Short answer: balance vs equity in trading comes down to timing. Balance is the cash in your account after every closed trade has been booked. Equity is balance plus or minus the floating profit or loss on every open position, so it moves tick by tick while balance sits still. Watch equity for risk decisions and margin, and use balance for bookkeeping and closed results. A wide gap between the two means you are carrying a large or lopsided open exposure.
Quick comparison answer
Most traders watch balance because it is the tidy, stable figure. In my experience that is the wrong habit. Every rule that can hurt you, from margin calls to a prop-firm daily loss limit, is checked against equity.
- Balance answers: what have I actually kept?
- Equity answers: what is the account worth if everything closed this second?
Side-by-side comparison table
| Question | Balance | Equity |
|---|---|---|
| What it counts | Deposits, withdrawals, closed trade results | Balance plus floating profit or loss on open trades |
| How often it moves | Only when a trade closes or money moves | Every price tick while a position is open |
| What it drives | Statements, records, reward calculations | Margin level, margin calls, stop-outs, drawdown checks |
| Typical mistake | Treating it as available risk capital | Ignoring it until a warning appears |
A trader who plans size from balance while holding a losing open position is planning from a stale number.
What balance measures and how it moves
Balance is a ledger. It includes deposits, withdrawals and the realised profit or loss of each closed trade. Swap charges and commissions post to it as they are booked. Hold a trade for a week and balance stays unremarkable, however violently the market moves. That stillness makes it honest for record keeping and useless for live risk management.
What equity measures and how it is calculated
Equity is balance plus the current value of everything open, so the formula is plain: equity = balance + floating profit - floating loss. Trading platforms run real-time equity calculations on every quote, which is why the figure looks jittery during news. The CFTC glossary of trading terms (order types, margin, equity) is a useful reference for how equity, margin and related order terms are defined in general.
Equity feeds three derived numbers:
- Used margin, the collateral locked by open positions.
- Free margin, equity minus used margin.
- Margin level, equity divided by used margin, as a percentage.
When margin level falls to the broker's threshold, you get one of the margin calls described in our guide to what a margin call is. Balance plays no part in that check.
Decision criteria
Pick the number by the job in front of you.
- Sizing a new trade: use equity. A floating loss means your real risk capital is smaller than balance suggests.
- Judging a strategy over a month: use balance, because closed results are the only final ones.
- Checking a daily loss limit: use equity, since most rule sets measure it that way.
- Adding to a winner: use free margin, or you will squander the buffer that keeps you in the trade.
When to choose each option
Choose balance when the account is flat or when you are reviewing history. It is punctual, rarely disputed, and easy to compare across weeks. Choose equity whenever there is an open position, especially a large one relative to the account. Roughly speaking, once equity sits more than 2 percent away from balance, planning from balance is precarious and equity is the only number worth quoting. Higher leverage widens that gap faster, as our explainer on how leverage works in trading shows.
Worked example: one account, three snapshots
Start with a 10,000 balance, no open positions, so equity is also 10,000. Now open one EURUSD position at 1 lot, roughly 10 per pip, with a 50-pip stop.
- Snapshot one, price drops 30 pips: floating loss 300. Balance 10,000, equity 9,700.
- Snapshot two, price recovers and rises 40 pips: floating profit 400. Balance still 10,000, equity 10,400. Nothing has been earned yet.
- Snapshot three, you close at plus 40 pips: profit 400 books. Balance 10,400, equity 10,400, and the two numbers meet again.
Now the consequential part. Suppose at snapshot one you had opened a second lot because "balance was untouched". Used margin doubles, free margin halves, and a further 50-pip drop produces a 1,000 floating loss instead of 500. That is how an ordinary retracement becomes a margin call: the trader read balance, the platform read equity.
Tradeoffs and caveats
- Equity is truthful but noisy. Watching it during a spike makes traders skittish and invites clumsy exits.
- Balance is calm but stale. It hides drawdown until the trade closes, which is forgiving of your nerves and unforgiving of your plan.
- Spread and commission cost sits in both. A new position starts slightly below balance before the market moves.
- Some rule sets measure drawdown from the higher of balance or equity. That removes ambiguity but bites sooner, and swaps can quietly lower both in a lumpy way.
Equity and prop-firm drawdown limits
Prop-firm rules are where the distinction stops being academic. A daily loss limit measured on equity can be breached by a floating loss alone. A static total drawdown, the kind Pivex publishes before you start an attempt, is a fixed floor that equity is compared against. Trading account management in an evaluation is therefore mostly equity discipline. Our guide to trading within drawdown limits turns that into a daily routine. Pivex also runs a built-in assistant that tracks your limits against live equity, which removes the tedious mental arithmetic during a fast market.
Next step: open your platform, note balance and equity side by side, and write down the gap before your next trade. If you are preparing for an evaluation, repeat that against the daily and total limits, since Pivex checks both against equity, never the tidy balance figure.
