Thanks for the replies, <br /> I have been using AIM again for about six months since finding the spreadsheet and re-reading the book. Still had some funds which ended up as Buy&Hold and are now AIMed again. <br /> The min/max share value safe was more or less born out of my question of where to set safe as some funds seem the have a larger swing than others, looks like a larger swing is also better of with a larger safe? <br /> Choosing min and max share value could be done by looking at the history I guess, it doesn't have to be precise, initially it was just meant to ballpark the safe... <br /> Shifting the safe gradually from buy to sell is done by excel so not much emotion in there. I must admit that there is a good chance of draining the cash quickly if the share value drops below the initial min share value... <br /> <br /> I did start to get the feeling that I overcooked my stew a bit, probably best to stick with normal AIM and leave this "project" for what it is ;) <br /> <br /> Thanks again for your opinions/advice.
