The Random Walk indicator is used to determine if an issue is trending or in a random trading range. It attempts to do this by first determining an issue's trading range. The next step is to calculate a series of RWI indexes for the maximum look-back period. The largest index move in relation to a random walk is used as today's index. An issue is trending higher if the RWI of highs is greater I'm looking for the Random Walk Index for MT4. The original formula developed by Mike Poulos used 4 indicators- a short-term period of 1 to 8 bars of the highs and lows, and a long-term indicator of 8 to 64 bars of the highs and lows. Researchers who work with perturbations of random walks, or with particle systems and other models that use random walks as a basic ingredient, often need more precise information on random walk behavior than that provided by the central limit theorems. In particular, it is important to forecasts of the random walk model look similar to those of the mean model, except that they are always “re-anchored” on the last observed value rather than the mean.of the historical data. For the random-walk-with-drift model, the k-step-ahead forecast from period n is: n+k n Y = Y + kdˆ ˆ where
