It would be hard to ignore this double top. However not a big one.
Btw a lot of indicators (Squeeze momentum, MACD) are still bullish or neutrals.
There is not (for me) enough strength in this sole pattern to short SPY and NDX, but you should think to close your long positions.

It reminds me this double top:
snapshot

It could bounce on the support as it could break trough.
Wait for a confirmation of the bounce if you want to long from ~430$.
