Hi,
I have a backtesting framework set up and ready to go. It can backtest different variations (parameters) very quickly, using multi-threading. You can do thousands of variations in just a few hours. You get a report of each and every trade made, separated by parameter variation, ready for analysis. It's very powerful; however, it is not ninja trader, it's in java, originally built for Interactive Brokers.
If you are interested to backtest on my platform, then we can tackle implementing the automated trades on NinjaTrader later once you have identified a successful trading strategy. I'm happy to complete that also, but the benefit here is that this platform is ready to go for you and you can have results right away.
