USD/SGD huge resistance zone

Went short yesterday and added to my position. The currency has now gone below the 200 and 50 moving average on the 15 minute chart. This IS a BIG zone and right now the Risk to Rewards is nearly 2x reward. Initial take profit area is at .382 fibbonnaci at 1.373 but overall I am looking for near 50% retracement at 1.3630. With potential double top, I see this as higher probability trade on the daily and weekly timeframe.
