in case that the market turns against me - I become an investor until I spot an opportunity to carry out a correctly calculated DCA (I've done it enough times that now I can be fairly certain when will it move in my desired direction and that the movement will be enough to recover and close the deal in green).
Stoploss is for trading.
DCA is for investments but when you are trading fundamentally good assets then you can still go for DCA. When there will be no chance of bounce back, getting into DCA will not make any sense.
For DCA, you must need available capital. By exiting at stoploss, you are making your capital available for next trade.
