Automatic retest task

a specialized task that will retest the strategy using the settings that were used in its most recent retest or build, but before that it will update all the data to include the most recent days.

It is useful when you have a set of strategies you want to retest periodically for example every week – Automatic retest will first download the missing data for the last week and makes a retest with the most recent data.

Update from version 144:

The Automatic Retest Task loads strategies from a source databank (which must already contain backtest results) and retests them across custom combinations of symbols, timeframes, and other parameters. Results are stored in a target databank based on configured Ranking/filtering options.

This is where you define the data flow:

• Source databank — the databank containing the strategies to be retested
• Target databank — the databank where retest results will be saved

Custom Data Tab

Controls what gets overridden during the retest.
Any setting left “off” retains the configuration from the original strategy.
Turning a setting “on” lets you specify a new value that applies across all retested strategies.

Trading Engine

Specify MT4/MT5 or TS/MC Backtesting Engine.
It is recommended to keep this set to the platform on which the strategies were originally built and tested.

Additional charts

You can enable that option in case of Subchart usage (Multi-Symbol Strategy)

Backtest Data Settings

Symbol — Stock Groups

Instead of listing symbols individually, you can reference a custom symbol group created in Data Manager → Stock Groups by wrapping the group name in square brackets.

1. In Data Manager, create a Stock Group named my_forex_group containing your desired symbols
2. In the Symbol field, enter [my_forex_group]
3. The task will automatically retest each strategy against every symbol in that group

You can also combine individual symbols and group references in the same field:

[my_forex_group], XAUUSD_M1_dukas

When multiple symbols and multiple timeframes are both enabled, the task tests every strategy against every symbol × timeframe combination. For example, 2 strategies × 3 symbols × 3 timeframes produces up to 18 result entries
