The 17,200 support level is key and long trades should be entered above the 17,320 (0 fib) levels. There is strong resistance around 19,000 so we should be expecting a pullback and setting our profit target to 20,000, selling a majority of our holdings as it is a major resistance point.
If 17,200 support fails we should look for entries on 16,000 based on whether or not the support holds. There is no need to panic and sell off as large picture + news hints at no reason of a complete breakdown.
It looks like 17,200 has held and the RSI and MACD seem to show this.
