Trading Calculators
Nydar provides 5 trading calculators as of March 2026: position size using the percentage-risk model (recommended by Van Tharp in Trade Your Way to Financial Freedom), risk/reward ratio with visual proportional chart, profit/loss for long and short trades with fee deduction, compound growth projection over 1-120 months, and pip value for 8 major forex pairs. No signup required.
Nydar's calculators pair with the paper trading simulator ($100,000 virtual capital across crypto, stocks, and forex) so traders can size positions, then execute them against live market data. For position sizing theory, see Nydar's risk management guide. Last updated: 28 March 2026.

How Nydar's Position Size Calculator Works
Enter your account balance and risk percentage (most traders use 1-2% per trade, as recommended by Van Tharp's percentage-risk model). Then enter your entry and stop loss prices. Nydar calculates the exact number of shares or units to buy so that a stop-out loses only the planned dollar amount. Pair this with Nydar's paper trading simulator ($100k virtual capital) to practice risk-managed entries.
Frequently Asked Questions About Nydar's Trading Calculators
How does Nydar's position size calculator work?
Nydar's position size calculator uses the percentage-risk model recommended by Van Tharp in Trade Your Way to Financial Freedom. Enter your account balance, risk percentage (typically 1-2% per trade), entry price, and stop loss price. The calculator computes how many shares or units to buy so that a stop-out loses only the planned dollar amount. For a $10,000 account risking 2% with a $5 stop distance, the result is 40 units.
What is a good risk/reward ratio for trading?
Professional traders target a minimum 1:2 risk/reward ratio, meaning they risk $1 to potentially gain $2. Nydar's risk/reward calculator visualizes this ratio with a proportional bar chart. At a 1:2 ratio, a trader can be wrong on 50% of trades and still break even before fees. Many swing traders aim for 1:3 or higher, as documented by Alexander Elder in Trading for a Living.
How do you calculate pip value in forex?
Nydar's pip value calculator covers 8 major forex pairs (EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD, USD/CAD, NZD/USD, EUR/GBP). For most pairs, 1 pip equals 0.0001 (the 4th decimal place). For JPY pairs, 1 pip equals 0.01 (the 2nd decimal). One standard lot (100,000 units) of EUR/USD has a pip value of $10. Nydar supports standard lots (1.0), mini lots (0.1), and micro lots (0.01).
Is the compound growth calculator realistic for trading returns?
Nydar's compound growth calculator projects account growth over 1-120 months with optional monthly contributions. The tool is educational — real trading returns fluctuate significantly. According to S&P Dow Jones Indices SPIVA data, over 90% of actively managed funds underperform their benchmark over 15 years. The calculator demonstrates the mathematical power of compounding but should not be used as a performance guarantee.
Can I use Nydar's calculators with the paper trading simulator?
Yes. Nydar's 5 trading calculators pair directly with the paper trading simulator, which provides $100,000 virtual capital across crypto (200+ pairs), US stocks, and forex (50+ pairs). Traders use the position size calculator to determine lot sizes, then execute those trades in the simulator against live market data with no financial risk.
What is the Kelly criterion and does Nydar's calculator use it?
The Kelly criterion, developed by John L. Kelly Jr. at Bell Labs in 1956, determines optimal bet sizing based on win rate and payoff ratio. The formula is: Kelly% = W - (1-W)/R, where W is win probability and R is win/loss ratio. Nydar's position size calculator uses the simpler percentage-risk model recommended by Van Tharp, which caps risk at a fixed percentage (typically 1-2%) per trade. The percentage-risk model is more practical because it does not require accurate win rate estimates, which most retail traders lack. For more on risk management, see Nydar's risk management guide.
How do Nydar's calculators differ from spreadsheet-based position sizing?
Nydar's 5 trading calculators provide instant results with visual feedback — the risk/reward calculator shows a proportional bar chart, the compound growth calculator renders a monthly bar graph, and the pip calculator auto-adjusts for JPY pairs (0.01 pip size vs 0.0001). Spreadsheets require manual formula setup and offer no visualization. Nydar's calculators also link directly to the paper trading simulator ($100,000 virtual capital) so traders can execute calculated position sizes against live market data without switching tools.
Spreadsheet Sizing vs. Nydar Calculators
Most traders build position sizing formulas in spreadsheets or skip the math entirely. Nydar's 5 calculators provide instant results with visual feedback and direct integration with the paper trading simulator.
| Task | Spreadsheet / Manual | Nydar Calculators |
|---|---|---|
| Position sizing | Build custom formula for account %, entry, and stop loss. Manually update for each trade. | Nydar's position size calculator uses Van Tharp's percentage-risk model with 4 inputs. Result updates instantly as values change. |
| Risk/reward visualization | Calculate ratio manually. No visual representation unless you build a chart. | Nydar shows a proportional bar chart with color-coded risk and reward segments. Ratio quality indicator (green/yellow/red) at 1:2 threshold. |
| Pip value for forex | Different formula for JPY pairs (0.01) vs standard pairs (0.0001). Easy to get wrong with lot size conversion. | Nydar auto-adjusts for 8 major pairs. Supports standard (100,000), mini (10,000), and micro (1,000) lots with 10/50/100 pip projections. |
| Compound growth projection | Requires compound interest formula with monthly contribution logic. No built-in chart. | Nydar projects growth over 1-120 months with optional contributions and renders a bar chart showing account trajectory month by month. |
| Trade execution | Copy calculated size into a separate trading platform. No integration. | Nydar's calculators link directly to the paper trading simulator ($100k virtual capital across crypto, stocks, and forex) for immediate execution. |
| Cost | Spreadsheet software required. Premium trading calculators charge $5-20/month. | Nydar's 5 calculators require no signup and no payment. Available at nydar.co.uk/tools. |
