Here is a further thought. If the harmonic pattern is big in terms of its size, then it also takes long time to confirm the pattern formation. In turn, repainting or non repainting confirmation is typically fast with small harmonic pattern. In addition, repainting happens in any technical indicator. But the repainting only affect the last candle bar most of technical indicators. For example, as new price arrives, the moving average indicator will keep changing its value for the last candle bar. As the repainting of ZigZag indicator can affect the last swing point to the previous swing point, ZigZag indicator is affected by repainting over many candle bars from last swing point to previous swing point. Hence, you might feel the repainting more in the ZigZag indicator.
