Trade on math,
not on hope.
Free calculators that reveal the honest mathematical reality of your strategy — expectancy, risk of ruin, position sizing — plus education without the hype. The quant desk's tools, made readable.
Nine calculators that do the honest arithmetic for you
Strategy Reality Check
FLAGSHIPThe one that tells most strategies the truth: your win rate is not your edge.
Position Size Calculator
Turns "how many lots?" into arithmetic you can defend at 2am.
Risk of Ruin
A number most course-sellers would rather you never calculate.
Expectancy Calculator
If this number is negative, no position size can save you.
Drawdown Recovery
The asymmetry that quietly ends most trading accounts.
Compounding Calculator
Compounding is real. The screenshots on Instagram usually are not.
Challenge Pass Probability
Higher risk speeds up passing — and speeds up busting. Test before you pay the fee.
True Friction Calculator
Standard vs raw ECN — the math shows which actually costs less at your lot count.
Overnight Swap Drag
A 14-day hold can pay half its target back to the broker. See it before you enter.
It usually isn't bad luck. It's math they were never shown.
Three numbers explain most blown accounts. None of them are a secret — they're just quietly inconvenient for anyone selling a course.
of retail accounts lose money
Broker disclosures across regulated markets land here year after year. The house edge is real — but most of the damage is self-inflicted through sizing and expectancy.
a 50% win rate at 1:1 after costs
Coin-flip accuracy feels fine until you subtract spread and commission. Without a reward-to-risk edge, "winning half your trades" is a slow, confident bleed.
to recover a 50% drawdown
Losses and gains are not symmetric. Halve your account and you need to double what remains just to break even. This is why survival beats aggression.
