Bearish divergence, possible break out of rising wedge on GBPUSD

On the 4h chart of Cable, a bearish divergence (in RSI, MACD, and Stochastic) is observed with no higher-highs being formed, signaling weakness in the current bull trend. A break out of the rising wedge and a subsequent break below the local support of 1.32990 could provide a short signal where it is expected to fall to at least the 4H support of 1.31760. However, I believe it could drop further to longer-term support at around 1.30700 and possibly even further to 1.28800. If price does not break the first support level at 1.32990, the trade is not taken.
