I'm looking to backtest a system that requires historical intraday (2mins) candles for 250 trading days or more for the SPYdrs. I'm doing a Simple MA overlay that requires 2min periods to generate the MAs. I've been searching the web for a good site and the best free java based charting site I've been to is at prophet.net. It gives me 20 trading days of intraday data. However, that sample size isn't quite enough for me to come to a statistically significant conclusion. I only get 16 buy/sell signals from that one month of data. The historical data I have access to from First Alert (thin client) doesn't have enough intraday data for my back test. Just wondering if anyone has any suggestions. To anyone with Qcharts: could you load up SPY on 2 mins and let me know what date it goes back to? Thanks. DNAJ65000
