    You are correct. As mentioned previously, a single input value is used for each individual strategy run; the value of Fast does not change over the lifecycle of the strategy and stays the same through the entire date range.


    If you would like these values to change within a date range I would recommend reviewing the walk forward optimizer, https://ninjatrader.com/support/help...e_a_strate.htm


    Please let us know if there are any other ways we can help.

    BTW:

    This is what I ended up doing to get the values and it seems to be printing the values being optimized at the "end" of each optimization itteration:

    Code:
    protected override void OnPositionUpdate(Position position, double averagePrice, int quantity, MarketPosition marketPosition)
{
      	
    if (position.MarketPosition == MarketPosition.Flat)
    {
		++strategy_trade_counts;
		Trade a = SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1];		
		if(a.ProfitCurrency>=0)
			++winning_count;
		
		if(a.ProfitCurrency<0)
			++losing_count;
		
		winning_average = SystemPerformance.AllTrades.WinningTrades.TradesPerformance.NetProfit / winning_count;
		losing_average = Math.Abs(SystemPerformance.AllTrades.LosingTrades.TradesPerformance.NetProfit) / losing_count;
				
		cum_profit =SystemPerformance.AllTrades.TradesPerformance.Currency.CumProfit;
	
    }
	
			if(Times[0][0].Date == new DateTime(2014, 12, 31))
			{			
			Print(string.Format("{0};{1};{2};{3};{4};{5};{6};{7};{8};{9};{10}",Time[0],strategy_trade_counts,winning_count,losing_count,winning_average,losing_average,PL_Ratio,Target,break_even,Tapper_increments,cum_profit));
			}
	
	
	
  
}
    I needed to calculate the expectancy for my strategy so I needed to calculate my correct winning, losing trade count etc and due to the issue I talked about in the other thread you're working on with me I had to manually count my trades. I added the print date statement to print the values at the end of my optimization iteration. The date has to be the last day of the date range for the optimization. I'm just not sure if the optimizer uses those values and runs them for the entire date range.

    -ps; I did a test; the optimizer iterations were 20; and the output printed that I was looking for is also 20 and then I tested the output individually in the strategy analyzer and the cum_profit matches the output I printed during the optimzition so the answer to my question is, "YES, each iteration runs through the entire period for a given variable the optimizer is testing."

    Thank you, Jessica.

    This is perfect.

    Another aspect of my question is:

    When the genetic optimizer is running, when it picks 5 for fast period... does it run this for the entire date range or does it randomly select random dates within the date range.

    Thank you

    Thank you for your question, staycool3_a


    It sounds like what you are after is processing during State.Terminated if State.Configure was reached. I have attached a NinjaScript example which accomplishes this goal, and produces the following output :


    Code:
    Last close was 2910.75 on bar 247449 for optimization over fast period 7

    I will address the genetic optimizer question in another post.

    started a topic Optimizer last bar

    Optimizer last bar

    Hi

    Is there a way to access the very last bar of an optimizer? I want to run an optimizer and optimize a variable

    Let’s say variable is .1;1;.1; at every single iteration once the optimizer has tested ... for example... “.1” I want to print out values from my strategy.

    I’m thinking if I run the optimizer from from 1/1/2017 to 1/1/2018... I can add a condition in my strategy to print those values if the day is 1/1/2018.

    But is there a way to access the last bar of optimizers iteration for each individual iteration of a variable? Also, using a genetic optimizer, does the optimizer run each variable from 1/1/2017 to 1/1/2018 data for each iteration of a variable or does it randomly test these values within the date range in small chunks?

    Basically, I want to see the FINAL results of my strategy from different possible values of a variable and then do further analysis.
