Options Calculator
If you like options, this is such a useful tool. Let's say you want to get on the TSLA hype and buy some short term calls. You enter the ticker symbol, select the date, and the option you want to buy. It'll tell you when you start making/losing money. For this one I selected a long call that expires 10/30 and is just barely under the stock price.
As you can see, the window for you to make money is very, very small. Different options have much bigger green areas, but this tells you that if you don't hit the prices (left) by the dates (top) that are in the green you will most likely lose your money.
Options aren't bad, although they are a riskier. You just have to make a smart decision. Use this tool, click on the price/date you're shooting for and it will tell you how much you'll make if it hits by that date (obviously this is a snapshot in time, so numbers may get a little squishy if stock velocity changes)
