Fundamentally, I see Sterling is Bearish due to Brexit jitters. I believe the price action in the past few weeks have illustrated that sentiment (duh!). Monthly range have hit though hence I will set my bias for a bullish retracement bias (wait for a "confirmation candle" so I could start looking for bullish setups = entry. 1.2900 are the price that I like before I want to short it again (if there'd be a bearish engulfing/piercing candle occur on that zone)
