Under 1,495 -1,50 sell rallies towards 1,4325. Mind the last weekly low around 1,455. On the monthly chart the cable broke a 61,8 Fibonacci support line around 1,495. Although the 200 SMA remains rather flat, shorter terms SMAs are pointing down. This is why under 1,50 I prefer to sell rallies into resistances, to try and reach the 78,6 Fibonacci resistance at 1,4325. 
On the weekly chart shows we broke a support near 1,52, which is a 23,6 Fibonacci support line. GBP/USD also broke down a minor weekly support around 1,485, and any rally into that level should be checked for selling signals. A note of caution will be the last weekly low at 1,4568. It may prove tough to break down. 
Finally the daily chart : the cable just broke an ugly bearish channel. Any retest of that channel support is a good place to look for short signals.
