I haven't been investing for that long and at the most I've seen a triple top. I don't know if I interpreted this wrong but I'm seeing five wave crests. Assuming I'm right, if triple tops are strong and quadruple tops are stronger, quintuple tops would be even stronger. With this being said, if a breakthrough happens in the NDX/SPX, we could see the NDX start to decline relative to the SPX.
it is also important to note that on the daily chart of NDX there is a H&S formation, so if there is a breakdown we could see a up to a 5% correction.
