Platinum Reversal From Previous Resistance

TVC:PLATINUM   CFDs on Platinum (US$ / OZ)
Last night I took a short trade on platinum which reversed at 875. This is a resistance level from 25th June and 6th November last year. It also coincides with what looks like the top of a price channel . Unless it bounces at 850, I can see a see an initial target of 830 where I would expect some fairly strong resistance but with a final target around 800.
