Redfin $RDFN has made a dramatic recovery in 2019 against a bearish trend in 2018. However, there is a significant pullback at the moment that will be challenging the price bottom that was formed at the end of 2018.RDFN Daily Chart(click to enlarge)Bullish Reversal and Pullback:- As we can see on the daily chart, price has broken above a falling trendline resistance and the cluster of moving averages in March. - it has since extended the breakout but has pulled back in the second half of April.- With price falling below a rising trendline and below the $20 mark, we are looking at a strong pullback that is likely going to challenge the double bottom we saw develop at the end of 2018.Key Support:- There is a bunch of support factors in the $17.80-$19.20 area. - I would expect some choppiness here, but ultimately I expect price to show support here if RDFN is going to be bullish.- Maybe there will be a period of consolidation (sideways action), but if price can hold above $18 for example and eventually rebound back above $20, I would be convinced that the price bottom has been set and that RDFN has the $26 resistance pivot in sight.
