USD/RUB Short on Technical Analysis

I know, it has been only three days since I have closed my USD/RUB buy, but I have just went short on USD/RUB based on some pretty evident technical analysis factors. The currency pair is consolidating inside the ascending triangle on the weekly chart. During two previous instances of USD/RUB hitting the upper resistance (January and August), the pair retreated back to the lower trendline. I expect the same retracement this time too:

I have used a market order to execute the trade and have got in at 71.1087 rubles per dollar. I have a hard stop-loss at 72.05 and a hard take-profit at 67.12 but I will also consider exiting by timeout (if the currency rate leaves the ascending triangle) or by a trailing stop-loss. Also, the position size I use here is a good deal lower than I usually use on my USD/RUB trades.
PS: I know, the trade might look like a suicide considering the recent trend in oil and the overall situation in the Russian economy, but it is a technical analysis setup that should be over in a few weeks, not a long-termbuy-and-hold type position.
Update 2015-12-30: The trade hit a stop-loss on December 28 at 9:51 GMT as the currency pair broke through the upper border of the triangle:
