SPX EW Count

Here is an EW count that indicates there is not much room to the upside. If there is one more rally to new highs it could be W5 of an ending diagonal of a 5th wave extension, or W5 truncated at March highs. If this count is correct, W4 could be rather quick. Having alternation with W2, where W2 was a sideways, time consuming running flat correction. W4 could be a sharp correction making a simple ABC down to the 1750/30 level. I could be 100% wrong with this count and price keeps ripping to new highs.
