Equity
Equity
Equity in trading refers to the total market value of a trader’s account, including both the initial deposit and any unrealized profits or losses from open positions. It is a key metric for assessing an account's financial health, depicting the real-time portfolio value of a trading account and factoring together all open positions. Equity measurements play a crucial role in risk management, margin calculations and trading strategies.
Tracking equity is especially important in forex trading, where account equity can fluctuate rapidly due to leveraged positions. In leveraged trading, a small change in market price can significantly impact equity, increasing both potential gains and losses. Maintaining a healthy account balance and managing liquidity is essential to sustaining trading activity and avoiding margin calls.
Equity formula
Equity = Balance + Unrealized Profits/Losses
Balance = Total value from closed trades and deposits/withdrawals
Unrealized Profits/Losses = Total value of open positions based on current market value
Equity vs. balance: key differences
Equity reflects a trader’s total account value, changing in real time based on the floating profit or loss of open positions. Meanwhile, account balance shows an account value based only on closed trades and deposits/withdrawals.
Equity fluctuates with market movements, while balance remains static until traders are closed or funds are added or withdrawn. A positive equity level reflects healthy net worth within the account, while negative equity can lead to forced liquidation.
How equity affects margin and leverage
Equity is used to determine available margin: higher equity increases free margin, allowing more leveraged trading. If equity drops below the margin call threshold, brokers may issue a margin call, requiring the account holder to add more funds to their account or risk the position being closed automatically. Leverage amplifies this effect, increasing potential gains and losses, making equity crucial for managing risk and avoiding margin calls.
In Europe, general margin requirements are overseen by organizations like the European Securities and Market Authority, but brokers typically adjust their own requirements depending on factors such as asset class, position size and equity. Maintaining a sufficient account balance and positive account equity helps traders manage leverage more effectively.
Equity and used vs free margin
Margin level is measured as a percentage of equity to used margin. Used margin is the portion of equity allotted to open positions. Free margin, mentioned above, is the remaining equity available to enter new trades.
Margin Level = (Equity / Used Margin) x 100
For example, in both shares and forex trading, if account equity falls below the required margin level, the broker may close positions to restore balance, highlighting the importance of effective risk management and maintaining liquidity.
Why equity matters for risk management
Understanding equity can help traders make important risk management decisions. For example, equity helps traders determine how much risk they can take per trade, guiding their position sizing.
Risk-management trading strategies like stop-loss orders can help prevent excessive drawdowns and protect account equity levels. This account protection is crucial because healthy equity levels ensure traders avoid margin calls where they might be forced to liquidate positions due to insufficient margin.
Equity reflects the overall net worth of a trader’s account, influencing decisions about entering or exiting trades, adjusting leverage and maintaining open positions. Maintaining a positive forex account balance and monitoring equity in trading helps forex traders withstand market volatility.
