Losing streak simulator
Even good traders have losing streaks. See how much of the account each streak takes at your current risk.
With a win rate of 50%, there is a 55% chance that in 100 trades you see at least once 6 losses in a row ; that means about 5.9% drawdown you must accept in advance.
| Losses in a row | Drawdown | Gain needed to recover | Chance in 100 trades |
|---|---|---|---|
| 3 | 3% | 3.1% | 100% |
| 5 | 4.9% | 5.2% | 81% |
| 7 | 6.8% | 7.3% | 31.8% |
| 10 | 9.6% | 10.6% | 4.4% |
| 15 | 14% | 16.3% | 0.1% |
| 20 | 18.2% | 22.3% | 0% |

Teagle's suggestion: risk at most 1.25% per trade, so you have room for four losses even on your worst day. Compare prop firms on Teagle
The complete guide to the forex calculator and risk management
Most big losses in trading don't come from a wrong analysis; they come from a wrong position size. The Teagle trader's calculator is a forex and crypto calculator that, before you open a trade, tells you how many lots you can take with your balance and stop loss, how much you lose if the stop loss is hit, how much margin gets locked, and what each pip is worth. That means position size (lot) calculation, pip value calculation, margin calculation and profit and loss calculation, all in one form. If you're not yet comfortable with the concepts of pip and lot themselves, first read the article Understanding pips and lots ; this guide is about working hands-on with this tool.
What does the Teagle forex calculator calculate?
The page has two sections. The first is the "Trade Planner", which calculates all the numbers of a trade together. The second is "Money Management Tools", which answers bigger questions: how far a run of consecutive losses takes the account down, where the liquidation price is in crypto futures, and how much compound interest and swap come to.
The planner works for major and minor currency pairs, gold, silver, US oil, the three indices Dow Jones, Nasdaq and S&P, and Bitcoin (as a CFD). Calculations assume a USD account and use each symbol's standard specifications; for example, one pip in gold (XAU) is taken as a $0.1 price move.
How to use the Trade Planner
Inputs
- Symbol and direction: Choose the symbol and specify whether it's a buy or a sell.
- Entry price: The calculator doesn't read the price on its own. Take the live price from the box next to the field and enter it; the default price is only approximate.
- Balance and risk: Account balance in dollars and the risk of this trade, as a percentage of the balance or in dollars.
- Stop loss: As a price or as a distance in pips. Take profit is optional.
- Account leverage: From 1:1 to 1:1000.
- Conversion rate: For minor pairs such as EUR/GBP, the rate of the second currency to the dollar is needed to convert profit and loss back to dollars.
In the "Costs and symbol specifications" section you can also enter the spread, round-trip commission and the contract size of one lot. The contract size of indices and crypto differs between brokers, so it's best to read it from the symbol specifications in MetaTrader.
Results
The result card shows the allowed size in lots, mini lots and micro lots. Size is always rounded down in 0.01-lot steps so that the loss doesn't exceed your risk cap. Below that you'll find the loss at stop loss, profit at take profit, risk-to-reward ratio, minimum win rate to break even, required margin and its share of the balance, value per pip, and the cost of spread and commission. A price ladder also shows the entry, stop loss and take profit at their actual distances.
Warnings, sharing and calendar
The calculator warns you if a trade's risk exceeds 2% of the account, if the margin locks more than half the balance, if the potential profit is smaller than the potential loss, or if the stop loss is so close that costs eat a large share of it. If there's important news in the next 24 hours for the currencies of that symbol in the economic calendar , that is shown too. With "Copy trade summary" and "Copy link to this calculation" you can save the plan or send it to someone; all the numbers stay in the link.
A simple example: calculating position size with a stop loss
Suppose you have an account with a $2,000 balance and want to buy EUR/USD. The hypothetical entry price is 1.1000, you set the stop loss 25 pips below and the take profit 50 pips above, and you choose 1% risk.
- Risk amount: 1% of $2,000, i.e. $20.
- The pip value for one lot of EUR/USD is $10, so the loss per lot at the stop loss is $250.
- Allowed size: 20 divided by 250, i.e. 0.08 lots. The pip value for this size is $0.8.
- Profit at take profit is $40 and the risk-to-reward ratio is 1:2; that is, you only need to win a bit more than about one third of these trades to break even.
- The trade value is about $8,800, and with 1:100 leverage about $88 of margin is locked.
If you also enter spread and commission, the size comes out slightly lower, because these costs also count as part of the risk. The numbers are hypothetical and only illustrate the method.

Consecutive losses and prop firm mode
By entering the risk per trade and the win rate, you see a table showing how much each losing streak takes off the account, what profit is needed to recover it, and how likely it is to happen in 100 trades. In prop mode, by entering the daily loss limit, the maximum overall loss and the loss so far today, you see how many losing trades remain until you fail the challenge. If you're taking a challenge at one of the prop firms , this section prevents many needless failures.
Crypto futures
For USDT perpetual contracts with isolated margin, it uses the risk, entry, stop loss, leverage, maintenance margin rate and fees to calculate the position size, margin, liquidation price, and the highest leverage that keeps the stop loss ahead of liquidation.
Compound interest, drawdown and swap
The compound interest section shows account growth with a fixed return per period, a profit reinvestment percentage and periodic deposits, as a table and a chart; this is a scenario, not a forecast. The drawdown section calculates the account's current drawdown and the profit needed to recover, and the swap section calculates the cost or income of holding a position overnight based on size, swap rate and number of nights.
Risk management with a stop loss: common mistakes
- Size first, stop loss second: The right order is the reverse. The stop loss is where your analysis becomes invalid; calculate the size from that distance.
- Treating leverage as risk: Higher leverage only reduces margin and doesn't change the loss at the stop loss. For a deeper understanding, read margin in forex .
- Ignoring risk to reward: A low ratio means you need a high win rate. The article risk-to-reward ratio explains this relationship.
- Increasing size after a loss: The consecutive loss table shows why recovering from a big drawdown is harder than the drawdown itself.
For a more complete framework, see 10 key risk management standards in trading . This calculator is a calculation tool, not a buy or sell recommendation; check the contract size, minimum volume and swap rate in your own broker's symbol specifications before trading.
FAQ
How is position size (lot) calculated?
Position size equals the risk amount divided by the loss of one lot at the stop loss. For example, with $100 risk and a 50-pip stop loss on EURUSD, where each pip is worth $10 per lot, the size is 0.2 lots. If you enter the spread and commission, the size becomes slightly smaller.
What is the value of a pip in forex?
In currency pairs where the second currency is the dollar, each pip is worth $10 per standard lot. For other symbols, it depends on the contract size and the conversion rate of the second currency to the dollar, and the calculator works it out for your position size.
Why does it ask for a conversion rate for some currency pairs?
The profit and loss of each currency pair is calculated in its second currency. In EURGBP the second currency is the pound, so the GBPUSD rate is needed to convert to dollars. In pairs like USDJPY, the symbol's own price is enough.
How much is one pip in gold, indices and Bitcoin?
In this calculator, one pip in gold is $0.1, in silver and oil 0.01, and in indices and Bitcoin one price unit. Contract sizes for indices and crypto differ between brokers and can be changed in the symbol specifications section.
What is margin and how does leverage affect it?
Margin is the money the broker locks to keep a trade open, and it equals the trade value divided by leverage. Higher leverage reduces the margin, but it does not change the loss at the stop loss.
What is a good risk-to-reward ratio?
It depends on your win rate. With a 1:2 ratio, you only need to win more than one-third of your trades to break even; the calculator shows this minimum win rate for each trade.
How is the liquidation price calculated in crypto futures?
For isolated margin on USDT-margined contracts, for a long it is entry price × (1 − 1/leverage + maintenance margin rate), and for a short it is entry price × (1 + 1/leverage − maintenance margin rate). Exchanges' figures may differ slightly due to fees and margin tiers.
What percentage of my account should I risk per trade?
Most professional traders stick to 1 to 2 percent. The calculator warns above 2 percent and considers anything above 5 percent dangerous.
Results assume a dollar account and standard symbol specifications. Contract size, minimum volume and swap rates differ between brokers; check them in the symbol's details before you trade. This tool is not investment advice.
