Both the DCA bot and the DCA trailing mode should have a way to add funds in the token form, where you can specify at what value you bought them. Example: Let's say i have BTC i bought manually at 24k long ago, and now the price is lower. I start a dca bot and besides the parameters that was set. I can add the held bitcoin, mark it to be bought at 24k and the bot will now know to calculate it to the average price, and will take profits next round based on the average that includes the added tokens. It might make the selling point higher than a bot without it, but when you take profit it's helping to get rid of old high price assets you hold
