Agree. Looking at a medium dive within a week. Reasoning: cycle, a super extended harmonic, broadening wedge at top, significant low volume. VXX already show unusual buying at low yesterday, market is expecting a dive.
imo you cannot compare 1-1 the SP with AUD/USD. If your looking for a short on S&P an opportunity might come later this week when we go a bit more down. Last week we could have a hanging man on the weekly chart. For a downtrend it should be confirmed with a red candle this week.
