Comparing to the ETH, starting the down-turn on 1/17 they have traded virtually identically. After the breakout of triangle, the stoch hit low before the market of ETH went up to break above the last bounce on the top of the past triangle.
If the same follows for LTC it should see passing above $215.
It may not be the best reason to make a trade, but BTC led the market in 2017. If ETH is leading it in 2018, maybe LTC won't be far to follow for some profit in the short-term.
