CALENDARS
CALCULATORS
Position size
How many shares (or contracts) to buy, given your account, entry, stop, and risk %.
Profit target
Entry + target → exact P&L for stocks, crypto, options, and futures.
Risk / reward
Entry, stop, target → R:R ratio and the win rate you need to break even.
Compounding
Starting capital, return rate, number of periods → final value and growth curve.
Expectancy
Win rate, average win, average loss → expected value per trade.
R-multiple
How many Rs (units of initial risk) a closed trade actually made or lost.
Drawdown recovery
A 50% drawdown needs a 100% gain to recover. See the full curve.
Kelly fraction
Optimal bet sizing: f* = W − (1 − W) / R. Most traders use a fraction of full Kelly.
CAGR
Compound annual growth rate between a starting and ending account value.
