About this app

A Taiwan Stock Backtesting App Truly Designed for the General Public

"Enter when the moving average crosses above the golden cross," "Hold on if foreign investors keep buying"—you've heard these sayings for years, but no one ever tells you how well they've actually performed on the Taiwan stock market in the past.

To verify this yourself, you need to learn programming, buy historical data, and backtesting software is too complex, overwhelming, and you don't know how to use it, nor can you find a teacher.

To get a sip of milk, you have to build your own farm. In the end, you still rely on various rumors and stock analysts, only to get fleeced again.

This Taiwan stock manual backtesting app removes those technical barriers for you. The rules are chart cards, chosen by the user. Backtesting runs on frozen historical data. No need to write a whole program; just press a button to generate an S-F rating card.

It doesn't mention alpha, beta, Sharpe ratio, win rate factor, or equity curve; it directly quantifies things into scores that everyone can understand.

A heads-up: most rules generate D-E-F ratings. This isn't a drawback; this is precisely the app's purpose—to let you know that a theory hasn't actually performed well historically before you invest your time and effort.

【How to Use】Three steps, no programming required

01. Combine Rules: Choose 1-4 conditions from a set of rule blocks, fine-tune the parameters, and assemble the theory you want to test. It includes fundamental, technical, and market analysis; no need to learn any syntax beforehand.

02. Backtesting (Illustration): Replay this set of rules on frozen historical data to see "what it looked like overall" in the past. The app handles the dirty work of data processing, ex-dividend/rights adjustments, and delisted stocks.

03. View Rating Card: The backtesting results will be generated into a performance card: a rating from S to F, plus a three-dimensional radar of attack (annualized return), defense (maximum drawdown), and hit (win rate). After viewing it, you'll know whether that theory you've heard is worth the effort.

(Advanced: To truly turn a set of rules into a trading program, you can export it as prompts with one click and let generative AI or your own tools continue writing. Not knowing how to write programs won't affect the above three steps.)

【What It Won't Do】Said upfront to avoid misunderstandings:

× Won't tell you which stock to buy

× No buy/sell signals

× Won't help you implement strategies

× Won't connect to brokerages or handle funds
