A $1,000 security deposit does not mean that only $1,000 is exposed to the market. In our teaching model, a margin leverage of 30 allows for a position with a nominal value of $30,000. An adverse price change of 1% is equivalent to approximately $300 before cost: 1% of the position, but 30% of the tied margin. The share of the entire account depends on the account value.
The offered leverage is a condition of margin calculation. The leverage actually used is another quantity: position value divided by account value. An account with $10,000 and $30,000 exposure uses approximately leverage 3, even if the opening is margined with leverage 30.
The Six Account Terms
| Definitions | Teaching model | Significance |
|---|---|---|
| Balance / balance of accounts | Start-up capital minus costs already booked | Open market losses are not yet realised |
| Open profit/loss | Valuation of the remaining position | Changes with the price; do not subtract the spread again |
| Equity | Balance + open profit / loss | Current account value in the simplified account |
| Margin | Nominal value at entry/margin leverage | Amount reserved for the position |
| Free margin | Equity - Margin | Available buffer in the model |
| Margin Level | Equity / Margin × 100 | Ratio of the account value to the linked margin |
MetaTrader documents these account sizes and, in addition, possible loans, blocked amounts and commission treatment. These additional components are missing from the teaching account; real advertisements can therefore deviate.
[MARGIN-ACCOUNT]Same position or same margin: two different comparisons
Our own example: USD 110,000 in notional exposure requires approximately USD 3,666.67 in model margin at 30:1 leverage, or USD 1,100 at 100:1. The identical position loses USD 550 before costs following an adverse move of 0.5% in either case. Higher leverage reduces the collateral requirement, rather than the monetary impact of each price move.
A different comparison: someone consistently using USD 1,100 in margin can control USD 33,000 at 30:1 leverage or USD 110,000 at 100:1 in the same model. Price risk and position-dependent costs then increase. This changes position size; it does not provide cheaper execution. Compare Position Size and Fees
Margin Call, Stop-out and Stop Loss
A margin call here refers to the configured alert area of the account. This does not result in a guaranteed telephone warning or a reliable deadline for repayment. Account conditions and notification methods must be checked with the provider.
Stop-out refers to an intervention threshold for forced position closures. The brokerage contract determines technical implementation and order; in the case of multiple positions, one closing can release margin and alter further closings. Our account has exactly one position and calculates only the threshold position.
A stop loss, on the other hand, is an order for a position. It is neither the margin call nor the account’s stop-out rule. An ordinary stop does not guarantee a specific execution course. Managing positions and stops

What happens if the course goes down?
Each change calculates a new snapshot of the same hypothetical position. No order is sent. The examples require constant margin and symmetric quotes.
After a complete closure
The starting example step by step
Our own assumptions: $5,000 starting account balance, 1 lot with 100,000 units, medium price 1.1000, conversion 1, leverage 30, spread 1 pip, entry commission $3.50. One pip here is 0.0001 and has a monetary value of $10.
Immediately upon entry: Balance $4,996.50; Open valuation loss due to spread $10; Equity $4,986.50; Margin $3,666.67; Free Margin $1,319.83; Margin Level approximately 136%. The spread is included in the open valuation, the commission already booked.
After 200 adverse pips: open loss $2,010, equity $2,986.50, margin level around 81.45%. The exemplary warning threshold of 100% has been undershot, but the stop-out threshold of 50% has not yet been reached. Free margin can therefore be negative, while the model is still above the stop-out.
The calculated 50% limit is approximately −315.32 pips. A price gap of −550 pips skips them and yields −513.50 USD equity before additional exit commission. The later price moment recording does not prove that a real broker would have kept the position open until then.
50% is not a universal platform standard
ESMA described leverage limits by underlying asset for its retail CFD intervention in 2018, an account-related closure rule at 50 % of the minimum margin required and account-related negative balance protection. One or more open CFDs can be closed. This is a specific regulatory architecture, not a general feature of any MetaTrader installation.
[MARGIN-ESMA]The historic decision was temporary. For today's binding classification, national rules, contractual company, customer status and product must be checked. This article does not presuppose the then ESMA structure as worldwide or currently without exception applicable law. The computer values 100% / 50% are editable doctrine assumptions.
Negative balance protection shall be distinguished from timely closing. It guarantees neither the receipt of the deposited money nor an execution exactly at the threshold. The mathematical gap charge is not capped to zero in the model: a legal account correction, if necessary, is a separate process. Regulation and Consumer Protection
Why Real Accounts Can React Differently
MetaTrader documents different margin methods by instrument and account type, conversion and special treatment of opposing positions. A “position value/leverage” formula is therefore not a complete platform algorithm for every symbol.
[MARGIN-METHOD]Our model keeps margin at entry level; price movement and constant spread only change open valuation. Actual margin can change due to conversion, changed requirements, instrument logic or other positions. No relay margin, portfolio clearing, option risks, stock market variation margin or automatic partial smoothing positions are calculated.
All commissions are entered as total amounts for the registered position. Financing is an already booked net amount; positive values burden, negative values write well. A change in the lots does not automatically adjust these money inputs. The spread model is symmetrical and constant at entry and exit. Currency and USD conversion remain fixed.
The invoice remains open
Quantity = lots × contract units. Monetary value per price step = quantity × price step × conversion. Nominal value = Quantity × Entry-level average price × Conversion. Margin = nominal value / leverage.
Balance = starting account balance − entry commission − booked financing. Open result = direction × price movement × monetary value per step − full spread × monetary value per step. Direction: Long +1, Short −1. Equity = balance + open result.
Threshold movement = (threshold percentage / 100 × margin − balance + spread exposure) / (direction × monetary value per step). Without position, the threshold is omitted. For small long positions, the algebraic threshold may presuppose a non-positive price; this is outside our positive price model and is not an executable price forecast. After full closure: new account balance = equity − exit commission; margin zero. Do not subtract the spread again.
The computer evaluates the entered point without course history. It has no liquidation state and does not reopen a position after a gap: each input is an independent what-if scenario.
