Since you have been so kind to a demented old man (presumably because you have had so much practice across his kitchen table), I will share with you my primary method for system development. I continually confabulate absurd trading ideas, code them, and present them to ET as foolishness. If ET hates them, finding them to be outrageously counterintuitive, I continue development. You remember my thread "Volume Leads Price"? See the vertical red line on the attachment of today's NQ.
