Ruboid, thank you for your kind reply. Like many people, I've had plenty of unsolicited mail from Streetwise and never bought anything from them. I admit I fell to temptation owing to the money back guarantee (and all evidence suggests they do honour this). On receiving the manual I did think right away that it was an old strategy, nothing new, and the author was simply recommending a bot from which I'm sure he receives some sort of affiliate payment. Having said that, it performed quite well in test mode and there's a couple of tweaks I'd make. If only I could get it on Market Feeder Pro. Thanks again.
