A periodicity named Zig Zag has been added. The magnitude of the periodicity is supplied in ticks. Bar formation operates on the same principles as the Zig Zag indicator. Each bar represents a market move of at least the user specified magnitude. Each bar is an accumulation of the data of a market move. Zig Zag bars are unique in several ways. Each bar opens on one extreme and closes on the other extreme, thus there are no wicks. Also, not only does the last bar change with price movement, but the next to last bar can also change. This is the only periodicity wherein a bar other than the forming bar can change based on future price movement. The last bar is fluid and always contains an accumulation of the data during the retracement from the previous extreme. While the previous bar is always "confirmed" (it has met the users minimum change requirement), it can still change if price moves back and creates a new extreme price in that same direction before making a confirmed move in the other direction. This new periodicity is a great way of organizing bars based on market moves independent of time and should open up new analysis possibilities for Investor/RT users.
