The LTC/BTC ratio has meandered within a pretty well defined sideways channel for almost a year now, kinda between .01 and .02 with a little leeway on either side. Coming up in about 2 weeks there is a convergence of trends, we'll see what happens but it is reasonable to expect it to stay within the sideways channel for at least the short-medium term. Trades between 0.016 and .019 have been good. Check out www.reddit.com/r/LitecoinTraders for discussion/analysis from traders more experienced that myself :P
