In 30 minutes chart, the pair has created a lower high point. Price retested 1.2530 then moving downwards, running below 200 MA and heading to potential reversal point 1.2490.
There is a potential bullish gartley pattern with D point at 1.2490. So price is now may forming the CD leg of the chart.
But I won't choose to take long position immediately once price hit the level, instead, I’m going to find confirmation signals then decide to buy or sell.
As a trade in short time frame, I won't choose to hold it for too long, in order to improve the turnover and efficiency of the money.
Pay attention to the president Trump's speech on Thursday. Wordings relate with giving pressure to Iran may trigger the tension and improve the oil price, which may in turn help the pair moving further lower.
