Purpose:
I want to use pandas-datareader to retrieve USDJPY data.

Steps to reproduce

1. res = DataReader('USDJPY', 'stooq')
2. res shows no data

Reason of Empty Data

1. The origin url is https://stooq.com/q/d/l/?s=USDJPY It returns data.

2. But because of ⬇️
   

   pandas-datareader/pandas_datareader/stooq.py

   Line 44 in b1247d1

   if not symbol.startswith("^"):

3. The url will be transformed to
   GET /q/d/l/?s=USDJPY.US

Solutions

1. Currently I couldn't figure out a way to make it.
2. I noticed 3398e41 this commit in the file pandas_datareader/stooq.py introduced many complicated statements that make it impossibe to do this kind of API Request.
