I'm not interested in a system which performs for 40 years. The last 10 years I traded manually and survived because I am able to adapt. I designed my systems the same way. Those who are able to adapt...you know.
True. I suppose 40 years was a bit too long out of context. I was just thinking of the cycles the general markets have been in over a long time-frame. K, you win with 10 years.
Ninjatrader. I don't like it anymore (since Ninjatrader became a broker) but I don't have the time to get used to another product. Maybe in the future. I know the flaws and shortcomings of Ninjatrader, especially the backtest engine, but for now it does the job.
A backtest over a longer period of time would certainly be fun, but I don't have tick data for 40 years.
