Trading Risk Lab

Trading Risk Lab is a web-based trading risk management platform engineered for traders who prioritize capital preservation and quantitative trade planning over entry signals and market timing. The platform provides a comprehensive suite of interactive calculators that model the downside of every trade before capital is exposed, addressing the root cause of retail trading losses: poor risk management and emotional decision-making. Core functionalities include position sizing, risk of ruin analysis, position planning, partial close modeling, multiple entry strategies, scenario analysis, and a trading journal for performance tracking. The platform is designed for retail traders, active day traders, prop firm traders, and anyone seeking data-driven risk decisions. Trading Risk Lab distinguishes itself by incorporating execution-aware variables such as fees, spreads, slippage, and funding costs into every calculation, delivering net PnL projections rather than gross estimates. The interface is built for speed, delivering results in under 100 milliseconds, with a clean, distraction-free workflow that prioritizes fast calculations and practical trading workflows. The platform offers both free and premium tools, ensuring accessibility for traders at all levels while maintaining a strict privacy-first policy with no data sold. By focusing on the mathematics of risk, drawdown, and survival, Trading Risk Lab empowers traders to move from guesswork to precise, validated decision-making.

Position and Risk Calculator

Plan a single trade with precise position sizing, stop-loss, and take-profit targets in multiple units. This calculator is leverage-aware, providing margin requirements and liquidation estimates. It models net PnL by incorporating fees, spread, slippage, and funding costs, and supports custom symbol presets and contract settings for diverse markets. Results can be copied to clipboard for rapid execution.

Partial Closes

Build a multi-take-profit ladder with partial closes using preset exit strategies for scalp, swing, or trend trading. This feature calculates net PnL, remaining risk, and execution costs at every step of the ladder. It provides a blended reward-to-risk ratio for the full ladder and per-close snapshots of risk, upside, and efficiency, all while modeling fees, spread, and slippage.

Problem Solvers

Solve for missing trade variables quickly by calculating take-profit from risk/reward ratio or net profit, stop-loss from max loss or ATR, position size from fixed or percentage risk or margin, and leverage from target liquidation price. All solvers use a unified cost model and include a Quick Finder tool with deep-linkable outputs that can be copied to clipboard.

Multiple Entries

Model layered entries with unlimited individual entry points, each with its own TP, SL, quantity, and leverage settings. The tool calculates weighted average entry, TP, and SL prices, along with initial margin and notional exposure. It provides per-entry snapshots, net profit/loss projections, R-multiple analysis, and a breakdown table with copy-on-click functionality.

Scenarios

Generate and compare dozens of trade outcomes simultaneously by varying stops, targets, and sizing. This feature supports both risk-based and quantity-based sizing in points mode or price mode. All scenarios include fees, spread, and slippage modeling for realistic net results. The output includes KPIs and best/worst scenario identification, with the ability to save runs and compare strategies.

Trading Journal

Track every trade, analyze performance, and identify patterns in your trading behavior. The journal integrates with the risk calculators to provide a complete feedback loop, allowing traders to review past decisions, measure execution quality, and refine their risk management approach over time.

Pre-Trade Risk Assessment for Retail Traders

A retail trader can use the Position and Risk Calculator to define their account size, set a fixed percentage risk (e.g., 2%), and input their entry, stop-loss, and take-profit prices. The platform instantly calculates the optimal position size, notional exposure, margin requirements, and net PnL after fees and slippage. This prevents overleveraging and ensures every trade aligns with the trader's risk tolerance before capital is committed.

Multi-Exit Strategy Planning for Active Traders

An active day trader can use the Partial Closes feature to design a take-profit ladder that scales out of a position at three different price levels. By selecting a swing preset, the trader sees the blended reward-to-risk ratio, remaining risk after each partial close, and net PnL including execution costs. This allows for disciplined profit-taking while reducing emotional decision-making during volatile market conditions.

Solving for Missing Trade Variables for Prop Firm Traders

A prop firm trader facing a specific maximum loss limit can use the Problem Solvers to quickly determine the exact stop-loss price that keeps the loss within their daily drawdown constraint. Alternatively, they can solve for the required position size to achieve a specific dollar profit target. The unified cost model ensures that fees and slippage are factored into the solution, providing a realistic and actionable output.

Strategy Comparison and Scenario Testing for Systematic Traders

A systematic trader can use the Scenarios feature to test a single trading setup across 20 different stop-loss and take-profit combinations. By comparing the net PnL, risk/reward ratios, and worst-case outcomes, the trader can identify the most robust parameter set for their strategy. The ability to save runs and compare strategies over time supports iterative optimization and data-driven decision-making.
