Stop loss

Hi Patrick, how are you? Please I have a question about buying add-on, so that means you have placed a new position right? If yes then where is stop loss when add more shares (open new position). For example ENPH entry was 326.40$ and stop loss was I guess around 320? And then you bot more shares at 336.95$, (open new position) so where is stop loss for this new position? Sorry if ths is silly question. Thank you.
