Hi Larry, I use 5% of the equity side of the AIM account as the minimum for trading on most of my holdings. Yes, this essentially is like adding an extra 5% to the Buy/Sell Resistance (SAFE) value. However, on most of my stock holdings and the UOPIX account I've left the Resistance level at 10% on both sides and still use the 5% for minimums on top of it. There's always a trade off between frequency of transactions and the amount of profit realized in a "round trip" from a buy to a sell and back. If we lower resistance, we will trade more frequently, but for less profit on each trade. Of course, if you raised the resistance too high, you'd not have any trades. There's a point of diminishing returns that is different for each investment. Mr. L hit the mark pretty well for most investments. Now that computers are faster than when Bob Norman first wrote Newport it doesn't really matter as much, but Newport calculates your next buy and sell prices in both shares and dollars. If one uses just 1 share as the minimum and $1000 as the dollar minimum, then it makes Newport calculate all the possible share prices up to the $1000 value. You might notice it on an older computer, but not on a pentium machine. Back in the "Old Days" I used to try to keep the value of the dollar minimum and share minimum reasonably close to speed up the program. That 386 machine was long ago retired! Once you get a feel for a stock or fund, you'll "set and forget" the SAFE values and not tinker so much. BTW, I have Buy/Sell Resistance set at + or - 15% on some stocks. My feeling is that if they're volatile enough to get trade activity with a higher SAFE value, then why not take the corresponding larger profit per turn? Best regards, Tom PS: We went to St. Lucia last year. An amazingly beautiful place. Nice people. 3000' peaks above sea level. We didn't rent a car, just walked to places to eat and took tours to places that were too far to walk to.
