Good points, x-or. I will keep an eye on the 30 RT figure with a view to lowering it if necessary, and I agree with you that it is only an upper bound which I may elect not to take advantage of, if I'm having an off day. I wish I could run a simulation to find optimal values for these parameters, but alas SOMP trading is not backtestable and the 38 days I've got under my belt hardly qualify for any meaningful statistical inference.
