Measuring volatility in the currency pairs that we are most interested in trading allows you to gauge market conditions better and make more informed decisions. In general, the more exchange rates fluctuate, the higher the market volatility is.

Not only does volatility change from time to time in a particular currency pair, but volatility can also be different at any given time for the various currency pairs. Currency traders need to be aware of market volatility by having a means to assess it. One popular measure is historical volatility, which is related to the standard deviation of past price movements. Another more forward looking measure is observing the implied volatility in the option market for the particular currency pair you are trading.

When it comes to volatility and lot size choices, traders need to be prepared to adjust their trading sizes downwards as volatility rises and upwards as volatility falls in order to take a more uniform degree of risk when they trade.

Astute traders should also consider adjusting stop loss and profit taking orders appropriately to account for substantial shifts in market volatility. In his classic trading book, Trading in the Zone, author Mark Douglas presents an interesting analogy by which to visualize the impact of using larger or smaller lot sizes when trading.

His example asks the reader to equate for a moment their trading lot size with the degree of support they might have underneath themselves while crossing over a valley, although perhaps visualizing a steep ravine might get the point across even better!

Anyway, Douglas asks the reader to consider the impact of an unexpected event on their crossing of this valley. If a trader uses a small lot size relative to their trading account size, then that is like making the crossing over the valley on a broad and firm bridge. Even if you experienced a storm while on the bridge, you will still probably feel secure in your footing and unlikely to fall off the bridge.

In this analogy, the storm is much like the sharp moves or other severe market turbulence that forex traders can experience from time to time. In contrast, you can consider the situation where a forex trader instead uses a large lot size in relation to the amount of money they have decided to put at risk in their trading account. This would be analogous to crossing that same valley on a tightrope wire, where storms — or even a brief gust of wind — can overwhelm you and potentially make you lose your footing and fall.

A useful trading tool to help determine the most suitable lot size to trade is the lot size calculator. This simple calculator tool is readily available online at many forex broker websites, and you can use most forex lot calculator programs completely free of charge.

Lot size calculators have also recently become available as mobile apps, such as the Lot Size Calculator app from Flag One Pte Ltd that is available for Apple iOS mobile devices at the App Store.

This particular app can be downloaded free of charge, only takes up around 4 MB of mobile device storage, and has the following desirable features:. Another useful and closely related type of calculator commonly employed for risk management purposes that you can find online is a position sizing calculator. A mini lot comprises of 10, units of your account currency. If you are a beginner and want to start trading with mini lots, make sure you have fair trading capital.

It is entirely up to you to determine your ultimate risk tolerance. Most brokers offer micro lots as the smallest tradeable Lot. A micro lot has 1, units of the currency used to finance your account. If you finance your account in U. In the case of a dollar-based pair, 1 pip is equal to 10 cents. As mentioned earlier, a PIP is the smallest price change in currency trading. Pairs with JPY have a different approach. The aim of using PIP values per Lot is to decide how much money we gain or lose per PIP, taking into account the amount of currency that we want to trade with.

The first part of the calculation is a straightforward currency conversion; we divide our PIP value by the current exchange rate based on the pair we trade. This way, we will determine how much a PIP is worth in terms of the currency we are trading. The first part of the formula is doing a simple currency conversion; we divide our PIP value according to the pair we trade by the current exchange rate.

This way, we know how much that PIP worth in terms of the currency we are trading is. The second step is multiplying the result by the lot size we are trading with standard, micro, or mini to understand the effect of the previous number we calculated on the total number of currency units we are trading.

We will now calculate some examples to see how it affects the pip value. Knowing the various Lot sizes available and how to measure the pip value will help you create effective risk management strategies while trading.

That is why it is important to select the proper lot size. A lot size that is too large will make the trade riskier and more uncomfortable to hold on to. A lot size that is too small might not generate enough potential gain to be worthwhile.

Micro lots are the smallest tradeable lot available to most brokers. They are lots of 1, units of your account funding currency. If your account is funded in U. If you are trading a dollar-based pair, one pip would be equal to ten cents. Micro lots are very good for beginners who want to keep risk to a minimum while practicing their trading. Before micro lots, there were mini lots. A mini lot is 10, units of your account funding currency. If you are a beginner and you want to start trading using mini lots, make sure that you're well-capitalized.

A standard lot is a ,unit lot. Most forex traders you come across are going to be trading mini lots or micro lots. It might not feel glamorous, but keeping your lot size within reason relative to your account size will help you preserve your trading capital to continue trading for the long term.

In his book Trading In The Zone , trading author Mark Douglas offers a useful analogy between choosing a lot size and walking a precarious bridge or even a tightrope. The idea is that the larger the lot size a trader chooses, the more dramatic and emotional the trading experience is likely to become.

When you first get your feet wet with forex training, you'll learn about trading lots. In the context of forex trading, a lot refers to a batch of currency the trader controls. The lot size is variable. Typical designations for lot size include standard lots, mini lots, and micro lots. It is important to note that the lot size directly impacts and indicates the amount of risk you're taking. Finding the lot size that best balances opportunity and risk is a very important individual decision.

Using a tool like a risk-management calculator can help you clarify your decisions about lot size, but you should do so by factoring in your own risk tolerance and your trading objectives. The trading lot size directly impacts how much a market move affects your accounts. For example, a pip move on a small trade will not be felt nearly as much as the same pip move on very large trade size.

That is why it is important to select the proper lot size. A lot size that is too large will make the trade riskier and more uncomfortable to hold on to. A lot size that is too small might not generate enough potential gain to be worthwhile. Micro lots are the smallest tradeable lot available to most brokers.

In his book Trading In The Zone , trading author Mark Douglas offers a useful analogy between choosing a lot size and walking a precarious bridge or even a tightrope.

The idea is that the larger the lot size a trader chooses, the more dramatic and emotional the trading experience is likely to become. To illustrate this example, a very small trade size relative to your account capital would be like walking over a valley on a very wide, stable bridge where little would disturb you even if there were a storm or heavy rains.

Now imagine that the larger the trade you place, the smaller and riskier the support or bridge under you becomes. When you place an extremely large trade size relative to your account balance, the bridge gets as narrow as a tightrope wire. Any small movement in the market could be like a gust of wind, blowing the trader off balance and leading to disaster.

The forex market is less regulated than other markets, so requirements like minimum account size are typically set by brokerages. The first step in calculating forex profit is to measure the movement of the pair.

Multiply that profit by your lot size and number of lots. If you used leverage, you'll need to subtract what you borrowed from that amount to learn how much profit you'll get to pocket. Mark Douglas.
