Forex Martingale Calculator
Build a loss-triggered forex lot progression from your own base lot, multiplier, stop distance and pip value. The calculator exposes every broker-step-rounded order, cumulative stopped-trade loss and the gross result if a later target is reached, without claiming that Martingale improves expectancy or guarantees recovery.
Enter the Martingale sequence
Each next row assumes the previous trade reached its entered stop. All monetary outputs use the same account-currency pip value supplied below.
First intended order volume in lots.
A value of 2 doubles raw lot volume; it does not guarantee cost-adjusted recovery.
Number of stopped-trade rows to display, including the base trade.
Use the same declared stop distance for every row in this simplified ladder.
Gross target distance divided by stop distance, before spread, commission and slippage.
Enter the broker- and account-currency-specific money value of one pip for 1.00 lot.
Read SYMBOL_VOLUME_STEP in the symbol specification; every raw lot is rounded down to this step.
Entered per-order check only; the engine flags but does not silently cap a larger row.
Use the same account currency as the entered pip value.

How the Martingale ladder is calculated
The first row uses the entered base lot. Every later raw lot multiplies the base by the entered multiplier raised to the number of prior losses. A multiplier of two creates the familiar doubling ladder, while a multiplier of one produces a fixed-lot comparison. The page does not label any multiplier safe, optimal or profitable.
Forex brokers accept volume on a symbol-specific grid. The calculator therefore shows both the exact geometric volume and a planning volume rounded down to the entered broker step. It also compares each rounded order with the entered maximum order lot. A flagged row remains visible so the user can see where the requested progression stops matching the declared specification.
The monetary stop loss for one row equals rounded lot multiplied by stop pips and entered pip value per 1.00 lot. Cumulative sequence loss is the sum of that row and every prior stopped trade. These trades are treated as sequentially closed positions, not as simultaneously open grid legs.
Gross target gain equals the current row’s stop-loss amount multiplied by the entered target-to-stop ratio. Net after target subtracts all earlier stopped-trade losses from that gross gain. Spread, commission, swap and slippage are excluded, so a positive displayed net amount is not a guaranteed executable recovery.
Starting equity is held fixed as a comparison base. The audit reports equity after cumulative stops and marks the first row where entered losses exceed that starting equity. It does not simulate changing margin requirements, stop-out order, balance protection, deposits or a broker closing positions before the arithmetic sequence completes.
Worked example from the audited fixture
The audited example starts with 0.10 lot, doubles after each loss for six steps, rounds down to 0.01 lot, uses a 25-pip stop, an entered pip value of 10 account-currency units per pip per 1.00 lot, a 1.5 target-to-stop ratio and 10,000 equity.
- The displayed lots are 0.10, 0.20, 0.40, 0.80, 1.60 and 3.20. Their individual stop-loss amounts are 25, 50, 100, 200, 400 and 800, producing cumulative losses of 25, 75, 175, 375, 775 and 1,575.
- After all six displayed stops, the arithmetic equity is 8,425 and the loss equals 15.75% of starting equity. If step six reaches its entered 1.5R target after the first five stops, its gross gain is 1,200 and the before-cost sequence net is 425; that number is a conditional scenario, not a recovery forecast.

How to interpret the result
- Start with the cumulative-loss column. A Martingale sequence can look small at the first row while later geometric orders dominate the total monetary exposure.
- Compare raw and rounded lots. Broker-step rounding can alter the textbook progression, particularly with a small base lot or a non-integer multiplier.
- A positive net-after-target row only states that one entered target amount exceeds prior displayed stop losses before costs. It says nothing about the probability of reaching that row or target.
- A negative net-after-target value means the entered multiplier, payoff ratio and rounding do not offset the earlier displayed losses at that step. Increasing the multiplier would also increase the next stop loss.
- The entered maximum-lot flag is a specification check, not permission to split one oversized order. Aggregate symbol-volume limits, margin and liquidity can bind earlier.
- Use the existing Risk of Ruin Explorer for a separate fixed-fraction probability model and the Losing Streak Probability Calculator for a binary finite-horizon run model. Neither is silently embedded here.
Assumptions and limits
- Every row uses one constant stop distance, pip value and target-to-stop ratio. Real symbols, conversions, volatility and broker charges can change between trades.
- The model assumes each prior trade is closed at its stop before the next order. It is not an averaging-down grid, basket, hedge, recovery-zone or simultaneous-position model.
- No win rate, independence assumption, return distribution, order timing, market regime, gap behavior, spread widening or execution rejection is modeled.
- Pip value must already be correct for the symbol, account currency and 1.00 lot. The page does not infer a universal contract size or fetch a live conversion rate.
- The maximum-lot field checks one order only. It does not verify aggregate directional volume, margin availability, leverage, free margin, stop-out thresholds or negative-balance protection.
- No lot size, multiplier, step count, stop, target, strategy, EA setting, recovery attempt, trade signal or broker is recommended.
Which position progression answers which question?
Martingale, Anti-Martingale and grid planning are not interchangeable. The first two model sequential closed trades with different outcome triggers. The grid models simultaneously filled price levels and one shared adverse stop. Setting a multiplier to one creates a useful fixed-volume comparison without publishing another overlapping route.
| Model | Size changes after | Position state | Primary audit | Shared stop |
|---|---|---|---|---|
| Martingale | After a stopped trade | Sequential closed trades | Cumulative stopped-trade loss | No |
| Anti-Martingale | After a target-hit trade | Sequential closed trades | Next-loss giveback | No |
| Forex grid | At entered price levels | Simultaneous filled basket | Shared-stop basket loss | Yes |
| Fixed lot | No multiplier | Depends on chosen workflow | Constant per-row volume | Not a separate route |
Frequently asked questions
- It generates a loss-triggered lot ladder from entered assumptions and shows each rounded order, stop-loss amount, cumulative sequence loss and conditional gross target result.
- No. A later gross target can exceed earlier displayed losses under some inputs, but costs, gaps, rejected orders, margin limits and the chance of reaching that target remain outside the arithmetic.
- Raw lot equals base lot multiplied by the entered multiplier raised to the number of prior losses. The displayed planning lot is rounded down to the entered broker volume step.
- MetaTrader symbols accept volume on a broker-defined step. Rounding down avoids silently increasing the raw requested volume, while both raw and normalized values remain visible.
- It is the sum of the displayed monetary stop loss for the current row and every earlier stopped trade in the entered sequential ladder.
- No. It does not reproduce broker leverage, free margin, liquidation order, stop-out thresholds, gaps or negative-balance protection.
- No. Martingale rows here are sequential closed trades after losses. The Forex Grid Calculator models simultaneously filled price-spaced entries and one shared stop.
- No. It audits only the numbers entered and gives no lot, multiplier, stop, target, strategy, EA setting, signal or trade recommendation.

Verify the broker constraints before using a progression
Check the symbol’s minimum lot, maximum lot, volume step, aggregate directional limit, pip or tick value, margin method and stop-out rules. The calculator uses only what you enter and cannot verify that every later order would be accepted.
