Dear Support team, I would like to request a feature update for Backtest Master OL. I remember there used to be a spread setting function in the software, but now this option is missing. Besides, there is a display bug: After I switch the interface language to English and open this page, I can see options for spread and other settings. However, when I switch back to Chinese, only the commission option is displayed on the same page. Could you please add back the spread configuration feature and fix this display issue? Thank you.
