The Three Drives pattern was originally outlined by Robert Prechter. It is not used often in trading, because it is rare to spot and far less common than other harmonic patterns. It consists of symmetrical price movements with identical Fibonacci
projections in a 5-wave structure. The Three Drives pattern is defined by three distinct, consecutive and symmetrical drives to a top or bottom where each drive completes at 1.13, 1.27 or 1.618. Symmetry in both price and time is critical. It is important not to force the pattern on the chart. If it is not really there, the best decision would be not to trade it.
A reversal is likely to happen at the completion of the third drive. Conservative traders look for additional confirmation that price is reversing. Targets can be set at the discretion of the trader but normally extend beyond the last retracement. If the pattern fails, this could point to a strong continuation in the previously dominant direction. The Three Drives pattern can be either bullish or bearish.
