Optimization

[staycool3_a]

Hi

Anyone in the nt community have any optimization functions that take under consideration unrealized gains? I’m basically looking to optimize the highest net pnl while having the lowest intra trade unrealized pnl

Thanks in advance

Hello staycool3_a,

Thank you for your note.

I’m unaware of any optimizations based on unrealized profits.

I would expect most cases you’d see max unrealized PL exceed net realized PL.

You may be interested in searching the net for risk adjusted profit metrics/formulas for what you’re looking to do.

Please let us know if you need further assistance.

Alan,

Is there anyway you can provide a super basic example for a optimization script? I can’t seem to figure out how to access strategy information within optimization functions. For example, it would be great if you can show me how to check if the previous trade is a winner or a loser. In the strategy script it’s as easy as

SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1];

And/or

GetUnrealized PnL

I have no idea how to implement something like this in Optmization functions. I looked around the forums and couldn’t find anything. Is there anything in the helpguide that I’m not seeing?

Hello staycool3_a,

I put together a strategy, SampleSmaCrossExposeVarToOptimizationFitness which has a public variable public double runningOTE=0;.

I put together an OptimizationFitness called alanTrackUnrealizedPlFromStrategy. The output of this is the runningOTE variable from the strategy.

When you run an optimization you can select, Optimize based on, alanTrackUnrealizedPlFromStrategy. When you run an optimization, the output in performance will be the runningOTE variable (marked with blue arrow).

Now you need to set up the strategy so that you track unrealized PL. You’ll have to modify the strategy by adding a secondary tick series.

You will also need to trace the max point from the time the trade was entered to exited, for example, you buy CL at 60.00, sell it at 61.00, but it traded up to 61.25, the var runningOTE would equal 1.25. This would be done in the strategy.

Please let us know if you need further assistance.

Thank you, Alan.
This will opened a whole different side of NT that was not opened for me. Thanks!

Alan,

I have two variables that I get by "counting"

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;
}

Anytime I try to divide these variables together, I get a zero. It shouldn't be zero. However, I can use these variables and divide other variables with them and I get the correct values. I can also print these to the output window and it gives me the correct values. But anytime I try to divide them with one another.... it gives me zero. Is this not allowed ?

These were INT variables. I changed them to double. And it seems to fix my problem.

Hello staycool3_a,

Great. When you finish the script if you cared to share it on the forum I'm sure other users would appreciate your contribution.

Alan, I'd be happy to share it. I'll do that this weekend after making adding comments and stuff. Thanks for your help!
