01
Expectancy Calculator
Estimate the average result per trade in R-multiples. Positive expectancy means the sample has a mathematical edge before costs and slippage.
Trading Tools Lab
Turn trading risk into numbers before emotions take over.
Use this lab to estimate expectancy, drawdown recovery, risk pressure, and position size. The goal is not prediction. The goal is to make risk visible before a student places a trade.
Decision system
Four numbers every learner should know.
These tools make the invisible parts of trading concrete: edge, recovery, survival buffer, and correct size.
01Expectancy tells whether the method has mathematical pressure.
02Drawdown recovery shows how hard losses are to repair.
03Risk stress reveals when sizing is too aggressive.
04Position sizing translates the plan into shares, contracts, or units.
Live calculators
Use the lab before the trade.
All results are educational estimates. They are designed for study, review, and risk planning, not for trade signals or profit guarantees.
02
Drawdown Recovery
See the return required to recover from a drawdown. A 50% loss requires a 100% gain to break even, which is why capital protection comes first.
03
Risk Stress Test
Combine expectancy and risk per trade to estimate whether the strategy has a healthy survival buffer or is likely to fail under normal losing streaks.
04
Position Sizing
Convert account risk into a practical size estimate. Use the unit value that matches the asset: dollars per point, pip value, contract value, or coin value.
How students should use it
Start with position size, check drawdown tolerance, then compare the planned setup with expectancy. If the numbers are weak, the student practices instead of forcing a trade.
How professionals use it
Professionals treat these outputs as risk controls. They validate assumptions with a large sample, include transaction costs, and reduce size when drawdown pressure rises.
What this prevents
Oversizing, revenge trading, weak stop placement, unrealistic recovery resources, and confusing a profitable single trade with a repeatable system.
