EURJPY Sell

I am looking for a sell position in this trade because it has reached a resistance zone. At first I had predicted that I will enter the price just below the zone, but I realized that many sellers had put their stop losses just above the resistance zone. So my entry point is 141.8 and my stop loss at 142.3. My target has not changed, it will be 139.5.
The R:R is 1:4
