Renko Chart
A chart of bricks that print only after price has moved a fixed amount, so time is ignored.
Teaching sketch. It shows the shape, not a live quote and not a trade signal.
Definition
Renko bricks are equal in size. A new brick prints only when price travels the brick size from the prior brick. Time can pass with no new brick. Reversal bricks often need two brick-sizes of movement, depending on the platform.
How it works
The brick size can be a fixed price, a percent, or a multiple of ATR. A larger brick filters more noise and lags more. Wicks are usually not drawn, so the path is the closes that crossed each threshold.
How to identify it
Equal rectangles stacked diagonally, not aligned to a clock. Empty stretches of the session simply do not appear.
Bullish reading
A run of rising bricks is an upswing that kept making the brick size. A reversal brick down is the first sign the swing paused, not proof of a new trend.
Bearish reading
A run of falling bricks is a downswing of the same logic. One up brick after a long decline is a pause until more up bricks follow.
How traders use it
Renko is used to see swings without every five-minute flicker. Entries are still executed on a time-based chart, because a brick can finish long after the price that created it.
Common mistakes
Choosing a tiny brick so the chart looks like a normal candle chart, then wondering why it whipsaws. The brick size is the whole indicator.
Limitations
Renko hides time and usually hides the high and low inside the brick. A violent wick that returns inside the brick size may never print.
This note explains the term. A sketch shows the shape of the idea. Neither is a recommendation, a signal, or a comment on any security. Indicator settings and exchange conventions differ. Check the live chart and the contract specification before you use a number.
