I suspect that corrective decline in $AORD has not finished yet. The current rebound (like DOW,SPX) is a counter-trend affair. If the wave count and measured target is correct (& to follow the trend direction for DOW), I suspect ASX may hit the secondary high (on B Wave Up) which is around 5400-5450 before the C wave down to 4900.
When is it going to happen for the decline to resume? probably, around Wednesday-Monday next week, in line with DOW, SPX which may push higher before the decline to resume.
