循环之后不会继续

Question

我有一段时间的循环循环。他们都按照预期的方式单独工作，但在第一次迭代循环之后，for循环的合并不会持续。

我无法弄清楚我的错误在哪里，因此我被卡住了。

import ccxt
from datetime import datetime
import pandas as pd
import numpy as np

exchange = ccxt.binance({ 'enableRateLimit': True })
now = int(round(datetime.timestamp(datetime.now())*1000))

data = []
symbols = ['ETH/USDT', 'BTC/USDT', 'LTC/USDT']
date = 1649196000000
for symbol in symbols:
    while date <= now:
        ohlcv = exchange.fetch_ohlcv(symbol, '1d', date, 20)
        data.append(ohlcv[0])
        # print symbol to check which symbol has been fetched
        print(symbol)
        # print date to view table
        print(data)
        # update date variable with date from last record
        date = data[-1][0]
        # increase date with one day to fetch new record
        date += 86400000

第一个循环运行直到date＆gt;现在。

然后开始循环的的下一个迭代开始。 <代码>循环被跳过，因为date＆gt;现在。
