency pair, or `null` if there is none. (from SimpleExchange)
fetchMarkets(Logger $logger)	Each of these pairs represents a market, e.g. 'btc', 'usd' These pairs can be in any (a, b) order, because we should (in theory) be able to swap last/bid/ask as necessary. (from SimpleExchange)
fetchRates($currency1, $currency2, Logger $logger)	Fetch all rates for a given currency, returns an array of (last_trade, bid, ask, volume). Some fields may not be present for a given exchange. `volume` is the last 24h volume. May also return additional fields. (from SimpleExchange)
throttle(Logger $logger)	This allows all exchanges to optionally throttle multiple repeated requests based on a runtime configuration value. The throttle time is selected from either the `exchanges_NAME_throttle` or `exchanges_throttle` config values, or three seconds; which is the time in seconds to wait between repeated requests. (from SimpleExchange)
