The pricing of options is a huge subject and we won't go into it beyond the barest detail here. Theoretical models using forecast volatilities often produce results that differ from actual traded options prices. Using the price of an option in the market, you can work backwards to calculate an implied volatility. If you are looking for a Forex volatility index, there are also currency-related indices available.
That is because when we talk about volatility in terms of economic indicators, we are referring to historical volatility. A volatility indicator helps you gauge the state of a market and in a general sense judge whether it suits your needs. You see, if you're the kind of trader looking for a steady, quiet ride, a low-volatility market may suit you better. Going beyond this usage of determining a market's suitability, volatility indicators also have more specific uses.
If you're wondering which Forex volatility indicator MT4 has to offer, the answer is, there are several available. Learn about how our Volatility Protection service keeps you safe from volatility risks. Parabolic SAR was developed by J. Welles Wilder, a major innovator in the field of technical analysis.
The indicator's name stands for parabolic stop and reverse and attempts to identify good entry and exit points. It's important to note that it was designed only for trending markets and is, therefore, not effective in range-bound markets. Welles Wilder made his name as a technical analyst in the field of commodities, but he first trained as an mechanical engineer.
We can see this part of his background creep in with the usage of the term parabola. The characteristic curve results from the effect of gravity decreasing the projectile's velocity.
The best way to perform this kind of experimentation is in a risk-free environment, such as our demo trading account. Each time the market reaches a new high in an uptrend or a new low in a downtrend, we increase the AF by a step. The default value for this maximum in MetaTrader 4 is 0.
Another volatility indicator that comes with MetaTrader 4 is the simply-named momentum indicator. Its value tells you the percentage change of the current market price from the price a set number of periods prior.
The indicator gauges the strength or weakness of a trend, thus identifying possible reversal points. As long as the magnitude of the momentum value remains large, we would expect the trend to continue. If the value begins to tail off and heads back toward 0, it may be a sign that the trend is breaking down. While the momentum indicator is a straightforward measure of volatility, it does also measure direction as well as rate of change.
A Forex volatility meter that dispenses with direction and tells you purely about the magnitude of volatility is Average True Range indicator , or ATR. Volatility channels are a type of indicator that plot volatility-related lines above and below the market. The most well-known volatility channel is the Bollinger band, though the Keltner channel indicator is another effective type.
But if you want a more comprehensive choice of volatility channels, you should consider the MetaTrader 4 Supreme Edition plugin. MT4 Supreme Edition offers the aforementioned Keltner channel indicator, alongside an impressive bundle of other helpful tools. If the market breaks out beyond this boundary, we are alerted to an unusual occurrence and can plan our trades accordingly. Bollinger bands use multiples of the standard deviation to calculate how far away the bands lie from the central measure of price.
A standard deviation is a statistical measure that quantifies the variation of a set of numbers. The more volatile a market, the wider the variability of prices will be in a certain period If you're interested in reading more on Bollinger bands, you can find a full explanation in our rundown of the Most Important Forex Indicators. It isn't necessarily a case of which one is the best, but how best to use them to meet your needs. For example, we said earlier that parabolic SAR only really works effectively when the market is in a trend.
You could perhaps use the momentum indicator as your primary indicator to first establish whether this condition is met. The ADX Indicator could also be used to serve this purpose.
