The Simple Moving Average (SMA) is the most basic and widely used type of moving average. It’s calculated by taking the arithmetic mean of a given set of prices or data points over a specified period.

SMA = (P1 + P2 + ... + Pn) /n

Where

P1, P2, ... , Pn = prices of data points

n = number of periods

When a new SMA is calculated for a new candle stick, the oldest data point P1 is removed from the original data points (P1 + P2 + ... + Pn) and a new price Pn+1 is added to form a new SMA:

SMA_new = (P2 + ... + Pn + Pn+1) /n

If Pn+1 < P1, SMA line will become downward trend, or if Pn+1 > P1, SMA line will become upward trend. This logic help us predict the moving direction of SMA line which will form the prices trend in the future.

So it's important to highlight the "P1" candle stick for SMAs of different periods to help us predict the trend of SMA lines.

Since SMA5, SMA10, SMA20, SMA60, SMA120, SMA250 are the most popular SMAs, this indicator marks the "P1" candle stick for all of them by default, but you can optionally disable them.
