为for循环中存在的值运行多个无限循环

Question

我正在尝试对csv文件/数据库中的所有ticker值运行无限循环。 我打算用一些基本的示例代码来提问，但是我认为提供上下文帮助理解是很重要的

如果我以当前的方式运行它，将在下一次之后检查一个ticker。我要同时检查所有的股票行情

这是我正在从事的项目的当前代码：

import pandas as pd
import numpy as np 
import yfinance as yf 
import datetime as dt 
import matplotlib.pyplot as plt
import yahoo_fin
from pandas_datareader import data as pdr 
from scipy import stats
from scipy.stats import linregress
import scipy.signal as sc
from yahoo_fin import stock_info as si
import winsound
from ib_insync import *
from multiprocessing import Process


with open('sellerdf.csv', 'r') as csv_file:
    csv_reader=csv.reader(csv_file)

ib=IB()
ib.connect('127.0.0.1', 7497, clientId=1)


while True:
    try:

        for line in csv_reader:

            ticker=line[1]
            quantity=line[2]
            channel=line[3]

            pricebefore=si.get_live_price(ticker)

            time.sleep(60)

            priceafter =si.get_live_price(ticker)

            if priceafter>pricebefore:

                stoploss = priceafter *0.99

                time.sleep(20)

            else:

                stoploss=pricebefore*0.99

                time.sleep(20)

                new_currentprice=si.get_live_price(ticker)
            
            if channel*1.01 > new_currentprice < stoploss:

                order = MarketOrder('SELL', quantity)

                stock=(ticker, 'NYSE', 'USD')

                ib.qualifyContracts(stock)

                trade=ib.placeOrder(stock, order)

                trade.log()

                trade.orderStatus.status()
