Standard deviation is a statistical term that refers to the volatility of price in any currency and measures how widely prices values are dispersed from the mean or average.

If you’ve been in the forex market for some time, then you probably know all too well how dangerous spikes in volatility can be. Such spikes can easily result in severe losses in one’s trading positions. This is where a good understanding of standard deviation can prove helpful. How is this so?
Simply put, standard deviations are used to determine the inherent volatility of a currency pair before placing a trading order. The latter is a common technique in statistics that measure the variance of a dataset from its’ original value. The more a value drops in proportion to its’ initial value, the bigger the standard deviation.
Today, the standard deviation applies to many areas of discipline such as academics, healthcare, and yes, forex trading! In the case of the latter, standard deviations are primarily used to measure volatility. Many traders use it to visualizing the relationship between a currency’s closing price to its average or mean value over a specific period.
To use standard deviation in forex, traders need to establish three things:
Determine the closing price over a certain period Establish the mean value for the dataset Calculate the difference between the closing price and the mean value
Of course, calculations for standard deviation is much more complicated than it appears to be. For this reason, traders often depend on popular trading platforms that usually have a deviation tool that handles the calculations for them.
How to calculate the forex deviation levels ?
There are several methods involved in computing the standard deviation in the forex of values set. These methods are given below:
• Select a particular observation window.
• Calculate the arithmetic mean for the particular price tag over the limited course of the window.
• Estimate the deviation of the price from the mean value. • Find the square of the values from step three.• Add the values from step four.
• Now, divide them by the total; the number of periods to find the variance.
• Find the square root of the value of variance to find the standard deviation.
We can use the yielded value of standard deviation in eruption for ’ period s of time.
The equation is: i=1N*(x – x)2
Here x is the price, ‘ is the standard deviation, x is the mean of the price values. This method is used by the MT4 indicator.
Calculation of standard deviation in MQL4
StdDev (i) = SQRT (AMOUNT (j = i – N, i) / N)
AMOUNT (j = i – N, i) = SUM ((ApPRICE (j) – MA (ApPRICE (i), 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 till 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.

Low deviation means that the currency’s closing price is not far from the established value. This would suggest limited volatility and a current consolidation phase as a result of an eventual breakout, low market participation, or irregular price action.
A high deviation means that the closing price is quite far from the original mean value. This would suggest extreme price volatility, which brings about higher risks and possible rewards.
The great thing about applying standard deviation in your forex trading strategy is that its’ a highly instinctive vehicle for gauging one’s trading risk and appetite. Once you’ve established that your currency pair is under low or high deviation, you can then adjust your trading strategy as you see fit.
