During the Chinese New Year holiday, I finish my first useful Android APP - Stock Price Calculator.
Introduce of Stock Price Calculator
The band calculator of stock price is to make clear the bottom price and selling price of the stock on that day. Enter the stock price, and the price corresponding to each fluctuation point will be calculated automatically. Up and down 10%.
At least, it’s useful to me :)
