COMPARISON

While25 vs NinjaTrader, for traders who would rather write Python.

NinjaTrader is a serious futures platform, and NinjaScript lets you build real indicators and strategies, in C#, inside their framework, on Windows. While25 asks a different question: what if the platform carried a plain Python workspace instead, and the broker was your choice rather than the house?
