Regardless of the size of the stop-loss?
regardless,

if talking about trading the same instrument and trader chooses to trade in certain periods accepting the volatility thereof, then he must choose the size for those games
looks like you u actually agree with me that size matters,
and you just trying to adjust it accordingly to the fluctuating stop-losesi assume the size for the worst case scenario ( the biggest stop-loss possible in playing periods), and i play it from the beginning to the end with the same size
the OP is less concern with stops he wants to increase size (and profits) with market going his way
personally i do not have time for all those manipulations i concentrate on make sure i do not miss something while situation develops
with the growth of the account trader then can gradually increase size of his position
