How do you DCA out?

Obviously DCA into the market is the most straightforward and easy way to get into a position. But I feel that DCA out is rarely talked about in here (selling is unpopular to some I know).

Once you’re in a position, how do you take profits? DCA -ing out is likely the optimal approach since market timing is challenging – but how much do you sell off each time? Do you pull out 2%? 5%? At what intervals? How do you know it’s time to start?

This is primarily for those aiming to take profits (no disrespect to our steadfast HODLers – you have my admiration and support). What profit-taking strategy do you employ when DCA-ing out?
