The simple moving average is a moving average. It is produced by averaging prices or values across a set number of days or intervals. It is utilised in the financial sector as a technical indicator. The SMA line, formed by the average or SMA values displayed in a chart of asset prices, moves when fresh average values are drawn. Trading professionals may examine price changes and spot patterns and choose appropriate entry and exit points by applying SMA to asset prices based on a chosen range.


How Does This Indicator Work? 


Prices of a particular period are averaged to get the simple moving average. You may manually compute this figure, but most financial websites have it available; your broker's trading app should also have it. In trend-following, many experienced traders frequently employ the simple moving average method. 


Stocks that are heading up should be purchased, while traders should sell those that are trending down. The stock can be in an upward trend if the moving average is rising. If the shorter averages are higher, it indicates the trend is strong. The price should be greater than the 50-day SMA, which is higher than the 200-day SMA. 


One of the best trading techniques is trend-following. Some studies have shown that it has been effective across a range of asset classes for more than a century. Moving averages are acknowledged as a lagging indicator (those which confirm trend changes) for trend-following. So, if the stock price is higher than the moving average (determined from historical data), the stock is already rising upward. Hence, the window of opportunity for profit may be closed. 


Some traders monitor price crosses to enter as soon as feasible. When a lower-number average surpasses or crosses over a high number, this is known as a crossover. For instance, if the stock price was, on average, greater in the most recent quarter than the previous year, it could be a good idea to purchase when the 50 DMA crosses over the 200 DMA.


How Are Simple Moving Averages Used? 


The simple moving average is calculated by adding all the data points and dividing the result by the total number of data points. For instance, a 50-day simple moving average calculates the closing price of the most recent 50 days by adding the closing prices of the last 50 days and dividing it by 50. 


The oldest period is then subtracted from the computation, and new periods are added. Price patterns over a certain period are identified using simple moving averages. Simple moving averages of 10, 50, and 200 days are frequently used as default indicators to determine the short-, medium-, and long-term trends. 


Simple moving averages may be applied to short- and long-term time frames, such as the last 5 or 10 minutes on an intraday chart or on a day or week scale on a yearly chart, respectively. The duration of the moving average influences how sensitive the indicator is to the new data point. The more time a moving average has existed, the longer it takes for changes in the underlying asset's price to affect the moving average's value. The less probable it is that a single data point would produce a misleading signal of a change in trend, the longer the moving average is.


Calculating the Simple Moving Average 


Simple moving average (SMA) is a mathematical moving average created by adding recent prices and dividing that total by the number of periods in the computed moving average. In the closing instance, the share price may be added up over several periods and then divided by the same number of periods; in contrast to the long-term average, which responds more slowly to changes in the underlying security price, the short-term average does so swiftly. Different varieties of moving averages exist, such as weighted moving averages and exponential moving averages (EMA) (WMA).


The simple moving average formula is;


SMA = A1+A2……A /n


The starting data point for the 10-day moving average will be the average of the first 10 days' closing prices. The same is true for a 50-day moving average, where the SMA gathers data for 50 consecutive days to produce an average.


The simple moving average may be calculated over several periods, making it configurable. The stock's average price over the period is calculated by adding the closing prices of the security across several periods, dividing the total by the number of periods, and then averaging the results. A simple moving average reduces volatility and makes seeing a security's price trend easier. 


When the asset's price increases, the simple moving average goes upward. Conversely, a moving average sloping downwards indicates a declining security price if it is trending downward. The smoother the simple moving average, the longer the period for the moving average. 


Trading Strategies Using Simple Moving Average


When the price briefly returns to the 50 EMA after a period away from it, things start to become interesting for trading. It suggests trending price activity, which investors would probably understand if they've closely watched moving averages. 


Moving averages usually close in during sideways price movements and become entangled with the continuing live activity, which is regularly impacted by price. It may be account-killing for moving average-based systems. A trader should only be interested in the price touching the 50 EMA after (roughly) spending some time away from it since this is when it starts to blast off into a nice trend. This is a clear filter for this problem. The graph up top demonstrates this.


Final Take


We learned from this experiment that buying when the close price slips below a short-term moving average and selling when it reverses and crosses above the same moving average are effective moving average methods. Contrarily, it is recommended to purchase when the long-term moving average crosses above it and to sell when it reverses and crosses below it. When utilizing an online trading platform like Share India, traders can easily incorporate technical indicators such as the Simple Moving Average (SMA) to analyze asset prices, identify patterns, and make informed decisions.
