Our testing period covers uptrend interval
(1999/02/02 2000/02/29), consolidation interval
(1999/09/01 1999/12/28), and downtrend interval
(2000/03/01 2001/02/01), which makes this model
more comprehensive in dealing with different
conditions. Fig. 1 illustrates the index fluctuation

Consolidation
What Does It Mean?
What Does Consolidation Mean?
In technical analysis, the movement of an asset's price within a well-defined pattern or barrier of trading levels. Consolidation is generally regarded as a period of indecision, which ends when the price of the asset breaks beyond the restrictive barriers. Periods of consolidation can be found in charts covering any time interval (i.e. hours, days, etc.), and these periods can last for minutes, days, months or even years. Lengthy periods of consolidation are often known as a base.
Investopedia Says
Investopedia explains Consolidation
The levels of resistance and support within the consolidation are created through the upper and lower bounds of the stock's price. Once the price of the asset breaks through the identified areas of support or resistance, volatility quickly increases and so does the opportunity for short-term traders to generate a profit.
