Plan the trade

Before trading

Decide the trade and size it before you click buy or sell—targets, stops, and risk per trade should be explicit, not improvised.

Position Size

Turn your max loss per trade and stop distance into a concrete position size.

Right before entry, once your stop and risk budget are set.

Open calculator

Risk/Reward

Compare planned profit to planned loss so the setup pays for the risk you are taking.

While the trade is still an idea—before you commit size.

Open calculator

Pip Value

Know what one pip move costs or pays in account currency at your planned size.

Before FX entries, when you need dollar impact per pip at that size.

Open calculator

Profit

Sketch dollar outcomes at your planned targets and stops for this ticket.

When setting take-profit levels and checking if targets are realistic.

Open calculator

Margin

See how much margin this position will tie up at your broker settings.

Before sending the order, especially with leverage or multiple tickets.

Open calculator

ATR Size

Widen or tighten structure based on how volatile the market is right now.

When volatility shifts and you need stops that match current ranges.

Open calculator

Manage risk

During risk management

Stay inside your risk budget while trades and correlations stack—protect capital before a bad sequence becomes a crisis.

Drawdown

Track how deep live equity dips from a peak while you are still in the game.

When exposure is building or after a string of losses—you need a live read on stress.

Open calculator

Risk of Ruin

Stress whether your current risk per trade can survive a rough patch of outcomes.

Before raising size or when variance feels heavier than expected.

Open calculator

Portfolio Risk

Add up risk across open positions so correlated bets do not blow past your limit.

When you run more than one active idea or the same theme in several markets.

Open calculator

Margin

Watch free margin as positions age so you are not forced out by maintenance pressure.

While scaling in, holding overnight, or when the book gets crowded.

Open calculator

Measure your edge

Strategy validation

Test the system itself—using assumptions or backtest stats—to see if the rules deserve real capital before you go all-in.

Expectancy

Model average dollars per trade from assumed win rate, payoff, and costs.

When you are deciding if a rule set is theoretically worth trading.

Open calculator

Win Rate

Plug in expected win frequency against average win and loss to check the math.

While building or revising a system profile before live deployment.

Open calculator

Kelly

Translate modeled edge into a suggested risk fraction for growth versus safety.

After you have stable assumptions—before locking in default risk per trade.

Open calculator

Monte Carlo

Run many random paths from your assumptions to see drawdown and outcome spread.

When you need to see how fragile a strategy looks under different streaks.

Open calculator

Review Performance

After trading

Work from what actually happened in your account—closed trades and real equity—to tighten rules, habits, and risk for the next cycle.

Expectancy

Compute expectancy from real fills and outcomes, not guesses.

After a batch of closed trades—did this period actually add dollars per trade?

Open calculator

Win Rate

Measure how often you won versus lost with your live execution.

End of week or month—compare frequency to the payoff you are getting.

Open calculator

Drawdown

Measure the damage periods did to your equity curve in practice.

After a drawdown episode—how deep, how long, and how fast you recovered.

Open calculator

Risk of Ruin

Update survival odds using realized stats and your current risk settings.

After material losses or before you change default risk—will the account endure repeats?
