Waiting for a break of support level

The strong resistance level 148.100 has proved to hold price very well since the end of last year. Price failed to make a higher high recently with a strong bearish reaction at the support zone. We have just seen a retracement to 146.800 and rejected twice showing that price did not idle at this level.I am now waiting for price to react at support level 145.000 to then decide if I will enter the short position.
