GBPUSD (CABLE) ANALYSIS

 Good evening traders, I hope you're doing well and ready to tackle the markets this week as last week was more favorable for me in crypto markets than in currency markets. Looking into the charts today, GBPUSD price dropped to a key H4 and daily chart demand zone at 1.17650 & 1.18290 which is the origin of the previous rally to the supply zone at 1.22843 & 1.23781. Price has filled the range from the demand zone to supply and back to demand. Price dropped into demand, formed strong wick rejections on H4, candle close inside demand followed by a rally in form of a strong bullish engulfing candle on H4 to 1.18785 and closing above demand.
Price then dropped back into demand at 1.17650, formed rejection wick and candle close inside demand on H4 followed by a rally out of demand in form of a bullish engulfing candle on H1 showing the zone has held and the bullish bias is still valid until demand breaks. 
Took buy entries during NY session at 1.17881 with SL at 1.17520. Setup taken is a drop base rally, a reversal setup.
