Here I'm seeing a Head and Shoulders pattern which has broken the "Neck-Line" and the most recent flag on the far right of the chart appears to be a "Bull Trap". The volume appears to confirm the pattern as well. Considering that there has been no major news or events regarding NEO which could possibly explain this kind of movement, I believe that the majority of the uptrend was a result of market-wide FOMO as BTC remained stable and many "ALT" / Superior tokens grew in value.
I believe that NEO will correct or complete retracement back to the 35 dollar level, consolidate around 40-42, and may continue it's uptrend in the following weeks.
Pay attention to Twitter feed's, Reddit, and be aware of any upcoming NEO events if you are looking forward to buying and selling opportunities.
Good luck.
