To further simplify SMA, it is nothing but the average price of an instrument for a specified period of time (in this case, average price of an instrument for a period of 10 days).

It is also important to note that the term ‘Moving average‘ is usually referred to an SMA.

For example, traders focus on long positions when the current price moves above the 200 day moving average and focus on short positions when the price falls below this line. In the above chart, the 200 day SMA is the silver line. As indicative, it clearly outlines the bullish and bearish runs on the instrument (SILVER).

EMA’s and SMA’s form the critical elements of the MACD which is used as an indicator by many traders.

The above chart set up works perfectly find with 15 minute charts, up to 1 hour charts.
