Direct answer: equity in forex
In forex, equity is the current value of your trading account after taking into account the results of open positions (open profit or loss) plus the cash balance effects those positions create. It is meant to reflect where the account stands right now, based on market movements and your existing trades.
In practical terms, equity is often treated as:
- Equity = Balance + Unrealized P/L where balance is the account value from closed activity, and unrealized P/L is the profit or loss on trades that are still open.
Explanation: how equity works in a mean reversion range context
When you analyze price behavior through a mean reversion range lens, you typically track how price may move back toward a reference area. Even then, equity is not a strategy signal; it is a mechanics concept that changes with price.
As soon as you open positions, your account starts showing:
- Unrealized profit or loss, driven by how far current market price is from your entry price.
- Used margin, which is margin reserved by the broker to support open trades.
Two related terms are commonly used to interpret equity:
- Free margin: what is available after reserving used margin. If free margin shrinks, it can become harder to open new trades.
- Margin level: a ratio that compares equity to used margin. Many platforms use this to determine how close the account is to margin constraints.
Because equity is built from open-trade valuation, it can rise or fall quickly in volatile conditions. That matters for any range-based approach: price movement affects open P/L first, and equity follows.
Example checks: what you should verify independently
Since definitions can vary slightly by platform, you can verify the concepts by checking what your broker/platform shows:
- Unrealized P/L: confirm that open trades contribute to the equity figure.
- Balance vs equity: observe that equity differs from balance while trades are open, and converges as positions are closed.
- Used margin and free margin: check whether the platform’s “free margin” decreases when you open additional positions.
- Margin level behavior: watch how margin level changes as equity changes, not as a forecast.
These checks let you confirm that “equity” on your specific platform behaves as an account snapshot based on current open-trade valuation.
Limitations and uncertainty (important)
- Equity is not a guaranteed profit measure. It is a snapshot that depends on current prices.
- Equity can change rapidly because unrealized P/L updates with market price movements.
- Platform formulas may differ in wording or implementation (for example, treatment of swaps, fees, or certain margin components), so you should rely on the platform’s displayed fields and definitions.
- No specific future outcome can be inferred from equity alone; it only describes the account’s current state given open trades.
If you want the most precise meaning, use your broker/platform’s definition of equity, used margin, free margin, and margin level, since those fields are what ultimately determine how equity is calculated and monitored.
