⚠️ **Trading warning / Avertissement trading** : informational only, not investment advice. Position sizing is where accounts die: leverage multiplies losses as faithfully as gains, and martingale-style recovery, even capped, can turn a drawdown into a liquidation. This skill tests those models in backtests; no backtest makes a dangerous sizing model safe. Curated by Skill Harbor: a specialist persona prompt from DaviddTech's ai-trading-agent repo that works only on the capital allocation layer of a strategy that already has an edge. It is forbidden from touching entry signals, exit signals, indicator logic or regime filters; what it may tune is size, leverage, risk per trade, Kelly fraction, volatility-adjusted sizing, drawdown throttling, equity-curve scaling, maximum exposure and stop-trading conditions. It benchmarks a fixed-risk baseline, then tests fixed leverage (2x to 10x), fractional Kelly from 10% to 100% (with the explicit warning that full Kelly is never assumed safe), volatility-adjusted and drawdown-aware sizing, anti-martingale scaling, a controlled martingale recovery model with strict survival rules (bounded steps, max loss cap, liquidation checks, automatic shutdown; unlimited doubling and hidden blown tests are forbidden), and a hybrid model. Variants are backtested through the Trader Dev MCP tools and ranked by return-to-drawdown ratio, survival probability and liquidation safety before net profit. From the DaviddTech/ai-trading-agent repository (MIT). Honest caveats: it needs the third-party Trader Dev platform, it can only optimise a strategy that genuinely works (sizing cannot rescue a bad edge, it can only dress one up temporarily), and its own philosophy section admits the tension: it pushes hard on profitability while repeating that profit is irrelevant if the account dies. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseThe install prompt below already includes the vetting steps: your agent follows the community checklist before installing anything with executable code. Want more?
Use "Position Optimizer" with your Muse. Prerequisites: access to the Trader Dev MCP backtesting platform (a third-party service; check its current terms) and one strategy with a real, already measured edge to work on. This skill changes position sizing only, never the strategy logic, and it trades nothing live. 1. Open the skill: https://github.com/DaviddTech/ai-trading-agent/blob/main/skills/position-optimizer/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Take this strategy's baseline metrics, then test fractional Kelly, volatility-adjusted and drawdown-aware sizing against the fixed-risk baseline." 3. Read the risk analysis section before the profit numbers: return-to-drawdown change, largest losing streak, liquidation risk and risk of ruin decide whether a variant is kept. Tip: reject any variant whose improvement comes from leverage alone; the skill is designed to expose exactly that trick, so make it do so. Safety: a skill is plain-text instructions; it runs nothing by itself. Sizing models are tested in simulation; live leverage and recovery models can destroy an account. Informational only, not investment advice.
