Understanding the Forex Position Sizes

We often talk about the price of forex pairs or fx symbols but there is other equally important information to be decided for each trade. The total amount per order or the size of the trade is one key aspect. It is related with the willingness to take risk, and there is no general rule to it, as other factors must be considered. This article explores ways for you to understand how forex position sizing can be good for your trading.

Quick tips.

#1 Position Size = number of contracts/units of an instrument you buy or sell. However, Position Size and Risk Amount are not the same.

#2 Contract or Lot, is a unit of measure for position volume, which is a fixed amount of the base currency on the Forex market. The volume is always indicated in lots, and the size of lots directly affects the level of risk. The standard lot is 100,000 currency units, typically has a value of $100,000 if we take trading in US Dollars as an example.

As a very high risk operation you can lose money very fast if you enter a large investment position at once. Most of the research information about position sizing brings a tip to avoid dealing with more than two percent (2%) of your principal each trade. That means that if you have $5,000 you should never use more than $100 to invest on each order.

When it comes to forex trading, you might ask how much does $100 represent in units or lots? First, we need to know that a typical forex contract is a bundle of 100,000 units equal to one standard contract.

On Forex trading, positions can only be opened in certain volumes of trading units called contracts or lots, depending on the forex broker. A trader cannot buy, for example, 1,000 euros exactly, they can buy 1 lot, 2 lots or 0.01 lots, etc.

As a trader, it is crucial you know how many units you are exposed to when placing a trade in the broker. Depending on the type of contract you trade, there is a specific quantity of the underlying assets in each Unit.

Below are three of the most common forex contract sizes and their underlying units:

  • One Standard Contract or Lot = 100,000 units of currency;
  • One Mini Contract or Mini Lot = 10,000 units of currency;
  • One Micro Contract or Micro Lot = 1,000 units of currency;
  • One Unit of Contract = 1 unit of currency.

Depending on the Broker, we can also use these following conversion:

  • Mini Lot: 0.1 Standard Lot;
  • Micro Lot: 0.01 Standard Lot;
  • Unit of Contract = 0.0001 Standard Lot.

The standard lot (or contract) in Forex trading is 100,000 units of base currency. For example, if the EUR/USD rate is equal to 1.1845, then the position with a volume of 1 lot will be opened for 118,450 units of the base currency, i.e. this is how many US dollars you need to buy 100,000 euros.

Example of calculating the position size:
So, let’s suppose that you have an account in my forex broker that is in USD and you entered a long order with a Standard lot of EUR/GBP that moved 50 pips in the way you wanted (consider EUR/GBP = 0.8964). So if my position size is 100,000 units of Euro, 50 pips in GBP means 50/0.8964 in EUR(55,8 pips in Euro). The amount of money profited in EUR is 100,000*0,00558 (558 Euros), to change that to our base account we must multiply to the quotation of EUR/USD(consider 1.1249). So 558*1.1249 is the amount of money profited in USD which is 627,69 dollars.

The is important to remember is that forex and CFDs (Contracts for Difference) are other Over the Counter (OTC) markets and contract sizes and other trading specifications are not standardized. Furthermore, the ability to hedge positions may also vary, depending on where you trade.

Choosing the right trade size in forex

We discussed standard contracts earlier, which are designed for larger companies and investors, and is why they are 100,000 units in size, compared to the smaller mini and micro contracts.

The ability to offer options to smaller investors by brokers is why mini contracts for 10,000 Units size are offered. Furthermore, retail traders seeking to test a trading strategy or open smaller trade amounts that are more specific, can trade micro contracts of 1,000 units. It allows trades to be fine-tuned, as you can buy a contract of EUR/USD and some mini contracts to reach as close as possible the target position size that you either want to hedge or to open a new trade position.

It is important to understand that the position sizes are proportional to the speed you will use your account margin. We discussed in earlier posts that most brokers allow you to leverage your margin trading, to be able to open positions that are bigger than your total amount of principal in your available balance. This form of leverage can lead to quick losses and can consume your resources faster.

We must be aware that each day new market opportunities occur, and if you use all your margin with too big positions sizes in a few trades, you will probably miss new signals or need to put more money in your account to seize them.

The position size is the key variable to set the level of risk of your forex trading operations. That is why we never recommend exposures bigger than one percent of your principal in the broker.

It is very important to be consistent in your investment strategy, because you need to be able to compare the results of your trading history over time. If you change more than one parameter each trade, you can miss important information about what happens (especially if the trade has a bad result). Keeping a detailed journal of your trading and the decisions to change parameters can help you better understanding the outcome and what to consider tweaking.

On the other hand, for many forex traders there is too much information to track, and that is why Wiseinvest has set out to help the trading community with the launch of Wiseinvest automated AI trading system and AI signals, which helps do a lot of the work for you, in terms of finding trading opportunities and knowing when to enter and exit the market.
