Manifold-BT
Fast backtesting for Python traders, powered by Rust
What it does
A backtest tells you how a trading strategy would have performed on past data. It is the core of quantitative research. Manifold-BT runs 500,000 of them in a few seconds, on a Rust engine with a Python API. It also ships an MCP server, so Claude or Cursor can run the tests directly and answer with real numbers instead of a plausible guess. Ask in plain English, get measured results.
Python backtesting library powered by Rust: realistic execution, sub-second backtests, and large parameter sweeps for systematic trading research.
Rust core, Python API. Realistic execution modeling, sub-second performance, reproducible research workflows. import manifoldbt as bt from manifoldbt.indicators import close, sma, rsi fast = sma(close, 20 ) slow = sma(close, 50 ) signal = bt.when((fast > slow) & (rsi(close, 14 ) < 70 ), 1.0 , 0.0 ) strategy = ( bt.Strategy.create( "momentum" ) .signal( "signal" , signal) .size(signal * 0.25 ) .stop_loss( pct = 3.0 ) .take_profit( pct = 8.0 ) ) result = bt.run(strategy, config, store) print (result.summary()) Same strategy, same data, real-time race manifoldbt ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ██████████████████████████████ raptorbt ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░…from manifoldbt.com

- IBI built a tool to find trading signals that aren't just random luckSep 2025 · hikaro.app · ▲9
Hi HN, I'm a solo dev and for the last few months I've been building Hikaro, a tool to find statistically significant trading signals for [e.g., US equities, crypto, forex]. I built this to solve my own problem: I was tired of backtests that looked great on paper but failed in practice. Simple metrics like "win rate" can be misleading, so I wanted a way to quickly tell if a signal's performance was genuine or just noise. Hikaro ingests daily market data and runs statistical analysis on various trading signals. The goal is to surface signals with strong properties, like: Low p-value: Evidence…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
