The answer is yes… We must be ready, every time the projections or extensions of impulsive or corrective waves are calculated, to make use of the cluster concept (grouped price levels) which can stop and reverse the market flow; the power of the cluster is proportional to the number of price levels. The experienced trader realises over time that the Fibonacci ratios cannot be properly applied without a strict but progressive monitoring methodology which is crucial in detecting the optimum levels of each cluster. The ratios don't have to be necessarily fixed but rather variable. When the price level corresponding to a certain ratio is broken (the market flux goes beyond the 0.50 level heading for the 0.618 level) one must assess if the next level has a higher probability of being more effective in reversing the market flow. The cluster strength is not the most important factor. If the internal structure of the ongoing wave is not complete at this level, the solid cluster won't reverse the market but it will rather cause a correction. The market flow might be stopped by the next cluster.
We can frequently notice multiple clusters whose levels can be computed ahead of time. The inexperienced trader will find it difficult to select the optimal cluster which will turn out later to be the terminal cluster responsible for stopping the market flow. They mistakenly select the closest cluster to the current level of the market. This selection is a logical process which takes into account a number of parameters. For example, it is advisable to plot a probable scenario for the development of the ongoing wave, using trend lines and applying the proportionality principle to its internal structure, a scenario which will later be confirmed or not, by the market flow.
