Trend is bullish in four hours chart. Key support level is present at 0.6544 price level. In past few trading days, price has printed a possible Double Zig Zag pattern. Currently; price is falling down and may be a top is in place. However; the trend is still up. A good idea is to look for a buy trading chance to join an up trend. However; if bearish candlestick closes below 0.6544 vital support level then up trend is going to end. In this case, I would prefer to stay out of the market and re-analyze the price action.
