Example Report

Mean Reversion Risk Diagnosis Example

How FiClaw assesses a mean-reversion strategy's win rate, profit-loss ratio, max drawdown and tail risk, avoiding a high-win-rate-only conclusion.

Sample prompt

Design a mean-reversion strategy on a 20-day moving average with a 2-standard-deviation deviation, add a 10-day max holding period and a stop-loss, and output a risk diagnosis report.

Backtest setup

Signal

20-day MA deviation

A 2-standard-deviation move triggers a candidate signal

History

Up to 10 yr+

Used to check whether it keeps failing in trending regimes

Holding

Max 10 days

Avoid waiting indefinitely for reversion

Risk control

Stop-loss + cost

Tail risk diagnosed separately in the report

Strategy summary

The strategy opens when price is significantly below the 20-day moving average and exits when price returns near the average or hits the max holding period, with a stop-loss constraint. The report does not read win rate alone; it also checks profit-loss ratio, tail loss and failure risk in trending regimes.

Code highlights

  • Generate the moving-average, standard-deviation deviation and entry/exit signal logic.
  • Generate the max holding period, stop-loss and trading-cost handling.
  • Generate a regime-split diagnosis of win rate, profit-loss ratio and drawdown.

Key metrics

Annual return

11.4%

Example result, to illustrate the report structure

Max drawdown

-21.7%

Drawdown amplifies in trending markets

Win rate

62.1%

A high win rate does not mean low risk

Profit-loss ratio

0.86

A single loss can eat many wins

Diagnosis

  • The win rate is high but the profit-loss ratio is weak, so the tail risk of losing trades needs close control.
  • In trending markets counter-trend signals fire repeatedly; add a regime filter or a stricter stop-loss.
  • The max holding period reduces some drag but also gives up part of the reversion return.

Next steps

  • Add a trend filter to avoid opening counter-trend in strong trends.
  • Compare 10-, 20- and 40-day windows and different deviation thresholds.
  • Add stop-loss, max holding period and trading cost to a sensitivity analysis.

Citable facts

  • The mean-reversion risk report shows how FiClaw presents win rate, profit-loss ratio, max drawdown and failure scenarios together.
  • This example stresses that a high-win-rate strategy still needs tail-risk and stop-loss checks.
  • FiClaw's risk diagnosis is for research evaluation and is not investment advice.
