It helped complete a topping pattern that we had been tracking. Sterling had recovered smartly since dipping below $1.20 in mid-January.  The rally stalled in front of $1.3055, which is the 38.2% retracement of the losses suffered since the UK referendum a year ago.  More recently, it has appreciated this month ahead of election. It reached the high while the British people were going to the polls on June 8 near $1.2980.  

Sterling carved a potential head and shoulders topping pattern. The left shoulder was shaped in the first half of May and topped before reaching $1.30. The head was the push in the second half of May to almost $1.3050.  The right shoulder was formed in the past two weeks.  The neck line appears to be around $1.2760. The measuring objective is in the $1.2450 area. On Bloomberg, which has the October low of $1.1840 (other services record a lower low), the 50% retracement of the rally since is $1.2445.  

From another perspective, sterling initially held the 38.2% retracement of this year's rally. That retracement is found near $1.2640.  The 50% retracement is about $1.2520 and the 61.8% retracement a little below $1.24. The RSI and MACDs favor additional losses, while the Slow Stochastics are lagging.  Of course, such a dramatic move has pushed sterling well below its lower Bollinger Band (~$1.2775), which is where its bounce after the low was recorded stalled. It should offer initial resistance. The high since the first exit poll-inspired drop was almost $1.2830.
