Why Traders Must Understand Equity vs Balance and How to Use This Difference to Assess Portfolio Health

When opening the MT5 trading platform, most traders tend to look at the account balance figure first. However, many may not realise that the displayed figures include two very important values: Balance (account balance) and Equity (portfolio value). The difference between these two numbers is not merely a technical detail, but crucial information that reveals the true health of your trading portfolio at that moment. This article will explain what Equity and Balance are, how they differ, and how to use this difference to assess risk and make conscious trading decisions.

What Are Equity and Balance and How Do They Differ

Balance is the amount of money in your trading account when no orders are open, or the balance after all orders have been closed. This figure only changes when you close an order, deposit money, or withdraw money. Whilst orders remain open, Balance does not change regardless of which direction the price moves.

Equity (portfolio value) is the current value of money in your account, including unrealised profit or loss from open orders (Floating Profit/Loss). The calculation formula is Equity = Balance + Floating Profit/Loss. This figure changes constantly according to market price movements. If you have open orders that are in profit, Equity will be higher than Balance, but if they are in loss, Equity will be lower than Balance.

For example, you have a Balance of 10,000 baht and have opened a buy order on EUR/USD. The order is currently at a loss of 500 baht. Your Equity will equal 9,500 baht even though Balance still shows 10,000 baht. This 500 baht difference is crucial information that tells you how much risk your portfolio is currently exposed to.

Why the Difference Between Equity and Balance Matters

The difference between Equity and Balance is a real-time indicator of portfolio health. If the difference is large, it shows you are carrying high risk from open orders, which could lead to major problems if not managed appropriately.

Warning signs to watch for:

• Equity much lower than Balance indicates you have large floating losses and may be approaching Margin Call or Stop Out
• Equity fluctuating severely whilst Balance remains constant means you are opening positions that are too large relative to your capital
• Equity rarely much higher than Balance but frequently lower suggests you may be letting losses run whilst cutting profits too quickly

Professional traders monitor the Equity/Balance ratio closely. If this ratio drops below 90% (Equity at only 90% of Balance), many will become cautious and consider closing some positions to reduce risk. Monitoring this figure helps you make timely decisions before the situation deteriorates beyond control.

How to Use Equity and Balance to Assess Portfolio Health

Using Equity and Balance effectively requires regular monitoring and analysis, not just looking at the figures once and leaving it at that.

1. Monitor the Equity/Balance Ratio

Calculate the Equity/Balance ratio as a percentage. For example, if Balance = 10,000 baht and Equity = 9,200 baht, the ratio is 92%. If this ratio drops below your predetermined threshold (such as 90% or 85%), treat it as a warning signal that your portfolio is at excessive risk.

2. Observe Periods When Equity Is Lower Than Balance

If Equity remains lower than Balance for an extended period of several days or weeks, it indicates you are holding losing positions for too long. This may signal that you are reluctant to cut losses or are hoping the market will reverse. Allowing Equity to remain below Balance for extended periods is risky behaviour that professional traders try to avoid. If you notice this pattern in your own statistics, review your Stop Loss strategy immediately.

3. Use Equity as a Criterion for Opening New Orders

Instead of using Balance as the basis for calculating Lot Size, some traders choose to use Equity instead, because Equity reflects the true current capital position. Using Equity in calculations makes you more cautious when you have losing orders open and helps prevent you from taking excessive risk in unfavourable situations.

4. Record and Analyse the Equity Curve

The Equity Curve is a graph showing changes in Equity over time. Viewing the Equity Curve helps you see the overall picture of whether your portfolio is growing steadily or fluctuating wildly. If the Equity Curve shows severe ups and downs, it indicates you may be using excessive risk or your strategy lacks stability. Platforms such as Thaifxbook can display the Equity Curve and other statistics from your MT5 trading account in real time, so you don't have to record manually and can analyse immediately.

Case Study: When Traders Look Only at Balance and Miss Warning Signs

There are many traders who look only at Balance and think their account still has plenty of money left, but the reality is that their Equity has dropped so much they are close to Margin Call. For example, one trader had a Balance of 50,000 baht but had opened multiple positions with combined losses of 15,000 baht, leaving Equity at only 35,000 baht (70% of Balance). Most brokers will issue a Margin Call when Equity drops below 50-30% of Margin Required. If this trader had not been monitoring Equity, he might not have realised he was in a critical situation until the broker forcibly closed positions (Stop Out), resulting in substantial capital loss.

Conversely, traders who monitor Equity closely will see warning signs early and can decide to close some losing positions to maintain Equity at a safe level, or stop opening new positions until the situation improves. Having the psychological discipline to accept small losses to prevent major damage is an essential skill that all traders must practise.

Tools and Methods to Monitor Equity vs Balance Effectively

Monitoring Equity and Balance with the naked eye on the MT5 platform may not be sufficient, especially if you have multiple accounts or need to analyse historical data. Tools that make monitoring easier include:

• Trading statistics platforms such as Thaifxbook that connect to MT5 accounts and automatically record Equity, Balance, and other statistics. You can view Equity Curve graphs, Drawdown, and other indicators in one place
• Trading journals where you record Equity and Balance values daily to create an overview and analyse long-term patterns
• Risk management applications that calculate the Equity/Balance ratio and send alerts when figures drop below set thresholds

Using these tools means you don't have to remember or calculate manually, and can focus on making trading decisions much more effectively.

Summary: Equity and Balance Are Windows to True Portfolio Health

Balance tells you how much money you have when no orders are open, but Equity tells you how much money you truly have right now. The difference between these two figures is the most important warning signal indicating whether your portfolio is at risk. Successful traders don't just look at the attractive Balance figure, but monitor Equity closely, analyse the Equity/Balance ratio, and use this information to make conscious decisions about opening or closing orders. Understanding and utilising this difference will help you preserve capital for the long term and grow sustainably in the Forex market.
