BigQuant

What people say

BigQuant (formally Kuang Bang Technology, founded 2016 in Chengdu by Liang Ju) sits alongside JoinQuant and MiQuant as one of the three platforms Chinese quant hobbyists compare first, per recurring Zhihu comparison threads. Free registration gets you the core research environment -- over 2,000 built-in factors, a factor-expression engine for building derivatives, backtesting, and paper trading -- with a PLUS membership layered on top for courses, a 10,000-plus-article knowledge base, community access and priority compute for GPU-heavy factor mining or deep-learning strategies. Exact PLUS pricing isn't published; it runs through a recharge/credits system rather than a public price list.

The recurring complaint across user threads is that BigQuant has no brokerage license of its own, so "live trading" means routing orders through a separate connected broker -- described by one Zhihu commenter as the platform's biggest sticking point (最大的槽点) for anyone expecting an end-to-end pipeline. A second complaint cluster targets the AI assistant: users report it doesn't reliably know current API syntax and produces strategy code that fails to run once a strategy gets past boilerplate, calling repeated back-and-forth with it a waste of time. A third is that BigQuant markets itself as usable with "zero code," but real strategy work still demands solid programming skills, and documentation is described as hard to search.

On the plus side, nobody disputes the data depth or the factor library size, and the platform has enough of an install base to run its own open GitHub toolbox (BigQuant/bigquant, still in early active development with a handful of commits) alongside the hosted product. For readers in ASEAN markets, the practical limit is coverage: the platform, its documentation and its community are built around China's A-share market, with no indication of Southeast Asian exchange data or English-language support -- and no evidence the platform has ever been localized for a non-Chinese audience, in contrast to some rival quant platforms that at least offer partial English documentation.
