They must first select the appropriate value for their variable before they can use a SMA Indicator. There are only two things to think about: the time frame and the cost. They will select a period value, such as 30, and for the price set, they will be able to select the opening price, closing price, high price, low price, or any combination of these three for each period. If they choose '30' and 'closing price,' the indicator will calculate the average closing price over the previous 30 time periods and divide that total by 30. A simple moving average indicator is most useful when there is a clear trend that has been going on for a long time. Traders pay close attention when the Simple Moving Average (SMA) crosses over the pricing candlesticks because this is one of the most important points of reference. If prices rise further and a crossover occurs, this is interpreted as a buy signal. When prices are falling and a crossover occurs at the same time, it is usually interpreted as a signal to sell the asset.
An SMA chart, like any other type of technical indicator, will never be completely accurate. Although false signals are possible, positive signals are sufficiently reliable to provide any forex trader with a competitive advantage. It is possible to develop the ability to interpret and comprehend SMA alerts over time, and it is a good idea to supplement a SMA indicator with other technical indicators, such as a moving average convergence divergence (MACD). Multiple technical indicators should always be used in conjunction with one another. This is because the various ways in which trends can be evaluated will help to confirm or refute potential price changes.

EMA and MACD are the basic indicators with which to start investing in Forex.
