StockCompass Trading Discipline Engine

Turns a retail trader's written rules into a daily scan-generated buy/sell list and keeps them honest.

Problem

Many retail traders buy and sell on the mood of the day, never look back at the rules they wrote down, and cannot tell after the fact which trades followed the plan and which did not. Broker apps and quote tools only help you place orders; they don't enforce discipline.

Solution

Users visually compose their own conditions (RSI, moving averages, volume ratio, PE, etc.), the system scans a stock pool after market close and lists buy/sell signals, backtests on historical daily bars, and tags every real trade as 'followed the rules' or 'didn't'. No broker connection, no money handling, no stock recommendations.

Users

Retail traders with written rules but weak execution, covering A-shares, HK and US markets.

MVP

Visual condition builder (5-8 common indicators); post-close scan of a stock pool with a signal list; historical backtest including earnings dates; trade journal with a two-pile 'followed/didn't follow' review; email or push alerts (can be Pro).

Revenue

Free tier limits the pool to 50 tickers, basic signals and journal; Pro subscription unlocks backtesting, email alerts and a larger pool.

Why now

LLMs and free daily data like Yahoo Finance let a solo developer ship usable signal and backtest logic cheaply; willingness to pay for discipline rises when markets are volatile.
