Plain-English summary

Risk Simulation is TradingSimuLab's downside-path layer. It asks what the path could look like if a setup does not develop cleanly. The purpose is to give users a clearer research process without turning one model score into a promise or personalized instruction.

Short plain-English summary

Risk Simulation uses simulated future price paths to estimate expected return, probability of gain, downside risk, drawdown, tail-loss risk, scenario ranges, and risk-reward quality.

It is not a crystal ball. It is a structured way to think about uncertainty before excitement about a setup becomes too loud.

What this model is designed to answer

Risk Simulation is designed to answer: is the potential reward attractive enough compared with the simulated downside?

Many market readers focus on upside first. Risk Simulation forces the opposite order: downside paths, drawdown, tail loss, and reward-to-risk come before excitement.

  • Estimate simulated downside paths.
  • Compare potential reward with tail-loss risk.
  • Understand how often simulated paths finish positive.
  • Review expected return and expected price references.
  • See 5th and 95th percentile scenario bounds.
  • Compare average and worst simulated drawdowns.

Core Risk Simulation KPIs

KPIMeaningHow to read it
Expected returnCentral expected outcome from the simulation.It is not a guaranteed return. It is the simulation central estimate.
Expected priceConverts expected return into a price-level reference.It is a reference point, not a price target.
Probability of gainPercent of simulated paths finishing above the starting price.It is not a guarantee. It shows how frequently the simulation ended positive.
Horizon VaR 95%Severe downside threshold from the simulation distribution.VaR is a risk estimate, not a maximum possible loss.
CVaR 95% / Tail-loss riskAverage loss inside the worst simulated tail beyond VaR.CVaR often matters more than VaR because it describes the average severity of bad outcomes.
Average max drawdownAverage worst peak-to-trough decline across simulated paths.Shows the typical difficult path inside the simulation.
Worst max drawdownMost severe simulated peak-to-trough path.Useful for understanding extreme path risk.
Risk-Reward FactorCompares expected return against simulated downside risk.A weak or negative reading keeps the setup defensive.
RRF confidence rangeShows uncertainty around the Risk-Reward Factor.Wide ranges mean the reward-to-risk estimate is less stable.
5th percentile priceLower simulated scenario reference.It is not a forecast floor.
95th percentile priceUpper simulated scenario reference.It is not a price target.
Probability of large moveShows whether the simulation expects elevated outcome dispersion.High large-move probability means both upside and downside paths may be more active.

How to read the output

Start with tail risk before expected return. A positive expected return can still be unattractive if CVaR, drawdown, or Risk-Reward Factor are weak.

Next, compare probability of gain with price ranges. A high probability of gain can still come with large downside if the negative paths are severe.

What the model does not do

Risk Simulation does not predict the exact future path. It does not guarantee that losses will stay inside VaR or CVaR.

TradingSimuLab does not expose the internal simulation configuration or proprietary assumptions.

Example interpretation framework

Positive expected return, poor tail risk: the center of the distribution may look useful, but the bad tail remains too severe to ignore.

High probability of gain, weak risk-reward: many small positive paths can coexist with a few severe negative paths, so tail metrics matter.

Trend support, defensive simulation: trend quality can be constructive while simulated downside keeps the full read cautious.

How this model fits into the five-model stack

Risk Simulation is the can-the-downside-be-tolerated layer. Trend Detector checks current health. Trend Persistence checks durability. Timing Model checks breakout quality. Macro Model checks the 12-month backdrop.

FAQ

What is Monte Carlo risk simulation?

Monte Carlo simulation creates many possible future price paths to estimate outcome ranges, downside risk, drawdown, and reward-to-risk.

What is VaR?

VaR is a downside threshold from the simulation distribution. It is a risk estimate, not a maximum possible loss.

What is CVaR?

CVaR measures the average loss inside the worst simulated tail beyond VaR.

What is probability of gain?

Probability of gain shows how often simulated paths finished above the starting price.

Is Risk Simulation financial advice?

No. It is an educational research tool for understanding simulated uncertainty and downside-path risk.
