This tab contains the crème de la crème of the top strategies. These are the best 20 strategies from all backtests you did in this strategy; be they standard (manual) backtests, or Divine Engine backtests (local and cloud). This tab is located at the bottom-middle of the Backtest Strategy Page. Here you can load the top strategy's parameters and make it the active strategy.
The top 20 are picked based on their final Fitness Score (in-sample), regardless of the criteria they used as Fitness Functions. Such Fitness Score (in-sample) can be seen from the Divine Engine Results Tab:
If it's a standard backtest, the Fitness Score isn't listed anywhere; you can only guess based on the Fitness Functions criteria you set (on the Backtest Parameterization Panel) before you pressed the button. Yes, you may need to to display that panel (and adjust the Fitness Functions), despite just doing a standard backtest.
Note, if you do another backtest, the result(s) may end up here thus replacing the previous crown holders; as the list is capped at 20 at all times. Now, let's discuss the various columns there:
1. Type – This shows the type of backtest that the top strategy was created from.
It can be either:
2. Rank – This shows the rank of each top strategy.
The strategy with the highest “Fitness (IS)” score has the top rank, and it goes down from there. By default, the whole 20 strategies are sorted top to bottom based on this Fitness (IS) Score.
3. Load Parameters – These buttons load the parameters of the top strategies.
The top strategy's rules, filters, parameters, portfolios, and values (in short, anything on the Rules Area, including the Backtest Parameterization Panel) are loaded as the active strategy, very similar to loading a top strategy from the Divine Engine Results Tab. And you can load a top strategy while the cloud backtest is still running.
Note, if your strategy is currently in read-only mode, you can still load any of the top strategies here, by confirming to override the read-only mode from the ensuing dialog:
Once done loading the top strategy (or even customizing the strategy further), you can restore the read-only mode by clicking “Restore read-only mode…” (on the Strategy Panel) or navigate away to another strategy.
4. Fitness IS/OOS – These columns show the top strategies' final Fitness Score.
“Final” means the metrics score (those used as Fitness Functions, like CAGR, Max Drawdown, etc.) are aggregated & normalized into 1. These columns are for both the in-sample and out-of-sample Fitness Score.
5. Metrics Score – These columns show the individual metrics' score of the top strategies.
By default, the metrics shown here are those Fitness Functions you listed on the Backtest Parameterization panel:
You can add other metrics' column with the “Manage Columns” dialog; click the button shown below:
Here you can search and select any metrics, be it their IS (in-sample), OOS (out-of-sample), or AS (all-sample) column:
Should you wish to hide any columns, simply deselect them from that dialog and press OK. Those metrics used as Fitness Functions are grayed out (in italics), as their columns must always be shown. If you wish to remove them, delete the Fitness Functions first, then deselect them from this dialog.
6. Test Date – This shows the date & time the top strategies were born (backtested).
These are the local dates & time on your computer.
7. Select Backtest Source – Clicking these buttons selects the Backtest Item a top strategy belongs to.
If the top strategy comes from a standard (manual) backtest, its backtest record (item) will be selected on the Manual Results Tab:
But if the top strategy resulted from a Divine Engine backtest, its Backtest Item will be selected (light-gray highlighted) on the Divine Engine Results Tab:
This is useful, for example, if you want to check the top strategy's siblings, and decide whether some of them have more convincing performance than the top strategy itself.
8. Delete Buttons – These buttons delete top strategies.
Once removed, the top strategy exists neither in here nor in its respective Backtest Item; it's gone entirely from history, and another will take its place in the top 20. This is useful to delete garbage strategies; let's say the Fitness Functions used were nonsensical hence it doesn't deserve a top 20 due to inflated Fitness Score. Therefore your collection of top 20 strategies stay neat and easy to find.
