the standard deviation (stddev) technical indicator is a measure of market volatility. it quantifies the extent of price fluctuations relative to the moving average. a high indicator value indicates a volatile market with prices dispersed from the moving average, while a low value suggests the opposite.Also recommended: Mean Deviation Index (MDI) by William Blau - Enhanced MT5 Indicator - similar indicator with strong performance on MetaTrader 5.
this indicator is often used as a component in other indicators. for instance, when calculating bollinger bands, the symbol's standard deviation is added to its moving average.
the market's behavior can be understood as alternating between periods of high trading activity and lethargy. consequently, the indicator can be interpreted as follows:
- when the value is extremely low, indicating market inactivity, a surge in activity can be anticipated.
- conversely, if the value is exceptionally high, it implies that the market activity will likely subside soon.
calculation:
stddev (i) = sqrt (amount (j = i - n, i) / n)
amount (j = i - n, i) = sum ((apprice (j) - ma (apprice , n, i)) ^ 2)
where:
- stddev (i) - standard deviation of the current bar
- sqrt - square root
- amount(j = i - n, i) - sum of squares from j = i - n to i
- n - smoothing period
- apprice (j) - the applied price of the j-th bar
- ma (apprice (i), n, i) - any moving average of the current bar for n periods
- apprice (i) - the applied price of the current bar
