Don’t invest your hard-earned money on courses and signal services unless you’ve read a lot of good reviews that also point toward realistically achievable results. You should thoroughly research any program before you put money into it. You’ll notice that from posting on the forums too—many traders dump thousands of dollars into services and courses which don’t actually provide them with the means to success—and waste valuable money they could have spent on their trading accounts. By avoiding this pitfall, you can save your money and use it to build up your account. This will help you to become profitable more quickly than spending it on programs which don’t work. Good luck learning how to trade binary options!
"I'm looking for a way to definitively convince him to stop and that his edge isn't as great as it seems. I tried talking to him multiple times about the subject but I'm not as knowledgeable about the field and ultimately that becomes my shortcoming when trying to convince him why he shouldn't continue to be involved with this. Any help would certainly be appreciated."
Know the two possible outcomes. A trader of binary options should have some feel for the anticipated direction in price movement of the stock or other asset such as commodity futures or currency exchanges. Within most platforms the two choices are referred to as "put" and "call." Put is the prediction of a price decline, while call is the prediction of a price increase.
Look for a broker with a wide choice of assets and a high rate of payout. If you have a preference for a particular market check that your chosen broker offers trades on this.  Choose a broker with a demo system so that you can fully check out their platform and get comfortable with their interface before making any live trades. There are many new brokers appearing on the market every day, while they may be great brokers they will be largely unproven and will not yet have gained a reputation (good or bad). It is advised to go with the established and proven brokers who have had time to prove themselves.

First-hand information is the best information, so go straight up to forums where professional and experienced traders hand out tips for beginners. Use the opportunity to find out about the tricky parts of the market, what is recommended, what is not recommended, etc. experienced traders are a great source of knowledge, and they will let you know things that are not often mentioned in options reviews and articles.
For example, a customer may be asked to pay $50 for a binary option contract that promises a 50% return if the stock price of XYZ company is above $5 per share when the option expires.  Assuming a 50/50 chance of winning, the payout structure has been designed in such a way that the expected return on investment is actually negative, resulting in a net loss to the customer.  This is because the consequence if the option expires out of the money (approximately a 100% loss) significantly outweighs the payout if the option expires in the money (approximately a 50% gain).  In this example, an investor could expect -- on average -- to lose money.

Probably one of binary options’ most desired advantages that attract many traders is its simplicity. It has a simple premise that gives you only two (thus, the term “binary”) options and outcomes. Based on your informed guess as per various factors and patterns, you’ll choose and make a prediction on the asset’s movement if it will be true at a specific point in time. It’s a straightforward “yes or no” proposition where you’ll get a fixed percentage of your investment if you’re successful or none if you’re unsuccessful. That’s why it’s also called an asset-or-nothing option.

In the standard Black–Scholes model, one can interpret the premium of the binary option in the risk-neutral world as the expected value = probability of being in-the-money * unit, discounted to the present value. The Black–Scholes model relies on symmetry of distribution and ignores the skewness of the distribution of the asset. Market makers adjust for such skewness by, instead of using a single standard deviation for the underlying asset {\displaystyle \sigma } across all strikes, incorporating a variable one {\displaystyle \sigma (K)} where volatility depends on strike price, thus incorporating the volatility skew into account. The skew matters because it affects the binary considerably more than the regular options.
