How to Determine Size Position in Forex Trading

Forex trading

The Size Position in Forex Trading you take in your trades is regarded to be the single most critical aspect in developing equity in your trading account. In reality, position sizing is responsible for the trade’s fastest and most exaggerated returns. Here, we take a provocative look at risk and position sizing in the forex market and provide some advice on how to make the most of it.

What Is Position Sizing?

The amount of units an investor or trader invests in a given investment is referred to as position size. When evaluating suitable position sizing, an investor’s account size and risk tolerance should be considered.

The number of lots, as well as the kind and size of lot you purchase or sell in a trade, affect the size of your position:

A micro lot is made up of 1,000 units of a certain currency.

10,000 units make up a micro lot.

A typical lot size is 100,000 units.

The Importance of Position Size

In order to trade forex successfully, you must first determine the size of your position. If you take on too much risk, a few bad transactions might wipe out your whole account. Even the most successful traders suffer losses. Your account will not grow if your position size is too modest, and you will not accomplish your financial goals.

Your results will be lower than they would be if you traded with the optimal position size.

There are Various Ways to Determine Position Size in Forex Trading:

1.Fixed lot Size:

The notion is that for each deal, a trader employs the same trading volume in lots. For individuals who are new to trading, this method is straightforward to comprehend. It is suggested that you pick modest trade sizes. If the amount of your account drastically changes, you can alter the position size. The pip value will always be the same for you.


Your account balance is $500. This amount will be enough to conduct 50 transactions of 0.01 lot each at a ratio of 1:100. Each trade will necessitate a $10 margin requirement.

If you always utilize the same lot size, your account will rise steadily. This is a wonderful alternative for people who find it difficult to adjust to the exponential expansion of their transaction sizes due to increased stress levels. More experienced traders, on the other hand, may prefer a strategy that allows for greater flexibility and account increase.

2.Equity Percentage (%):

You determine the size of your stake as a percentage of your equity in this situation. As your equity grows, so does the size of your positions. This might lead to a geometric increase in the size of your account. At the same time, keep in mind that your account’s decreases will be greater as a result of losing transactions.

It is recommended that you should not invest more than 1-2 percent of your whole investment in a single deal. In’t manner, even if some of your transactions fail, you won’t lose all of your money and may continue trading.

Here’s a formula for calculating the size of a position in lots:

Equity * Risk (percentage) / Contract Size * Leverage = Lots to trade


You have $500 and determine that 2% of your account is an acceptable risk threshold. With a leverage of 1:100, you must select ($500 * 0.02) / 100,000 * 100 = 0.01 lots.

You may trade ($1000 * 0.02) 100,000 * 100 = 0.02 lots with $1000 in your account.

For smaller accounts, this strategy is not the best solution. Even for the smallest lot size, the risked percentage may be too tiny to function as a buffer if you have a huge loss. As a result, you’ll be obliged to breach your risk management rules and allocate additional capital in order to continue trading.

Furthermore, because this method ignores what is happening on the price chart, the magnitude of the Stop Loss it permits may be excessive.

Because position size is determined by equity, a loss reduces position size, making it more difficult for a trader to recover the account after a loss. Simultaneously, if the account grows too large, the size of each trading route grows too large as well.

Equity Percentage with Stop Loss:

Your position size is decided not only by the specified % risk of every trade but also by the distance between you and your stop loss. Let’s divide this down into three steps.

Step 1: The advice remains the same: don’t risk more than 2% of your deposit/equity on a single deal.

A 2% risk will cost you $10 if your equity is $500.

Step 2: Determine the location of the stop loss for a certain trade. Then calculate the pips difference between it and your entry price. This is the number of pips at stake. Calculate the optimum position size using this information and the account risk limit from step 1.

Your trading risk is 50 pips if you purchase EUR/USD at 1.1100 and put a stop loss at 1.1050.

Step 3: Now you may calculate the size of your position depending on account and trade risk. In other words, you must decide the number of lots to trade in order to achieve the risk percentage you desire while maintaining the stop distance that is appropriate for your trading strategy.

It’s crucial to alter your position size to match your intended stop loss, not the other way around. Every transaction will have the same risk, but the position size may differ due to varying stop loss distances.

Remember that for each pip movement, a 1,000-unit lot (micro) is worth $0.1, a 10,000-unit lot (mini) is worth $1, and a 100,000-unit lot (standard) is worth $10. This is true for any pair in which the USD is mentioned second, such as the EUR/USD. These pip values will change somewhat if the USD is not stated second. Trading on a regular lot is only suggested for experienced traders.

Use the Following Formula:

Lots to trade = Equity * Risk percent (%)


You’ll be able to exchange $500 * 0.02 / (50 * $0.1) = $10/$5 = 2 micro lots, as it turns out. Because the pip value used in the computation was for a micro lot, the result is in micro-lots.

It’s possible that your next transaction will just have a 20-pip stop. Your position size will be $10/ (20x$1) = $10/$20 = 0.5 mini lots or 5 micro-lots in this example.

If you employ this strategy, your position sizes will rise according to the increase in your account equity (and vice versa if your equity declines) and will be adjusted for the current chart condition. However, if your account is tiny, this alternative, like the simple equity % method, may leave you with little space for movement.

Furthermore, if your trading strategy does not require you to know the exit levels ahead of time, this approach will not be suitable for you.

Summary :

In summary, you should select the one with which you are most comfortable. As you can see, each methodology has its own set of benefits and downsides, so what works for one trader may not work for another. Much will be determined by your trading strategy:

Does it suggest large profits but also a high danger of large drawdowns, or does it provide several possibilities for lesser profits? This will influence your selection.

Although all of these calculations for position sizing may appear tedious, it is in your best interest to do them. Knowing how to select the appropriate position size can help you become a more disciplined trader with effective risk management. This is how you may maximize your earnings while reducing your losses!
