How To Calculate Lot Sizing, Pips, & Risk-To-Reward In Forex 

When trading the financial markets from South Africa, it is essential to understand lot size, pips, and risk-to-reward ratio. This article explains what these terms mean and how to calculate lot size in forex, forex pip value calculation, and the risk-to-reward ratio in forex, helping you become a more well-rounded trader.

What is Lot Size in Forex? 

The term “Lot” refers to the size of a trade. More specifically, a “Lot” in forex trading is the amount of currency units bought or sold in a trade.  

Lot sizing plays an immense role in risk management. The differences in lot sizes fall into 4 categories: standard, mini, micro, and nano ^[1]. 

	Lots	Units
Standard	1 Lot	100,000
Mini	0.1 Lot	10,000
Micro	0.01 Lot	1000
Nano	0.001 Lot	100

Using EURUSD as an example, when traders purchase 1 standard lot of EURUSD, it equates to buying 100,000 units of the base currency (EUR). If the price of EURUSD is 1.2000 (1 Euro = 1.2 USD), and a trader purchases 1 lot, it equates to the purchase of $100,000 Euros for $120,000 US Dollars.  

Mini, micro, and nano lots are smaller divisions of the standard lot. Traders use a smaller lot size to minimise risk and avoid big losses. A mini lot and micro lot account for 10% and 1% of a standard lot, respectively. A nano lot is less common and is only offered by select brokers. This is essential knowledge when calculating lot size in forex accurately. 

What Are Pips? 

A “pip” is the unit of increment in a forex currency pair and is an acronym for percentage in point.  Most forex currency pairs are up to four decimal places long, and a pip is in the fourth decimal place. 

However, do note that the pip for forex pairs with the Japanese Yen in them are usually at the second decimal place instead of the fourth. The reason Yen has a unique exception to the fourth decimal place rule is that 1 Japanese Yen is worth 1/100 of the US Dollar. Understanding this is key to pip value forex calculations and planning trades effectively.

Knowing the forex pip value calculation helps traders estimate potential profits or losses before entering a trade.

Combining Your Understanding of Lot Sizes With Pips 

A rule of thumb: For every standard lot opened, a one pip movement is worth $10.  

In the same vein, a one pip movement on a mini lot is worth $1, and $0.10 on a micro lot.   

Using the EURUSD example from Figure 4, if a trader follows the above idea and opens a 1-lot buy position, the expected loss would be $ 1,360 (136 pips × $10/lot) and the expected profit would be $ 2,720 (272 pips × $10/lot).   

This is where calculating pips with lot size and pip value per lot becomes essential for precise trade management. Understanding pip value in forex is crucial for accurate position sizing and effective risk control.

What is the Risk-To-Reward Ratio? 

Traders use the risk-to-reward ratio in forex to calculate the expected profit of a forex pair against the expected loss. Seasoned traders use this risk management tactic to analyze investment opportunities and say it’s a key factor in trading success.  

To find out what a trade’s risk-to-reward ratio is, simply divide the expected return by the expected loss.  

Figure 4 shows EURUSD on the H4 chart. If one were to plan a buy trade idea, the entry price, the expected loss price (stop-loss), and the expected profit price (take-profit) should be planned in advance. In the example above, the stop-loss price relative to the entry is 136 pips, while the take-profit price relative to the entry is 272 pips. Dividing the take-profit from the stop-loss generates a risk/reward ratio of 1:2. 

Although it may seem that the higher the risk-to-reward ratio, the more profits can be made, setting unrealistic risk-to-reward targets, such as 1:20, may not be practical. Traders should always use a realistic risk-to-reward ratio in forex metrics to execute strategies confidently.
