Features / TODO

• Fetch from yahoo
• Automatic local caching
• Slicing
• Plot candle sticks
• Random quotes * [x] Ticker 'pseudo' is an option to generate data without real quotes dependence (good for tests) * [ ] Explicit real quotes to sample from ('rnd-MSFT,APPL') * [ ] 'n' argument fecthes lazily within date interval
