Close or tight are context sensitive. 3 or 4 years ago, I knew people who where trading a similar method to me, and using stops half the size of the stops that I needed to use. Its all well and good them telling me that I should have halved the size of my stop, but it would been quite disasterous in my case as I wouldnt have benefitted on 1:2, 1:3, 1:4, 1:5 and above risk reward type trades that where actually responsible for most of my gains.
The point being, I was using as tight a stop as I could get away with at the time, and a tighter stop would have been detrimental.
As always on t2w, noone really acknowledges that a stop is one small component part of a highly synergistic and complex system, and actions that are beneficial in context A may be detrimental in context B
Dont get me wrong, I'm not advocating large stops but the size of the stop is of course irelevant, whats more likely to keep you alive, a 10 pip stop at 100 quid a point, or a 1000 pip stop at 1 quid a point ? the monetary losses are the same, but the frequency at which those stops will be hit are certainly not
