Speed up execution suggestion. about reddit-stock-trends

That's a great idea @a904guy! In addition to this, I am also going to add a local static JSON/CSV containing all the tickers to verify the Tickers because api calls could be time taking. Suggestion by @Denbergvanthijs

Noticed I had a bug in the function, was calling tic not symbol. I've updated the example

History Caching to speed up Yahoo Financial section.

_symbols_history = {}
def yfTickerHistory(symbol, period = '1d'):
  if(symbol in _symbols_history and period in _symbols_history[symbol]):
     return _symbols_history[symbol][period]
  if(symbol not in _symbols_history):
    _symbols_history[symbol] = {}
  _symbols_history[symbol][period] = yfTicker(symbol).history(period)
  return _symbols_history[symbol][period]
