My stops are part of my trading plan and risk management. If they are hit, the first I know about it is a notification that they have been automatically executed. Sometimes a spike down will take me out. It is just part of the risk.
However, the stops are based on historical volatility, not a fixed %, established by previous draw downs from a high, easily done by looking at a chart. The larger the stop%, the smaller the position size. I avoid the more volatile and less-liquid shares.
Currently 100% cash (after this weeks drops) and looking idly at factor based ETFs to possibly buy at some point ... I'm 10% down on the year (about 1/2 of that from not following the buying plan - I'm susceptible to being easily convinced by BB comments so I've learnt to try to not act on others views - so by extension my advice is ignore what I've written); would recommend Minervini for position sizing (and other things) http://www.minervini.com/blog/index.php/blog/optimal_position_sizing_excerpt_from_think_and_trade_like_a_champion_by_mar .
