What Is The Position Sizing In Forex Trading?
Position sizing is the process of determining the units or lots you should trade for a forex pair to manage risk.
We all know the golden rule of forex trading: risk only 1% to 2% of your total capital on any trade.
But what does it mean when you are trading in real time? It means you need to determine the lot size that helps you stay within your risk limit. This process of calculating the right lot size based on capital and risk-taking capabilities is known as position sizing.
Why Is Position Sizing Important In Forex Trading?
The right position size can make your trade the most profitable. However, making a trade based on vague estimates can also be catastrophic for your trading capital. Here are a few more reasons why position sizing is important for forex risk management.
Safety in drawdowns
The forex market is full of ups and downs, especially the downs. That’s why many traders burn their capital faster compared to others. This is where position sizing can help you recover or stop your losses.
When you calculate the lot or unit size before each trade, it gives you time to rethink your decision and stop when losses exceed your limit. With your position size, you risk only a certain % of your capital instead of a large chunk. Thus, one bad trade doesn’t wipe out your account.
Avoid emotional decision
When you see consecutive green bars, it’s very easy to get swayed and risk more capital. This is an emotion-driven decision that can result in huge profit or loss. Therefore, using a position size calculation becomes essential to make rational decisions rather than emotional ones.
Make strategic trades
In forex trading, strategies need to be reevaluated in real time based on the market trends. A position size calculator helps you determine the risk per trade in the forex market. Thus, you can make strategic trade by calculating the lot size and potential profit or loss.
Define your risk and rewards
Forex trading is a risky trade. Thus, you need a tool to determine if the reward from trading is worth the capital you are risking. Position size calculator helps you do exactly that.
How To Calculate Position Size For Forex Risk Management?
To choose the right position size, you need to know the amount you want to trade, your risk capacity, and the stop loss.
Here’s the formula to calculate the position sizing in forex manually:
Position Size (in lots) = Account Risk ($) ÷ (Stop Loss in PIPs × PIP Value per Lot)
Account risk is the percentage amount of your total capital that you want to risk for a single trade.
Let’s understand this formula with an example:
- Account balance: $10,000
- Risk factor: 2%
- Account risk amount: 2% of $10,000 = $200
- Stop loss from the entry point: 40 PIP
- PIP value/PIP based on currency pair: $10 for EUR/USD pair with USD account (standard lot size = 100,000 units)
If you put these values in the formula, it would be:
Position Size (in lots) = $200 ÷ (40 × $10) = 0.5 lot
Based on this calculation, if you want to risk $200, your position size should be 0.5 lot or 50,000 Units.
Methods Of Calculating Position Sizing In Forex
Most calculations use percentage risk per trade to calculate position size. However, there are other position sizing techniques in the forex market. The following are the most popular methods of position sizing for forex risk management:
- Fixed Percentage Risk Model: You only risk a particular % of your total capital to ensure that your trade amount syncs with your balance.
- Fixed Dollar Risk Model: Here, you only risk a certain amount on each trade based on your balance and personal analysis.
- Volatility-Based Position Sizing: This method is used by institutional traders, who focus on the Average True Range (ATR) of a volatile currency pair.
- Kelly Criterion: It is a mathematical formula that uses past data of the currency pair to determine the win rate (W). This win rate is used to determine how much of the total capital should be risked.
- Equity Curve-Based Sizing: You need to analyze your trading balance and performance over time to create an equity curve. If the curve is upward, you trade more, and if it’s downward, you either reduce the position size or halt the trade.
