This app will provide the number of shares you should buy based on the money you will risk between your entry point and your stop loss. Simply enter the entry price, stop loss, account size (or the max cash amount to use per ticker), the amount you want to risk, and the app will give you the number of shares to buy. If the number of shares that you could buy based on your risk exceeds the account size, this app will provide an amount based on the account size instead.
