not sure what the odds of a bullish reversal are here, but it doesn't really matter. here's how i plan on playing this with minimal risk:
(1) if price finds support and bounces off the trendline, i'm buying. this would appear bullish to me because (a) it would form an inverse head & shoulders pattern, and (b) this is our long term bull trendline. stop tightly below the trendline/shoulder line.
(2) at the top of the triangle, take a partial profit to hedge against a rejection. AND/OR wait for a rejection and sell for small profit.
worst case here is that the price never makes it to the top of the triangle, and you can either manually bail/break even, or hit the stop immediately below the trendline for a minimal loss (like 2%).
best case is a full on bullish reversal, and you can tell all your friends you're a genius for buying the dip. i do still expect a retest of that down trendline at some point.
