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% |

Enter your prop challenge's rules to see how many losing trades you are from failing. Most props count losses against the starting balance.

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
Risk management in three steps
Set the risk first
Before you look at profit, decide the most of your account you'll lose on this trade; most professional traders use 1 to 2 percent.
Place the stop loss from the chart
The stop loss is where your analysis is proven wrong, not where the loss looks small. Size the position from that distance, not the other way round.
Let the calculator give the size
With the risk and the stop loss, the allowed size follows. If the size gets very small, the stop loss is too far for this account.
FAQ
How is the trade size (lots) calculated?
Size = risk amount ÷ (stop-loss distance × value of one price unit for one lot). For example, with $100 risk and a 50-pip stop on EUR/USD, where a pip is worth $10 per lot, the size is 0.2 lots. If you enter spread and commission, they are taken off the size.
Why do some symbols need a conversion rate?
Profit and loss of a currency pair are counted in its second currency. In EUR/GBP the second currency is the pound, so GBP/USD is needed to convert to dollars. In pairs like USD/JPY the symbol's own price is enough and no extra field is needed.
How much is a pip in gold, indices and crypto?
In this calculator a pip is $0.1 in gold, 0.01 in silver, 0.01 in oil, and one price unit in indices and bitcoin. Contract sizes for indices and crypto differ between brokers and can be changed under «Symbol details».
What is margin and what does leverage do?
Margin is the money the broker locks to keep a trade open: the trade's value divided by the leverage. Higher leverage lowers the margin but does not change the loss at the stop; size and stop loss decide the risk.
What is a good risk-to-reward?
It depends on your win rate. With a 1:2 risk-to-reward, winning more than 33% of trades is enough to break even. The calculator shows the «minimum win rate to break even» for each trade.
How is the liquidation price calculated in futures?
For isolated margin on USDT contracts: long = entry price × (1 − 1/leverage + maintenance margin rate), short = entry price × (1 + 1/leverage − maintenance margin rate). Each exchange's figure may differ slightly because of fees and margin tiers.
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.
