nb. ( Why exactly did my risk go up? that was an assumption i used for convenience - not a corollary of some specific event.)
a. so you say stops define your risk - that is funny.
stops may define how much you lose (assuming no slippage) but they have nothing to do with risk. i guess all our misunderstanding comes largely from here...
separately, i believe hard stops are not an optimal way to control ones psychological shortcomings...it is better to learn to be disciplined. stops are a negative gamma for which you did not get paid theta...i like to work with mental stops which are continuously re-evaluated. they are based more on how the picture changed fundamentally. if i ever use hard stops i used them in a sense of time, i.e. i give myself some time (theta) and if it does not work i exit for whatever price.
to use a stupid example let's say that M&A deal in US is about to close , you are long/short and then something external happens (say tsunami or earthquake in asia) and the spread blows through your stop. you get whipsawed despite the probability of the deal closing is completely unrelated to the cause... good luck with that. the stops need to have some flexibility to it - which of course require a trader to be disciplined and not to abuse it. that's why i say that the initial strong confidence in trade is paramount - in your parlance it allows you wider "stops" and therefore more time to catch/consume the move.
c. about 15 years.
but in general if stops=trading works for you then great - it does not work for me...
