That double top was hard to resist both SPY & QQQ , quite a few double tops lately have been getting sold into in the stock universe EOG EBAY QCOM SNDK EXPE BIDU CSTR T DECK CREE LULU (and the most famous of all AMZN which gapped a/h to 284 for a perfect dubl top fade)
Some double bottoms have held recently like the 1320s for $GOLD that saw 50% pullback for the DUST & 50% bounce in the $NUGT etfs after incredible gains the other way.
See you are a specialist in the QQQ's which requires the whole bundle of macro FA analysis & TA so will follow along & bookmark this wise fellow's thread , you seem have made this you're baby.
