GBPUSD - Price has reached a top

Recently the pair has reached 1.3170 which represents the third summit of a bearish trend line weekly.
The resistance seems strong and I also noticed a strong reaction of the price on this level. Considering all of this, I reasonably thinks that a bearish trend is taking place. A stop loss above 1.3170 will prevent from a bullish continuation.
1.2800 is a good first target for this opportunity.
