按交易对查询实时行情

要查询指定交易对/符号的实时行情数据，调用fetchTicker(symbol)方法。

JavaScript示例代码：

if (exchange.has['fetchTicker']) {

console.log (await (exchange.fetchTicker ('BTC/USD'))) // ticker for BTC/USD

let symbols = Object.keys (exchange.markets)

let random = Math.floor (Math.random () * (symbols.length - 1))

console.log (exchange.fetchTicker (symbols[random])) // ticker for a random symbol

}

Python示例代码：

import random

if (exchange.has['fetchTicker']):

print(exchange.fetch_ticker('LTC/ZEC')) # ticker for LTC/ZEC

symbols = list(exchange.markets.keys())

print(exchange.fetch_ticker(random.choice(symbols))) # ticker for a random symbol

PHP别忘了正确设置时区：

if ($exchange->has['fetchTicker']) {

var_dump ($exchange->fetch_ticker ('ETH/CNY')); // ticker for ETH/CNY

$symbols = array_keys ($exchange->markets);

$random = rand () % count ($symbols);

var_dump ($exchange->fetch_ticker ($symbols[$random])); // ticker for a random symbol

}
