AUD/USD showed a smooth fall of the price yesterday, but the move was on small volume, so we can't consider it as a reversal signal. But on the other hand, we can open long positions only after a strong and sharp breakout of the resistance level 0.7893. The move should be supported by large volume. A potential of the deal is 70 pips.If the price continues falling on small volume, we should stay out of the market.
The bottom line: long positions after a breakout of the resistance.
