Planar.jl is a Julia framework for building custom trading bots that supports backtesting, paper trading, and live trading through a unified interface. Its standout feature is 'by-simulation', which runs the backtesting simulator alongside live trading to detect exchange misbehavior, alongside strong support for margined positions, large datasets via Zarr, and lookahead-bias-aware time handling.

Target audience: quantitative traders and backend developers building algorithmic trading systems
