Risk warning CFDs are complex instruments. 74–89% of retail investor accounts lose money when trading CFDs.
Tools

Calculators that do the arithmetic, not the deciding.

Free, no sign-up. Results update as you type. Each tool links to the lesson that explains the idea behind it.

Position size

How many lots keep a loss at the stop to the share of the account you chose to risk.

POSITION SIZE
0.33 lots
Money at risk: 100.00. Lots are rounded down to 0.01.
Position size = money at risk ÷ (stop in pips × pip value per lot). A wider stop means a smaller position for the same risk. Module 9 — Risk management and capital protection →

Pip value

What one pip is worth for your position, converted into your account currency.

VALUE OF ONE PIP
10.00
For EUR/USD in a USD account the rate is 1. For USD/JPY in a USD account it is 1 ÷ the USD/JPY price.
Pip value = units × pip size × conversion rate. It changes with the exchange rate, so recalculate it before sizing each trade. Module 3 — Forex market →

Risk-reward

Compare what the trade risks to the stop with what it aims for at the target.

REWARD TO RISK
1 : 2.00
Break-even win rate at this ratio: 33.3%, before costs.
A ratio means nothing without the win rate: 1:2 needs to win more than one trade in three just to break even, and costs push that higher. Module 9 — Risk management and capital protection →

Drawdown recovery

The gain needed to get back to where you started after a loss.

GAIN NEEDED TO RECOVER
+25.0%
Because each gain is earned on a smaller balance.
Required gain = loss ÷ (1 − loss). A 50% loss needs a 100% gain, which is why limiting losses matters more than chasing returns. Module 0 — Before you trade →

Margin

How much of your balance the broker sets aside to open the position.

MARGIN REQUIRED
3,616.67
Position value: 108,500.00. A loss of 3.33% on that value would use up all of this margin.
Margin = units × rate ÷ leverage. Margin is a deposit, not the most you can lose: losses come out of the whole balance. Retail leverage is capped at 1:30 on major pairs in the UK, EU and Australia. Module 3 — Forex market →

Swap (overnight financing)

What holding the position overnight costs or pays, from the swap rate your broker quotes.

FINANCING FOR THE HOLD
−32.50
Per night: −6.50. A Monday-to-Friday hold usually counts 7 nights, because one night (often Wednesday) is charged three times for the weekend.
Swap = lots × 100,000 × point size × swap points × rate × nights. Rates differ for long and short positions and change with central bank rates. Swap-free (Islamic) accounts replace it with other fees. Module 3 — Forex market →

Pivot points

Classic floor-trader levels for today, from yesterday’s high, low and close.

LEVELS FOR TODAY
R3—
R2—
R1—
Pivot—
S1—
S2—
S3—
Pivot = (high + low + close) ÷ 3; R1 = 2 × pivot − low; S1 = 2 × pivot − high; R2 and S2 add or subtract the day’s range. Brokers set “yesterday” by their own daily close (often 22:00 GMT), so their levels can differ. Module 7 — Technical analysis →

Fibonacci retracement

Common retracement levels between a swing low and a swing high.

RETRACEMENT LEVELS
0%—
23.6%—
38.2%—
50%—
61.8%—
78.6%—
100%—
An up move retraces down from the high: level = high − (high − low) × ratio. A down move retraces up from the low. The levels mark where traders watch for a reaction; price respects them only some of the time. Module 7 — Technical analysis →

Risk of ruin

The chance that a run of losses takes the account down to a level you would call ruin.

CHANCE OF RUIN
—
Expectancy: — per trade. From 4,000 simulated sequences of trades with the same odds (the same inputs always give the same answer).
Raising risk per trade from 1% to 5% can turn a near-zero chance of ruin into a likely one, even with the same win rate and reward to risk. With negative expectancy, ruin is only a matter of time. Module 9 — Risk management and capital protection →

Compounding

How a balance grows when each period’s return is added to it, with regular deposits if you make them.

FINAL BALANCE
—
You put in —; returns added —.
Each period: balance = balance × (1 + return) + deposit. Steady returns like these are an assumption, not a forecast: real returns vary and can be negative, and a loss compounds too. Module 17 — Long-term investing vs active trading →
