What is a Renko Chart
Renko is a chart type, developed by the Japan. The concept of Renko came from Brick in Japanese, which gets constructed on price movement. The chart looks like a series of bricks, look below. Renko brick can be of different fixed sizes, depends on trader’s need. A new brick is created when the price moves up or down to that brick size price amount. Each block is positioned at a 45-degree angle (up or down) to the prior brick. An up brick (Uptrend) is typically colored green, and a down brick (Downtrend) is typically colored black or red.
Brick Size: In renko chart there is always a fixed brick size. in candlestick, the candle size varies based on price movement, but in Renko, the brick size doesn’t vary, it is predefined and fixed, if price moves one direction in multiple of brick size, then bultiple brick shall form.

How to read a Renko chart
Renko chart helps trader to eliminate noise or sideways movement of any Script, as the brick gets built only if the price moves up or down by the Brick size fro the top or bottom of the last brick. Is this sounding confusing, let me explain in further detail from the above image.
In the image above, the last closed price of BANKNIFTY Future is Rs. 27,724 and the Brick size is Rs. 4. There can be two chances for the next brick formation. 1st, the next brick can be a up Green brick or down Red brick. To create an up brick, the price have to move up to Rs. 27,728 (i.e. 4 Rs up from last closed price) or to create a Red down brick, the price need to move down to Rs. 27,716 (Rs 8 down from last bricks closed price, as last brick is a Green brick).
Please do remember to get a new brick formation in the chart price need to move Rs 4 up from last bricks closed price (in case last brick is Green brick) or Rs 8 up from last bricks closed price (if last brick is red brick) and visa versa for Red brick formation.

Drawback of Renko chart
There is no drawback of Renko chart, only restriction is we can’t really plot any indicator with RENKO. Renko is a self sufficient chart cum signal generator, each brick of a Renko chart gives market direction for a script. As Renko chart is independent of time, hence if we plot any indicator along with Renko then that will give us erroneous result.
