Options

Selling calls against shares, selling puts to buy them, and reading the volatility priced into a contract, with every premium sum worked through.

Most option strategies for stock traders start from shares you already own or would be happy to own. A covered call trades away some upside for income, and the wheel puts a cash-secured put in front of it. Both look simple on the order ticket. Both also carry the full downside of the stock, which the premium does not cover.

The covered call calculator shows the maximum profit, the breakeven and the upside you give up at any strike and premium.

Then there is buying. A call or a put bought outright can lose its whole premium, and the price of that premium depends heavily on implied volatility, so the pages on delta, implied against historical volatility and the crush after earnings explain what you are paying for before you pay it. Size any option trade by the most it can lose, which for a bought contract is the premium and for a sold one can be far more.
