There is an old saying about no war plans survive the first contact with the enemy. Likewise, why would a static stop loss or target plan survive the addition of new information, i.e. data. So not so obviously, "new information" here has to be taken into context. If you are on a large time frame, e.g. hourly, then 15 second time frame does not apply. However if 5 or 10 minute probably does. So that is the conundrum. - One sets up (and submit) stops or targets in a trade, and "sticks to them" despite the new information. The Static method. - On the other hand, some don't set up (don't submit ) initial stops and targets and wait for the new data to set them, then they submit them when they become high probability of execution, based on the data. The Dynamic method. And lastly defining what constitutes "Non Relevant versus Relevant versus Actionable new information" is where the rubber hits the road. YMMV PS: New traders mostly end up with the static model because it is easier to understand and implement. And if you confuse the two or get into limbo between the two, that can be "bad badness"
