Simplest application of FLIR. Draw any two intersecting trendlines; find any inflection to left of intersect; use line tool to measure height between trendlines at that inflection point; clone that vertical line and drag to right of intersect 'til it fits between the two trendlines, and that should mark another inflection. WARNING: whipsaws are possible, but right now it looks like 7340 resistance, 7200 support.
