Currently, there is room for more growth towards $17 700 - $18 000 zone. This is suggested by wave structure, which looks incomplete - final 5th wave is due. The problem with this chart is that the segment from $17 270 to $15 960 is ambiguous. That's why I'm not sure that 5th wave has started.
The safest bet is to enter new positions within $15 100 - $15 400 range. This would allow for appropriate risk/reward ratios.
