At the moment the script will take as one of its command line arguments

 

Refresh=n

 

Where n = the number of seconds.

 

This is multiplied by 1000 by the script and used to drive the WScript Sleep command which by definition is in terms of milliseconds.

 

The default is 0 which tells it to run continuously which would pretty well soak up a single core.

 

One could however put in a value of say 0.25 or whatever to make it at least somewhat intermittent.

 

I didn’t have any trouble getting it to run 10+ times in a second in continuous mode when I opted NOT to show the resulting AA Window but as I said this will pretty well soak up a single core.

 

Involving the Custom Backtester would I think take longer

 

Running a script like this and having it perform a Backtest so that one could get Performance Metric values for each bar is okay for the purpose of finding something that works for ones system …

 

However, a one iteration optimize will run significantly faster if one is only interested in performance metrics as of the last bar and this also obviates the need for the custom backtester as all AB performance metrics are returned to the AA window which can be exported by the script and then used however one wants programmatically.  I would think this would suffice for a production system where one would only typically be interested in those metrics as of the current or just closed bar.

Fred,

I assume from your "N millisecond" comment you don't see much of a
time penalty with running AA, to get some metrics, via a script?
