Price at Critical Support Level

FX:GBPUSD   British Pound / U.S. Dollar
Price has reached the completion point of the large ABCD
pattern starting in July. This is also the lower band of a
Pitchfork as well as the 76,4 fib of the july -13 july-14 bullwave.
This may call for caution to short right from this level. But if it
breaks and hold, the next significant support stands between
1,48-1,50 / previous low and Yearly S1.
