Equity
Equity is the current real-time value of a trading account, calculated as the account balance plus or minus all unrealized (floating) profits and losses from open positions.
Quick Definition Box
Equity is the "live" value of your trading account at any given moment. It changes with every tick of the market because it includes unrealized gains and losses on open trades. Your balance only changes when you close a position; your equity changes constantly. Understanding equity is essential for managing margin, avoiding margin calls, and sizing positions correctly.
Detailed Explanation
To understand equity, you must first distinguish it from balance. The balance is the amount of money in your account after all closed trades have been settled. It does not reflect open positions. Equity, on the other hand, is a dynamic figure: it equals balance plus the floating profit or loss of all currently open trades.
The formula is simple:
Equity = Account Balance + Unrealized Profit − Unrealized Loss
For example, if your account balance is $10,000 and you have one open position with a floating profit of $500, your equity is $10,500. If that same position instead shows a floating loss of $300, your equity is $9,700.
Equity is the figure that brokers use to determine whether you have enough margin to keep your positions open. When your equity falls below the required margin level, you receive a margin call — and if it drops further, your broker will automatically close your losing positions to prevent your account from going negative. This process is called stop-out.
Equity also matters for money management. Many professional traders base their risk calculations on equity rather than balance. For instance, if you apply the two-percent rule, you risk 2% of your current equity, not your initial balance. This approach automatically adjusts your position size to account for both winning and losing streaks. If your equity grows, you risk more in absolute terms; if it shrinks, you risk less, which helps protect your capital during drawdowns.
Another important nuance: equity is not a static number even when you have no open positions. If you have no trades, equity equals balance. But the moment you open a trade, equity starts fluctuating. This is why traders often monitor equity curves — a line graph of equity over time — to evaluate the performance of their strategy. A steadily rising equity curve suggests consistent profitability; a volatile or declining curve signals poor risk management.
Real-World Example
Let’s walk through a concrete scenario.
Step 1 — Starting point:
You deposit $5,000 into a trading account. Your balance is $5,000, and since you have no open positions, your equity is also $5,000.
Step 2 — Opening a position:
You buy 0.5 lots of EUR/USD at 1.1000. Your broker requires a margin of 1%, so the margin needed is $550 (0.5 lots × 100,000 units × 1.1000 × 1%). Your balance remains $5,000, but your equity now depends on the market price.
Step 3 — Floating profit:
The price moves to 1.1050. Your position gains 50 pips. For 0.5 lots of EUR/USD, each pip is worth $5, so your floating profit is $250. Your equity is now $5,250 ($5,000 + $250). Your balance is still $5,000 because you haven’t closed the trade.
Step 4 — Floating loss:
The price reverses to 1.0950. Now you have a floating loss of $250. Your equity drops to $4,750. Your balance remains $5,000.
Step 5 — Closing the trade:
You close the position at 1.0950. The floating loss becomes realized. Your balance is now $4,750, and your equity equals your balance again ($4,750).
Notice how equity moved in real time while balance stayed static. If your equity had fallen to the broker’s stop-out level (say, 50% of required margin), your position would have been closed automatically, potentially locking in a larger loss.
Why It Matters for Traders
Equity is the single most important number for risk management because it reflects your true financial standing at any moment. Here’s why it matters:
- Margin calculations: Brokers use equity to calculate margin level (equity ÷ used margin × 100). A margin level below 100% means you cannot open new positions; below the stop-out threshold, your positions are closed.
- Position sizing: If you risk a fixed percentage of equity per trade, your position size automatically adapts to your account’s performance. This is a core principle of the Kelly criterion and other advanced money-management formulas.
- Drawdown measurement: Drawdown is calculated from peak equity to trough equity. If you only track balance, you might miss intra-trade losses that never appear on your balance but still affect your psychological state and decision-making.
- Performance evaluation: An equity curve is a more honest measure of a strategy than a balance curve because it includes open-trade volatility. A strategy that shows a smooth balance curve but wild equity swings is risky.
Traders who ignore equity often make the mistake of thinking they have more money than they actually do. For example, if your balance is $10,000 but your open positions show a floating loss of $2,000, your equity is $8,000. If you open another position based on the $10,000 balance, you are over-leveraging and may trigger a margin call.
Common Misconceptions
Misconception 1: "Equity and balance are the same thing."
They are only equal when you have no open positions. As soon as a trade is open, equity diverges from balance due to floating P/L. Many beginners check their balance and think they are profitable, only to be surprised by a margin call.
Misconception 2: "A floating loss is not a real loss until I close the trade."
While it’s true that a floating loss is not realized, it still reduces your equity and your available margin. If the market moves against you enough, the broker will close your position automatically, turning the floating loss into a realized one. Treating floating losses as "not real" is dangerous.
Misconception 3: "Higher equity always means I can trade bigger."
Equity growth does not automatically justify larger positions. Risk management rules like the two-percent rule or the Kelly criterion suggest that position size should be based on a percentage of equity, but also on the probability of success and the risk-reward ratio of each trade. Increasing size simply because equity is higher can lead to ruin if the strategy’s edge is weak.

How XM Compares
XM, like most regulated forex brokers, displays both balance and equity in the trading platform. The equity figure updates in real time and is used to calculate margin levels and trigger stop-outs. XM’s standard practice is to close positions automatically when margin level falls below a certain threshold, which is a common industry standard. However, specific margin requirements, leverage limits, and stop-out levels can vary by account type and regulatory jurisdiction. Traders should always verify current terms, leverage policies, and margin rules on XM’s official website before trading.
