Overview of Renko
Renko chart is thought to have acquired its name from the Japanese word for brick, "renga". In Renko charts, a box (or "brick" as they're called) is drawn in the direction of the prior move only if prices move by a minimum amount (i.e., the box size). The bricks are always equal in size.  The box size is specified by the user, and can be any value greater than or equal to the tick increment of the symbol being charted (minimum of 0.25 for ES).  Similar to Range Bars or Point & Figure charts, the frequency of Renko Bars is driven by price movement, not by time.

Basic trend reversals are signaled with the emergence of a red or green box/brick. A new green brick indicates the beginning of a new uptrend. A new red brick indicates the beginning of a new downtrend. Since the Renko chart is a trend following technique, there are times when Renko charts produce whipsaws, giving signals near the end of short-lived trends. However, the expectation with a trend following technique is that it allows you to ride the major portion of significant trends.

Renko charts can also be very helpful when determining support and resistance levels since they isolates the underlying price trend by filtering out minor price changes.  Renko charts are also very effective at identifying key support or resistance levels.

Renko Charting in Investor/RT
Renko is now supported in traditional charts as a periodicity (and a drawing style). This significant enhancement marries the powerful features of the traditional chart window (indicators, buttons, multi-panes, etc) with this unique charting style.

To change any existing chart to a Renko chart, simply double-click on the instrument (bars or candles) in an existing chart, and setup the chart with a Style of "Wickless Candles".  Wickless Candles will result in the traditional Renko "boxed" look and feel.  It will simply chart a box from open to close.  These boxes are often referred to as "bricks".  Users may opt for the "Candlestick" style, which will not only give the open/close box, but provides additional information with the candle wicks representing the high and low of each bar.

The Periodicity Control now has a new option of "Renko" just below the "Point and Figure" choice.  Select this option, then provide a box size in the space provided below.  The box size can range from the tick increment of the instrument (0.25 for ES) to multiples of the tick increment (0.5, 1, 2, etc).

In order to force each Renko box to be drawn perfectly square (the height of each box equals the width), a new vertical scale option has been added.  Double-click in the vertical scale to bring up the vertical scale preferences.  Select the 3rd Scaling Method specifying "Automatic scaling with Square boxes".

This option will keep the boxes square regardless of changes in chart dimensions, scrolling, or zooming.  Some user may continue to prefer the Automatic scaling method, which tends to make better use of the vertical space in a chart.  Once you've setup your scaling as "Square Boxes", you can easily toggle to automatic by clicking the "RA" until it becomes an "A", and toggle back to square boxes by again clicking on the "A" until it turns back into an "RA".

Investor/RT can be configure so that Renko bars reset at the beginning of each session (fresh start), or continue across session boundaries.  The fresh start option is generally used for symbols that might gap heavily between session (and result in a long sequence of boxes to fill the gap).  On symbols like ES that trade around the clock, the fresh start option is generally not needed or preferred.  Go to "Setup: Preferences: Charts: General".  If the "Continuous Tick & Volume Bars" checkbox is UNchecked, Renko charts will operate in "fresh start" mode.  If it is unchecked, Renko charts will operate in "carry over" mode.

Tokens have been added to RTL to support Renko.  Scans, signals, and custom indicators operating with Renko periodic data can use these token to inspect the state and box size of the Renko boxes.  To test the state of the PNF box use the RENKO_STATE token. Constants RENKO_UP and RENKO_DOWN were added to enable expressions such as "RENKO_STATE = RENKO_UP" or "RENKO_STATE = RENKO_DOWN". The RENKO_BOX token gives you the box size of the Renko data.

As an example, the following signal would look for 3 consecutive up boxes followed by a down box:
