Risk

Position Size Calculator

Determine the maximum number of shares/contracts based on account size, risk %, and stop distance.

Account Size ($)

Risk Per Trade (%)

Entry Price

Stop Loss Price

Tip: use a real stop. If stop = entry, sizing becomes meaningless.

Metrics

Profit Factor Calculator

Profit factor = gross profit ÷ gross loss. Higher means stronger edge.

Gross Profit ($)

Gross Loss ($)

Risk

The largest percentage drop from a peak in account equity (peak → trough).

Peak Balance ($)

Lowest Balance ($)

Drawdown is a risk input for sizing. If you don’t track it, you’re guessing.

Probability

A practical check: how likely are you to blow up if risk is too high, even with a positive edge?

Win Rate (%)

Reward:Risk

Risk Per Trade (%)

If expectancy is negative, ruin approaches 100% over time regardless of “discipline.”

Sizing

Theoretical optimal fraction of capital to risk. Use fractional Kelly in practice.

Win Rate (%)

Avg Reward:Risk

Account Size ($)

Rule of thumb: use 1/4 to 1/2 Kelly if you use it at all.

Growth

Visualize the exponential power of consistent monthly returns. (This is math, not a promise.)
