SMA line setup is actually very simple? Master these 3 steps to quickly get started with moving average trading

Many novice traders get headaches when they see moving averages, but setting up the SMA line is not as complicated as you might think. As long as you understand the principles and use the correct parameters, simple moving averages (SMA) can become a powerful assistant in your trading decisions.

What is a Simple Moving Average (SMA)?

The simple moving average is one of the most basic indicators in technical analysis, abbreviated as SMA. Its core logic is straightforward: add up the closing prices over a certain period, then divide by the number of days to get a data point. Connecting these points forms a trend line.

For example, calculating a 10-day SMA:

• First data point = (Sum of closing prices from day 1 to day 10) ÷ 10
• Second data point = (Sum of closing prices from day 2 to day 11) ÷ 10
• And so on…

What are the benefits of doing this? It filters out the noise from price fluctuations, allowing you to clearly see the true upward or downward trend of the asset. When the SMA slopes upward, it indicates rising prices; downward slope indicates a decline.

However, there’s a downside to be aware of: SMA reflects past price movements and has a lag. When a signal appears, the market may have already moved significantly. Therefore, in choppy markets, prices often cross the moving average frequently, which can generate many false buy or sell signals.

How to set up an SMA line? Three quick steps

To trade with SMA, the first step is to learn how to set it up. The process is quite standardized:

Step 1: Open the technical indicator panel
Find the indicator button in your trading software and access the indicator library.

Step 2: Add the moving average indicator
Search for or select “Moving Average,” then click to add. A line will appear on the chart.

Step 3: Adjust the parameters
Right-click on the line and choose “Settings.” Set the period according to your trading cycle (for example, 20 for a 20-day SMA), and you can also change the color and thickness in the “Style” options.

Advanced tip: It’s recommended to set multiple SMAs (such as 20, 50, 200 days) with different colors to better observe the interaction between short-, medium-, and long-term trends.

Two core strategies for trading with SMA

Strategy 1: Price crossing the SMA

• When the candlestick crosses above the SMA, it’s considered a buy signal
• When the candlestick crosses below the SMA, it’s considered a sell signal

This method is very intuitive and suitable for beginners to quickly get started.

Strategy 2: SMA Golden Cross and Death Cross

• Golden Cross: When a short-term moving average (e.g., 20-day) crosses above a long-term moving average (e.g., 50-day or 200-day), it indicates a bullish signal
• Death Cross: When a short-term moving average crosses below a long-term moving average, it indicates a bearish signal

This strategy is more suitable for medium-term trading, and its signals are relatively reliable. For example, when the 20-day SMA crosses above the 50-day SMA, it suggests short-term momentum is starting to dominate the long-term downtrend, signaling a market reversal to the upside. Conversely, the opposite indicates a downtrend.

How to use different period SMAs

Choose different SMA periods based on your trading timeframe:

• Short-term (10-day or 20-day SMA): suitable for intraday or a few days trading
• Medium-term (50-day SMA): suitable for holding positions for 2-3 weeks
• Long-term (200-day SMA): reflects multi-month major trends and is often used to judge market bull or bear conditions

Final advice

Even though setting up an SMA line is simple, don’t rely on it as your only trading tool. No single indicator can predict the market with 100% accuracy. The best approach is to combine it with other indicators like RSI, MACD, etc., which can help filter out false signals and improve your win rate.

At its core, technical analysis is a game of probabilities. SMA just helps increase your chances of winning; disciplined trading and risk management are the keys to long-term consistent profits.
