This is a screenshot of using the percent price change with 1% wanted raise on sell. I get the same results using "NeverSellCheaper" and "SellAtDoubleFeeCosts". I'm just after an insurance that doesn't sell at a loss.

edit: I should also point out that the trades that are profitable *before* fees don't follow the 1% rule either. 1% of $5xx is around $5; most of those trades are within $2.

Thanks
