A portfolio web app that measures the risk of your real holdings, rebalances them with Markowitz mean-variance optimisation, and reads candlestick chart screenshots with OpenCV.
Chart Vision benchmark: synthetic charts with known prices, 13 styles, incl. JPEG and resize
Built on a foundation of quantitative mathematics and deep learning neural networks.
Measures your real holdings on two years of daily prices: volatility, worst likely daily loss (95% VaR), biggest drawdown and which holding carries the most risk.
Automatically rebalance your portfolio using the Markowitz Efficient Frontier to minimize volatility while maximizing risk-adjusted returns.
Pick Conservative, Moderate or Aggressive, add any new money you plan to invest, and export a PDF plan with exact buy/sell amounts and plain-language suggestions.
Upload a candlestick screenshot and OpenCV reads every candle, turning the image back into open, high, low and close prices.
Markowitz mean-variance optimisation with an interactive efficient frontier: pick your assets and see the minimum-risk and maximum-Sharpe mixes.
How data moves through RAPOS.
Your holdings are stored per user in Supabase (Postgres with row-level security).
The FastAPI backend pulls real daily prices and computes returns, volatility, drawdown and correlations.
Mean-variance optimisation finds minimum-risk and maximum-Sharpe weights.
Compare current and target weights and see the trades needed. RAPOS never places orders.
