Python alpha_vantage module not returning all quotes for 'get_batch_stock_quotes'
By Emma Payne •
When using alpha_vantage to pull batch stock quotes for some reason get_batch_stock_quotes does not return the quote for symbol "ARRS". However, if the function is called using only "ARRS" in the symbols list, the quote is returned. I don't want to make several individual calls if I can get all the quotes returned in one request.
Here's the test code:
import pandas as pd
from alpha_vantage.timeseries import TimeSeries
import time
api_key = '12BHXD9VVA9M1PUM'
ts = TimeSeries(key=api_key, output_format = 'pandas')
stocklist = ("ARRS","PCG","AAPL","ACB")
STOCK=""
PRICE=0
data, meta_data =ts.get_batch_stock_quotes(symbols=stocklist)
for label, row in data.iterrows(): STOCK=row[0] PRICE=p=round(float(row[1]),2) print (STOCK,PRICE)Results:
$ python3 test8.py
PCG 11.67
AAPL 212.3
ACB 5.79If I just use stocklist = ("ARRS")the result is:
$ python3 test8.py
ARRS 31.64Why does this happen? Thanks in advance.

Why does this happen?
Unfortunately, this seems to possibly be something specific to your environment. Copying and pasting your code on Windows 7 with Python 3.7.4 yielded all four symbols with prices, as expected:
ARRS 31.64
PCG 11.03
AAPL 202.79
ACB 5.64
