GBP/USD potential bearish flag

The GBP/USD pair formed a nice double top around 1 month ago starting a down trend. If the bearish flat pattern meets all criteria for a sell it would also sit nicely with the 0.618 fib level from the top of the double top and a key support resistance level at around 1.2415. This week has got a lot of USD fundamental news finishing the week with NFP's so hopewell will have some nice volatility. I know the majority of traders will be trading GBP long so this is against most peoples views, please give any comments/feedback - thanks
