      For example, when institutions such as Goldman Sachs, Men-ill Lynch,Fidelity, and Berkshire Hathaway initiate large-volume buy and sellprograms in individual stocks, intraday price trends will reveal themselvesin price/time charts. In some cases, more than one institution willinitiate the same directional program in a given equity. When this happens,movements will be more dramatic and will usually be confirmed by anabnormal volume breakout. However, when institutions initiate opposingdirectional programs, whipsawing price patterns will reveal themselves,confirmed by abnormal volume patterns. If institutional buying and sellingpatterns were the only variable to be considered, intraday price movementswould be more consistent, and technical indicators could be used to moreeffectively predict intraday price movement. However, other variablesstrongly influence price movement on an intraday basis, making technicalanalysis ineffective in many cases.
