Hi Clive, (Orcroft as well), Sorry about the wrong attribution.
There is one problem with
Defer actual buys until AIM stops buying.
which is at what point do you start monitoring with AIM? If the range high to low is short you have to play with the buy/sell safe to get a buy even if you start at the highest price. For example, Ford (F) has a 52 week range from $15.84 down to $11.10. Starting at $13.05 I bought at, using a standard 10% buy/sell safe and 10% of shares minimum trade you would not get a buy until you hit $10.88 using the online calculator. This is using 80% of $19575 to buy 1200 shares for $15660. With my spreadsheet I get a buy at $11.90 with a buy safe at 3% and 7.5% minimum trade. The next buy would be at $11.14 and the next at $10.84, an unlikely to happen anytime soon figure. So, where is it realistic to say AIM has stopped buying?
If you set buy/sell safe at 3% and minimum transaction at 5% you'd get a buy at $12.08 using the online calculator. The spreadsheet is a bit different and I'm not clear why.
Given this I prefer the two ticks up approach which would not require as long a wait, I would guess. At least that is what happened for me.
