Seeking Open source backtesting engine ??

Quote from tradelink:

I can recommend tradelink... it works with IB as-is, as well as 12 other brokers. It's open source under LGPL and totally free :

Regarding backtesting :
* the tradelink simulator provides full tick-level simulation including l2/depth if available...
* very fast it plays back ticks between 200,000-800,000 ticks/second.
* It will do realistic portfolio playbacks, so it's easy to test basket or arbitrage strategies in addition to single symbol setups
* backtester execution engine supports limit/market/stop orders for fills out of the box
* There are three different off the shelf playback programs included in the package, and if you don't like those you can build you own GUI/app around the HistoricalSimulator component which provides the features above

Does IB have tick level historical data going back a long time?

It's certainly not something they give to the customers. Even "real-time" data from IB isn't tick data.
