A flat ceiling with a rising floor — buyers paying up into the same resistance until it gives way. Trigger: A daily close above the flat resistance line, ideally on volume well above its recent average. Invalidation: A close back below the rising support line. Once the floor breaks, the pattern is void — the rising lows were the whole argument.
