What it computes

Retracement and extension levels from a swing you define. The page states the equation, the units it expects and the rounding it applies, so the result can be reproduced by hand.

Where it sits in the chain

A calculator gives you a number. This one feeds the next: account to risk, risk to position size, position size to the trade, and the trade to expectancy, drawdown and risk of ruin.

Method

Costs, slippage and non-USD conversion are handled by their own calculators rather than folded in silently here.
