fetchOHLCV (symbol, timeframe = '1m', since = undefined, limit = undefined, params = {}) 你可以调用CCXT统一API的fetchOHLCV / fetch_ohlcv方法获取指定交易对符号的OHLCV烛线图数据。JavaScript示例代码:let sleep = (ms) => new Promise (resolve => setTimeout (resolve, ms)); if (exchange....
使用ccxt查询历史数据,使用exchange.fetch_ohlcv函数。 ohlcv: open, high, low, close, volume. 此处我们演示获取日线数据。 此处由于每次从api获取的数据条数有限,需要我们多次获取。 symbol = "BTC/USDT" time_interval = '1d' since_time = datetime(2021, 1, 1) to_time = datetime(2024, 8, 1) df...
ohlcv = exchange.fetch_ohlcv(symbol, frequency, since=since, limit=bars) ``` 转换数据为DataFrame 📊 接下来,我们将获取的数据转换为pandas DataFrame,这样更容易进行分析和可视化。 ```python df = pd.DataFrame(ohlcv, columns=['timestamp', 'open', 'high', 'low', 'close', 'volume']) df['...

有些交易所没有提供任何OHLCV方法,为此ccxt库将利用公开交易模拟OHLCV烛线数据。 在这种情况下你会看到交易所对象的has['fetchOHLCV']属性的值为emulated。 但是,由于交易历史通常都非常有限,模拟的fetchOHLCV方法只能涵盖最近的信息, 因此只可以作为没有其他可选项是的备选方案使用。
