Looking at GBPUSD here for the second sell opportunities.
We see the price had a LTF pushed down from my previous analysis, but did not continue downwards, instead it correction itself up once more to the recent tops.
This is great indication from the price action that we get this reversal structure on the LTF, double tops with an ascending channel structure, good for reversal.
Now price has already push out from that correction, so any continuation this point forward would be ideal for the sell.
