hi，I am Jinjin

I like this quote from Charlie Munger: “The soul of investing has two parts: 1. Understanding the magic of compound interest. 2. The ability to earn compound interest.”

## ◉

*Compound Interest Calculation*

Based on the user’s input of initial investment amount, interest rate, investment period, and compound interest calculation frequency, accurately calculate the final asset value under compound interest. Whether you want to calculate annually, monthly, daily interest rates, or statistics based on yearly, monthly, daily cycles, all your needs can be met, allowing you to better understand investment returns.

## ◉

*Trade Profit Calculation*

After entering information such as buy-in (opening) and sell-out (closing) prices, trade quantity, etc., calculate the profit or loss amount of the trade, helping users evaluate the trading outcome.

## ◉

*Target Price Calculation*

Based on the user’s set expected return rate and the current price, calculate the target price required to achieve the target profit, assisting users in formulating trading strategies.

## ◉

*Trade Quantity Calculation*

Combining the user’s capital size, risk tolerance, and trading plan, intelligently calculate the appropriate trade quantity, helping users control risk and optimize fund management.
