One question for traders, not analysts.

Lets say you open a long position, buying at 1500, with a target at 1600 in 5 days and a stop loss at 1450. After 2 days, price is at 1550. Is it a good thing to move up your stop loss, e.g. at 1500, or you don't touch it until target is reached or the 5 days are done ?
