Other considerations:
1. There is a bull butterfly pattern that could potentially pull price higher at pt3 (11500) level; however, with current market sentiment this seems unlikely.
2. The bear bat pattern will likely retrace bullish to above 13150 level after reaching pt1 (12200) before continuing strongly bearish trend.
3. If retest of 10500 occurs, then geometry of the large bear flag (measured from high at 16500 to 10500 low would indicate much lower target levels that 10500.
