spi road map 14, page-6

morning acouch.........I have been following your roadmaps with interest but as yet dont have a complete understanding of them and what they imply. I have seen your brief explanation of the Line in the sand ....which is of course the last close of the spi.(I assume )(above we are looking for longs and below is shorts ) Just wondering if you might explain further the circled intersections and how u use them with your map etc etc .

Thanks Veedub
