Should we be looking for another sell on GBPUSD or what?

You must put into consideration of the volatility and uncertainty when trading GBP pairs. Much of this has to do Brexit negotiation. so the little bullish move we are seeing might be a retest of structure or it could be the market is going to breakout. whatever your decision is always put equity management in mind and a good R/R ratio. personally for me, it will be another sell if price approaches the blue structure
