Looking at GBPUSD for the next bearish run on the higher time frame.
Here on the intraday chart, after price dropped down from the top, we see a period of consolidation of price.
Few structure were formed to correct the overall down move, and latest price shows us some good reversal price action.
We see a recent double tops, and a reversal structure on the LTF to push the price down, good indication this can be the start of the next bearish move.
To be more safe, I would want to see price break of of this current channel like structure, and form continuation correction to get in the sell.
