Dual-Currency Investment: Achieving True Quantitative Decision Support Yesterday, I made an app for automatic data extraction. Today, I’m taking it a step further and building a decision support system based on quantitative standards. Input your investment principal and risk preference, and the system uses the following data: ∙ Current price ∙ Bollinger Band upper limit (resistance level) ∙ ATM IV implied volatility data ∙ Binance Dual-Currency Investment quote list (including APY) To provide objective and rational opening suggestions: ∙ Strike price ∙ Amount of principal to invest This is so convenient—no more relying on gut feelings and random guesses. But after reviewing it, for a "balanced" risk preference, the suggested strike price is still quite conservative, and the highest APY level is only 22.4%. Seems like it needs further tweaking. The little whip is itching to get to work.
