Which method is called only once at the end of the script?

[Jeffsg605]

While doing a back test on a particular instrument, my strategy keeps a count of a certain number of events (in this case, gaps). Once the strategy finishes running on this instrument, I would like to print this data to a file? Which method should I put that code in?


I've tried putting it in OnStateChange (State==State.Terminated) but it appears I lose the value of my variables. Otherwise I'm not sure where it should go.


So my question should be, which method gets called only once as soon as a back test completes?


Thanks!

Hello Jeffsg605,

Thank you for your note.

You could use streamwriter to save your trade information to a file.

See the following section of our helpguide.

https://ninjatrader.com/support/helpGuides/nt8/en-us/?using_streamwriter_to_write_to.htm

If you use Streamwriter in State.Terminated, does it save the information to the file as desired?

I look forward to your reply.

Hi Alan,


Thank you for responding but I think you missed my question. I don't need help writing to a file. As I stated in my initial question:



"I've tried putting it in OnStateChange (State==State.Terminated) but it appears I lose the value of my variables."


The value I want to keep track of has already been reset to 0 in State.Terminated. So to repeat my question, which method gets called only once as soon as a backtest completes?


Thanks.

Hello Jeffsg605,

I’ve attached a sample strategy which when you run in the strategy analyzer, upon completion, will print to the output window the value of a variable which has 1 added to it on each OnBarUpdate. So for example 300.

Instead of printing, you could have this value written to a file.

Please let us know if you need further assistance.

Thanks, I'll give this a try tonight. For the time being, I got it to work by just checking to see if the date of the backtest is today's date (or the last tradeable day). If it is, then I write my file, otherwise, I continue. This is a little cleaner though, thank you.
