USD/JPY down 75 pips to 103.46

USD/JPY has broken below 103.50 as the stock market picture darkens on the flare up in worries about China.
There are bids around the 100-day moving average at 100.39 but they're not large. There are more at 103.00 and the Oct 10 low of 102.81 and Oct 6 low of 102.74.
Some options are running off in the 104.45/55 zone but earlier offers at 105.00 were never challenged with an intraday high of 104.64.
The critical support on my chart in the short term is 103.29. A break and close below would trace out an outside bearish reversal. Below that targets a challenge of support at 102.74.
