Is there a place, preferably, free where you can get premarket charts for a stock for the past couple of days or so? 1 min candlestick charts would be nice
For indexes, you may find free pre-market: http://money.cnn.com/data/premarket/index.html After hours: http://money.cnn.com/data/afterhours/index.html CNN also offers after hours quotes: http://money.cnn.com/quote/quote.html?symb=MSFT Their charts: http://money.cnn.com/quote/quote.html?symb=MSFT&time=5dy look continuous, so likely they are also plotting after hours, if not, there would be gaps at the open. Hope this helps
