Problem backtesting

[spacebalts67]

Lately when I try to backtest a strategy, no matter what timeframe I use, I only get data from 6/11, 6/12, and 6/23. These are strategies that should create roughtly 50-70 trades/day and there is no way I would only get results for these 3 days. I am connected to gain capital when I do this. Any Idea why it would be doing this?

It is because GAIN does not provide historical data and you are most likely just running with data stored in your database. Please see this: http://www.ninjatrader-support.com/HelpGuideV6/helpguide.html?HistoricalData

Is there a free service that provides historical tick data?

OpenTick provides free, but I don't recall if they are still open for registration. Various other vendors are available on that link provided earlier. You may need to shop around to see one that fits your needs. You can get daily data from Yahoo for free though.
