Previous Resistance is Now Support
An object in motion is likely to stay in motion, and usually in the same direction unless something bats it back. This break-out today of an ascending triangle on the daily $SPY, while huge and in need of a rest, is more likely the start of a grinding rally further rather than a top as market has been bullish/neutral, consolidating recent moves, for a number of weeks.
Previous resistance is now support around 142.
Could this be a top? Sure, but we can't know that until we see significant distribution. Small pull-backs are likely and will consolidate this move in a healthy manner.
