When you select Default Auto Sell inside a preset, you are instructing the bot to use your main Auto Sell settings that were configured outside of the preset.
This means the preset will not have its own custom Auto Sell rules — instead, it will automatically follow the default Auto Sell parameters you have set globally in the bot's main settings.
Use Default Auto Sell if you want all your presets to maintain consistent profit-taking and risk management strategies without having to customize each one individually.
