Other times the new uptrend is established by new reaction highs or a break above resistance . Ideally, the advance is fairly orderly and lengthy with a series of rising peaks and troughs that may form a price channel . Less erratic advances are satisfactory, but run the risk of forming a different pattern. As a consolidation, there could be a continuation pattern such as a rectangle or ascending triangle . Generally speaking, the bigger the advance, the bigger the correction.
Some technicians like to measure by points, others in percentage terms.
The decision of which method to use will depend on the individual security and your analysis style. However, if there is no readily identifiable pattern, then some other continuation breakout signal must be sought. In this case, much will depend on your trading style, objectives, risk tolerance and time horizon. Another method might be to wait for a break above the reaction high set by the first advance as confirmation of continuation. This method would make for a late entry, but the pattern would be confirmed.
