I'll make a speculative call right now - Big money sell off to drive down price. Tomorrow LTC leads the rally to rebound prior to block 1371111. All chart signals indicated an uptrend. My guess this will show as an aberration on the 1D, and it will resume the course we were on today. Just a blind speculation from an outsider. It was also a good time to take profits, as indicated by red rectangle. The top of the previous downtrend - existing resistance line.
