FAQs

To help you finally understand the topic, we have answered the frequently asked questions of beginner traders.

Is option trading suitable for beginners?

Primary markets vs. Secondary markets

If you’re new, you might be wondering whether or not the Sell to Open vs. Sell to Close put option is a good idea to start trading. The answer to that question depends on a few factors, including your level of experience with financial markets and your investment goals.

If you’re a complete beginner, then it’s probably not a good idea to start trading options right away. They are complex financial instruments and can be difficult to understand and trade successfully. If you’re just starting out, it would be better to first learn about the basics of investing in the stock market before trying to trade options.

On the other hand, if you already have some experience with financial markets and are looking for a way to potentially earn more, then it could be a good idea. Options offer the potential for higher returns than simply buying and holding stocks, but they also come with more risk. So, if you’re experienced and comfortable with taking on more risk, then trading options might be good for you.

Can I lose buying a call?

When buying a call, the breakeven price is the call’s strike price plus the one paid for it, i.e., the premium. For instance, if a $25-strike call is trading at $2.00 when the asset price is at $20, the security would have to rise above $27.00 before it expires to break even. Otherwise, the trader will lose up to $2.00 paid for the contract.

The bottom line

Now that you understand what Sell to Open is vs. Sell to Close, it’s time to put that knowledge into practice. If you’re looking to enter a new position, use the first option. And if you want to get out of an existing position, be sure to use the second. Choosing the wrong order type could cost you dearly, so it’s important to be aware of the distinction.
