NT7 to NT8 Optimizer Metrics / Fitnesses

[tmorgan4]

I would like to convert the custom optimizer types that another user was kind enough to share in this thread. (The original NT7 script is attached here).

Looking through the scripts I can see several changes from NT7 to NT8 but I'm stuck at the error on on 'GetPerformanceValue'.

Any help would be greatly appreciated!

Hello tmorgan4,

Thank you for your post.

Refer to the information at the following link: http://ninjatrader.com/support/helpG...on_fitness.htm

I would recommend comparing the NinjaTrader 8 Optimizer Fitnesses to the Optimization Types in NinjaTrader 7.

For example, Max Net Profit would use the following in NinjaTrader 7:

		public override double GetPerformanceValue(SystemPerformance systemPerformance)
		{
			return systemPerformance.AllTrades.TradesPerformance.GrossProfit + systemPerformance.AllTrades.TradesPerformance.GrossLoss;
		}

But in NinjaTrader 8 it would use the following:

		protected override void OnCalculatePerformanceValue(StrategyBase strategy)
		{
			Value = strategy.SystemPerformance.AllTrades.TradesPerformance.GrossProfit + strategy.SystemPerformance.AllTrades.TradesPerformance.GrossLoss;
		}
