Improve ticker handling for multiple tickers

[StephanAkkerman]

We could make it quicker because many libraries support querying multiple tickers at the same time: yahooquery:

from yahooquery import Ticker

symbols = ['fb', 'aapl', 'amzn', 'nflx', 'goog']

faang = Ticker(symbols)

faang.summary_detail

tradingview_ta also supports it, ccxt might, coingecko?

import requests

apiBase = "https://query2.finance.yahoo.com"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64)"}

def getCredentials(
    cookieUrl="https://fc.yahoo.com", crumbUrl=apiBase + "/v1/test/getcrumb"
):
    cookie = requests.get(cookieUrl).cookies
    crumb = requests.get(url=crumbUrl, cookies=cookie, headers=headers).text
    return {"cookie": cookie, "crumb": crumb}

def quote(symbols, credentials):
    url = apiBase + "/v7/finance/quote"
    params = {"symbols": ",".join(symbols), "crumb": credentials["crumb"]}
    response = requests.get(
        url, params=params, cookies=credentials["cookie"], headers=headers
    )
    quotes = response.json()["quoteResponse"]["result"]
    return quotes

credentials = getCredentials()
quotes = quote(["GOOG", "TSLA"], credentials)
print(quotes)
