Currently HXR Trade does not support backtesting of DCA robots, but supports forwardtesting using paper trading, which is usually more reliable than the results of backtesting.
Of course, if you still want to backtest your robot or strategy, you can search for DCA related scripts in the Tradingview community for backtesting.
Tips:
The backtest results can only be used for reference, and historical profits do not mean future profits.
Also, some scripted strategies use future functions, and such strategies often have good backtested profit curves, high win rates, and low drawdowns. Then it's not actually reliable, please be careful 😣!
