Mastering the Two Moving Average Trading System: A Guide to Profitable Trades

As a day trader, you are constantly on the lookout for new and innovative ways to maximize your profits and minimize your losses. The moving average is a powerful tool that can help you achieve these goals. In this article, we’ll dive into the 10-21 exponential moving average trading system and how it can be used to enter and exit trades with precision.

Why the Exponential Moving Average Was Chosen

The exponential moving average (EMA) was chosen as the input for the trading system because it reacts faster to price changes than its simple moving average (SMA) counterpart. The exponential formula gives more weight to the most recent price data, which allows the average to respond quickly to new information. This makes it a more accurate indicator of current market conditions, which is essential for effective day trading.

The 10-21 Exponential Moving Average Trading System

The goal of this system is to follow momentum and make trades based on price action. It’s not designed to be used in stocks that are stuck in a trading range. Instead, it’s best used in stocks that are showing momentum in a particular direction. The 10-21 EMA trading system is based on the concept of the moving average crossover. This occurs when the 10-day EMA crosses above or below the 21-day EMA. The basic idea is to buy when the 10-day EMA crosses above the 21-day EMA and sell when it crosses below.

Using the Slower Moving Average as a Trailing Stop-Loss Order

One of the key benefits of the 10-21 EMA trading system is that the 21-day EMA can also be used as a trailing stop-loss order. By placing a stop-loss order below the 21-day EMA, you can limit your potential losses and protect your profits. This also allows you to ride out any temporary market downturns without being prematurely stopped out of a trade. No matter what system you’re using, it’s important to always have a stop-loss in place. This will help you limit your potential losses in case the trade goes against you. You can choose to use either a moving average or a volatility stop, depending on your personal preference and risk tolerance.

Crossovers at the Apex of a Classical Chart Pattern

The 10-21 EMA trading system becomes even more beneficial when the crossovers occur at the apex (or when price gets tight on the right) of a classical chart pattern, such as a the falling wedge, cup with handle or a flag pattern. This is because these patterns often signal a significant change in market direction, and the EMA crossover can confirm this change and provide an ideal entry or exit point.

The Importance of Volume Analysis

It’s also important to remember that volume analysis is an essential part of any successful trading system. By analyzing the volume of trades, you can determine the strength of a trend and the likelihood that it will continue. This information can help you make more informed decisions about when to enter or exit trades.

Avoiding Whipsaw

One potential drawback of the 10-21 EMA trading system is the possibility of experiencing “whipsaw,” which occurs when the moving averages cross back and forth without a clear direction. To avoid this, it’s important to use other indicators in conjunction with the EMA, such as the Relative Strength Index (RSI) or the Moving Average Convergence Divergence (MACD) indicator. These indicators can help provide additional context and confirm the validity of a crossover.


The 10-21 exponential moving average trading system is a powerful tool that can help you achieve your trading goals. By using the 10-day EMA to buy and sell, and the 21-day EMA as a trailing stop-loss order, you can maximize your profits and minimize your losses. But it’s also important to remember that any trading system should be used in conjunction with other indicators and a thorough understanding of market conditions. With the right approach and the right tools, you can become a successful day trader and reach new levels of financial success.
