After a successful trade (link on the chart) we now have another opportunity in Gold . Price has broken a daily uptrend and it's now consolidating. We should keep an eye for this consolidation to be over with a sharp move below the supporting it and then sell the market. A may be formed if price moves a little higher and retrace after that.
That's a big topic.. It's all depends in structure. When we have a long term trend and we have a smaller degree correction against this trend, a breakout is all we need to enter with the direction of the trend. But when we have a possible trend reversal things are more complex. Sometimes i wait not only for the breakout of correction but for price to take out some previous swing points. Otherwise i look for a wave pattern in that correction.. I hope that helps.!
