The First Principles of Markets

The First Principles of Markets

Markets, at their core, operate based on a set of principles that govern their dynamics. Similarly, day trading, has its own unique principles as well. Understanding these fundamental truths can illuminate the path to success, while misconceptions can keep a trader stuck in inconsistent performance.

Let’s explore these principles:

Markets are Auctions: Financial markets function essentially as continuous auctions. This means that the price of an asset is determined by the highest price a buyer is willing to pay (the bid) and the lowest price a seller is willing to accept (the ask). The interplay of these two forces, supply and demand, sets the market price. Consider an item on eBay: the final selling price isn’t determined by the seller but by how much buyers are willing to pay.

Price Reflects All Available Information: This is the core idea of the efficient market hypothesis. It states that at any given time, the price of a security reflects all available information, including its potential for future earnings. The implication is that it’s hard to consistently outperform the market through trading or investing because the price already factors in all known information.

Risk and Reward are Inversely Correlated: Generally, the potential for higher returns comes with higher risk. This is a fundamental principle in finance that holds that the potential return rises with an increase in risk. Low levels of uncertainty (low risk) are associated with low potential returns, whereas high levels of uncertainty (high risk) are associated with high potential returns. Win-rate is a variable here as well. Sometimes a trader may opt for larger asymmetric rewards (R-factor) in lieu of a lower win-rate. Where other times traders may take a more conservative R-factor, with a higher percent chance of success.

The Principles of Day Trading

It’s essential to understand that day-trading is quite different than investing. Day traders aren’t particularly interested in the intrinsic value of the assets they trade. Instead, they aim to profit from short-term price fluctuations.

Emotion management is vital in day trading. The constant ups and downs can trigger a roller coaster of emotions, which can cloud judgment. Successful day traders tend to set strict trading rules to keep their emotions in check.

Another important principle is the role of volume in day trading. High or low volume can indicate the strength of a price movement, or the market’s acceptance of a price in a particular area. A sudden surge in a market’s volume could indicate an impending price change, or confirm a shift in market bias, which a day trader might capitalize on.

Common Misunderstandings in Day Trading

Many traders over-rely on patterns and technical analysis, mistakenly believing that these tools can predict future price movements with certainty. These tools are helpful but shouldn’t be the sole basis of trading decisions. It’s akin to predicting weather solely based on the last few days’ data, ignoring other factors like seasonal trends and atmospheric conditions.

Additionally, some day traders ignore the fundamentals of a market entirely, focusing solely on price movements. While day trading is about short-term price movements, understanding the broader context helps in making informed decisions. It isn’t about predicting the fundamentals, or attempting to capitalize on every new piece of information. However, reading the story of the market may require more than just graphical representations.
