"Save backtest results" does not save parameter settings

[kdoren]

I have some strategies with lots of parameters, some of which are set by the optimizer, some set manually. I run the optimizer for some time period and generate results. The "Settings" tab shows the parameters which generated the results.

1) When I "Save backtest results" and then "Load backtest results", the results are loaded, but the "Settings" tab now shows the default parameter settings, not the settings that produced the results (very misleading). This is really wrong, there is no point in saving results without saving the settings.

2) After running the optimizer, the next thing I want to do is backtest over different time periods, using the parameters found by the optimizer. But selecting "Run Backtest" changes the parameters back to defaults. There really needs to be a way to save & load a set of strategy parameters, but I don't know a way to do this except by writing them down and typing them in, which is tedious and error-prone.

1) I just ran SampleMACrossOver with custom settings Fast=11, Slow=22, saved the results, openend a new SA, loaded the results and saw Fast=11, Slow=22 in the settings tab. What are you doing differently?

2) Thanks for your suggestion. We'll add it to the list future considerations.

I ran SampleMACrossover using the Optimizer with Fast set to "10;15;1" and Slow set to "20;30;1". I used 1 year of QQQQ, and default optimizer.

After running the optimizer, the "Settings" tab in the Strategy Analyzer showed "Fast = 14", "Slow = 30" (the settings found by the optimizer, which produced the results).

After "Save backtest results" and "Load backtest results", the results shown were the same, but the Settings now show the defaults of "Fast = 10" and "Slow = 25", which were not the settings that produced the results.

Thanks for clarification and reporting. This is a bug which will be fixed with next update.

Thanks.

When you "Load Backtest Results", the parameter settings which are loaded should become the current settings for the strategy loaded, or there should be a way to make them become the current settings (maybe right-click -> make parameter settings current).

This would give the ability to transfer settings from the optimizer to the backtester, and it's also the desired behavior for the backtester.

When evaluating a strategy, it's typical to run many backtests using different time periods and parameter settings (often small parameter changes to test sensitivity). Right now, if I load backtest results, I can see the parameter settings, but if I want to run a backtest using those settings, I have to type them all in. Quite a pain when there are a lot of parameters.
