The Final Tape
Monte Carlo position sizing simulates thousands of equity paths using your journal’s empirical win rate, payoff distribution, and risk-per-trade settings — showing drawdown tails and survival before you increase live size.
Stress-test size before the next drawdown — using win rate and payoff pulled from your completed trades inside The Final Tape.
Traders who want simulation grounded in their own edge, use R-based risk, and need drawdown and Kelly views tied to a living journal — not manual spreadsheet copies.
This page describes Monte Carlo position sizing as it works inside The Final Tape. Parameters come from completed trades on your active portfolio — you are not typing hypothetical 55% win rates into a random web form.
Thousands of simulated paths show worst-case drawdown, recovery time, and distribution of outcomes. You decide whether to size up, stay flat, or cut risk — with evidence from your tape.
Compare theoretical Kelly to fractional Kelly and simulation-tested optima in the same workspace. Textbook formulas miss streak structure; your history does not.
Run scenario analysis for improved win rate, adverse streaks, and horizon changes. See how sensitive your equity curve is before you change live size.
When you add completed trades, simulation inputs refresh. Sizing decisions stay tied to current edge — not a snapshot from six months ago.
Online calculators use numbers you type once. The Final Tape refreshes win rate and payoff as you log trades — so sizing reviews stay tied to present edge, including streak structure Monte Carlo captures better than naive formulas.
Using Monte Carlo output from a different account. Ignoring tail drawdown when mean path looks fine. Applying full Kelly from a noisy 30-trade sample.
These product modules run on your completed trades, one canonical tape, no spreadsheet re-entry.
Full guide: growth, drawdown, Kelly, scenarios, and simulation history.

Learn more →No. Simulation runs inside The Final Tape on your journal data. Inspect mode lets you explore the Monte Carlo module on example data before you upgrade.
Yes. Create a free account to inspect a fully populated, read-only environment. Every major module is visible — no credit card required. Upgrade when you are ready to journal your own trades.
More completed trades produce stabler distributions. The platform recommends sufficient history for meaningful runs; inspection shows how outputs look with sample data.
No. The Final Tape is a performance operating system for review, analytics, and simulation. You log or import completed trades; the platform does not connect to brokers for execution.
Simulation informs size; you still define max daily loss, max positions, and playbook rules. Monte Carlo shows what history implies — not what you must risk tomorrow.
