Monte Carlo / Fixed risk

Fixed Risk Simulator

Run hundreds of trade sequences using the same statistical edge. Compare best, median and worst paths, estimate when a portfolio could fail, and test step-up turnover cycles.

Each run samples new wins and losses independently from the entered win rate.

Purpose

See the path, not just the average.

A fixed-risk system can have positive expectancy and still experience a damaging sequence of losses. This simulator tests many possible orderings so you can inspect survival, drawdown and time-to-target together.

Turnover mode keeps cash risk fixed within a cycle, then increases the risk base only after the selected growth target is reached. Real fills, costs, correlated losses and changing market conditions are not modelled.
01
Describe the trading edge

Enter win rate and realised reward:risk from a sufficiently large trade sample.

02
Choose how risk scales

Use fixed cash per cycle for turnover planning, or a fixed percentage of current equity for continuous compounding.

03
Read all three cases

The median is the central path; the P10 case shows a plausible poor sequence and the P90 case shows a favourable sequence.
