How do I choose the best Renko brick size?

A good approach is to test multiple brick sizes using the same strategy and evaluate return, drawdown, trade count, and profit factor. Brick size should be selected based on robustness and consistency, not just the best-looking return.

What is Return over Drawdown?

Return over Drawdown is a simple efficiency metric that compares total return to maximum drawdown. Higher values generally indicate better performance per unit of drawdown, but it should be evaluated alongside trade count and stability.

Why can large Renko brick sizes look good but still be unreliable?

Very large brick sizes can produce very few trades. That can inflate metrics like profit factor because a small number of winning trades dominate the results. Fewer trades means less statistical confidence and higher fragility.

Why does this strategy enter on the next brick close?

Using the next brick close is a conservative approach that avoids assuming perfect fills when a Renko brick forms. It reduces the chance of exaggerating performance and keeps the backtest more realistic.

Do I need Pine Script to test Renko brick sizes in TradingView?

You can do basic comparisons manually, but Pine Script makes it much easier to test systematically and keep the strategy logic consistent while changing only brick size.

Introduction

In this post, I’ll show you a repeatable way to test Renko brick size settings using TradingView and Pine Script, then compare results in Google Sheets. Choosing the “right” Renko brick size is one of the biggest challenges for Renko traders. The mistake most traders make is guessing a brick size, copying someone else’s settings, or optimizing for the best-looking equity curve.

In this video, I show a practical and repeatable process using TradingView + Pine Script to test multiple Renko brick sizes across different products. The goal isn’t to present a perfect strategy. It’s to demonstrate a testing framework you can reuse for your own ideas.

How to Choose a Renko Brick Size Using Backtesting

The easiest way to choose a Renko brick size is not by guessing. It’s by testing one strategy across multiple brick sizes and watching how the performance changes. When you do this systematically, patterns start to appear and you’ll usually find a brick size range that produces more stable results.

In this experiment, I used TradingView and Pine Script to keep the strategy logic consistent, then changed only one variable: Renko brick size. For each brick size, I recorded key metrics like total profit, maximum drawdown, number of trades, and profit factor. That gives you a clearer picture of whether results are driven by repeatable behavior or just a small number of lucky trades.

The goal isn’t to find one “perfect” setting that looks amazing in a backtest. The goal is to find a Renko brick size range that makes sense for your market, your strategy, and your tolerance for drawdown. This process helps you focus on consistency and reliability instead of chasing the highest return number.
