Dick, Here's one part of my experience in using a system to help 'let profits run'. I used to have a very difficult time letting things run. I am not able to spend all day following the market, but just the same found myself preoccupied with what my positions were doing because I didn't have an exit plan. Hindsight being what it is, it is clear to me now that I spent too much time deciding when to get in and too little time deciding when to get out. At least I have not generally suffered from the tendency to let losses run! But I used to over-react from almost any negative move and consequently miss out on upside. Much of my portfolio is shorter term now, largely because of market volatility. 2-4 days to 2 weeks on average. My favorite stocks I go back to time and time again. I stay away from illiquid stocks. Initially I wrestled with using indicators and interpretation to decide when to exit, but found that left too much to my imagination . Not good - still second guessing and that depends on where my head is at at the moment of analysis. Don't want that! I tried plotting a fixed percentage trailing stop and that worked better, although I still found myself second guessing it sometimes when other indicators appeared to confirm the overall move was still in my favour. Lately I have been experimenting with setting stops based on the volatility of the price action. With many of the stocks I follow, and I suspect this is a general truism, increased volatility to the downside is generally indicative of future downside price movement. Would certainly appreciation thoughts from others on this observation. Volatility seemed to be a good concept to base exits on, and based on some reading I did I decided to see how volatility based stops might help. Here's what I am plotting as an alternative to a fixed percentage trailing stop now. I'm reasonably happy with it, and find that I trust it enough to accept its signals. I'm sure it can be improved too. Stop based on Standard Deviation of Average True Range (SSDATR) (ref(Close,-1) - (( atr(PATR) + std(atr(PATR),PDEV,1)) * (1+K))) Is a WOW formula using variables: PATR - Periods Average True Range (30) PDEV - Periods standard DEViation (9) K - Correction Factor (.10) The default values I provided are only a starting point. My rules for interpreting: - close below previous days' SSDATR - GET OUT. - close below today's SSDATR - WARNING. I plot WOW Alertmarkers in different colours (yellow warning, red - get out!) directly on the chart. This leaves nothing to the imagination at all. It isn't perfect, but its not bad. The exits satisfy my need to based trading decisions at end of day (I travel a lot. Very hard to trade actively from a plane). I think it could be improved by factoring in volume as well. Something to think about. Suggestions welcome. Although I think over optimizing this stuff is probably a fools game too.Bottom line, I think it is critical to develop a *Plan* that *you* feel comfortable with and you MUST trust it. Until you do, you will always second guess what your charts tell you. In my case that has led to more and larger losses. Michael
