Fix OHLC test

[juancarlosqr]

Changes

• Resolves OHLC test failing #34:
  • For some reason calling the OHLC endpoint with AAPL returns empty data but for T it doesn't. I guess it might be because they are in different exchanges and/or as the docs describes:

Some stocks can report late open or close prices
