The Spring is loaded CME:6J1!
Taking the noise out of the chart with this Renko chart - its obvious that the 'spring is loaded' - the Yen has been range bound for a week, it will make a move.
Thought this move might have more upside but based on this chart - maybe not.
RSI although not in this chart is also weakening. News, or market turmoil can change this quickly. Right now it looks like its holding on for dear life - and heading down.
