Tuesday was a trading range day. The Emini is trying to be neutral going into the Brexit vote on Thursday. Hence, tomorrow will also likely have a lot of trading range price action. Logic favors the UK staying in the EU, but there is a chance that emotion and stupidity will win. There is a 50% chance of a sharp move up or down, regardless of the vote.
