The instrument is sitting in the upper range of the corridor but its ability to re-test the tunnel's limit is questionable given several obstacles that lie on the pair's way towards this formidable resistance. The level of 1.3725/30 (daily PP, R1; four-hour R1) represents the first hindrance, while 1.3737/8 (four-hour R2; 50-hour SMA; daily R2) and 1.3743/6 (daily R3; four-hour R3) also are significant constraints for a climb.
