Veteran Chan Theory traders pour their order-book experience into the product, so every AI annotation fits real trading conditions.
“The gap between retail investors and institutions was never about intelligence, but about tools — and the tools are already in your hands.
Our philosophy
Reinventing traditional technical analysis,
A fair starting point for retail investors
Reading the market used to be a privilege of institutions — expensive terminals, lagging indicators, and charting skills that took years to master. TodayChart hands all of that to Chan Theory AI: a brand-new technical analysis perspective that reads the market in seconds and gives you only the conclusion.
Traditional technical analysis
THE OLD WAY
- Indicators lag — by the time a signal appears, the move is over.
- Subjective charting — ten people draw ten different trends.
- Information overload — news and indicators pile up into a mess.
- Institutions enjoy every advantage in tools and speed, while retail investors are left to take the hits.
TodayChart Chan Theory AI
THE CHAN AI WAY
- Chan Theory AI reads the market in seconds, generating structures and buy/sell points in real time.
- AI automatically marks fractals, strokes and pivots — no more subjective charting.
- No news dumps — AI highlights give you the core takeaway directly.
- Built for retail investors, so ordinary people can beat Wall Street too.
What is Chan Theory
Chan Theory (Chan Zhong Shuo Chan)
Remarkably precise · Anticipating bull and bear turning points
Chan Theory was systematically introduced by an author under the pen name “Chan Zhong Shuo Chan”. It describes the market through geometric structure rather than lagging indicators — fractals → strokes → segments → pivots → trend types — progressively breaking any move down into structures that can be identified and reasoned about.
What makes it truly remarkable is its almost uncanny precision: it pinpointed major bull-market bottoms amid peak fear in both A-shares and U.S. stocks, then warned of major tops at the height of market euphoria—turning bottom-fishing and timely exits into a repeatable discipline.
For over twenty years, Chan Theory has been one of the most widely followed and repeatedly validated technical frameworks in Chinese trading communities. TodayChart brings this remarkable framework to AI, making elite-level precision accessible to everyone.
