As of yesterday, ARB has fallen through a strong area of support which held the bull trend going for over a month. In my view, there's a high possibility that ARB will continue to fall, potentially even retesting the June lows around 0.92
ARB is quite oversold at the moment, so we're going to anticipate a bullish correction towards 1.19 or so. Stop just above 1.21 for an optimal risk-reward ratio. A more risk-averse trade would be to take (partial) profits around 1$.
