The story of AmiBroker 6.35 is defined by a massive leap in speed, particularly for traders managing large amounts of data. Released in late 2019, version 6.35 was marketed as a "performance beast" that solved one of the most frustrating bottlenecks in quantitative trading: the time it takes to process and display millions of rows of data. The Speed Revolution
Before version 6.35, "Explorations"—which traders use to scan thousands of stocks for specific setups—could take nearly 40 seconds for complex datasets. The developer, Tomasz Janeczko, discovered that the bottleneck wasn't the calculation itself, but how Windows handled displaying millions of cells in a list.
20x to 40x Speed Gains: By writing a custom formatting function that bypassed standard Windows list-view limitations, 6.35 reduced those 37-second explorations to just 1.8 seconds.
Massive Output Handling: Benchmark tests on 20 years of Dow Jones data (producing 56 million cells) showed the 64-bit version was 38 times faster than the previous version.
Flicker-Free UI: Version 6.35 introduced a workaround for the "terrible flicker" that plagued traders when scrolling through massive amounts of real-time data. The "Dark Side" of Trading
One of the most visually significant changes in 6.35 was the official introduction of a Dark Theme for all list views.
Traders could finally switch to a "black theme" for the Analysis and RT Quote windows, a feature highly requested by those spending long hours in front of monitors.
It brought a level of visual consistency, ensuring that red/green (up/down) color values were exactly the same across different windows for better pattern recognition. Key Technical Upgrades
Beyond speed and looks, 6.35 added several "under the hood" tools for serious developers:
SafeDivide Function: Added a new SafeDivide(x, y, valueifzerodiv) function to prevent "division by zero" errors from crashing complex backtests.
Function Navigation: The AFL Editor added a new combo box that automatically detected user-defined functions, allowing for quick navigation in scripts that were thousands of lines long.
Improved Batching: It introduced clipboard support (Copy/Paste) for batch items, making it much easier to move complex sequences of automated tasks between different workspaces. Why It Matters
AmiBroker 6.35 solidified the platform's reputation as one of the fastest backtesting engines in the world. While modern tools like Python or TradingView are popular for their ease of use, version 6.35 reminded the community why professional "quants" stay with AmiBroker: it can run a million-bar backtest in seconds.
