What-If Simulator — Grid Search

Episode 40 —

~6 min – the trading time machine that lets you rewind your exits, grid-search thousands of stop/target combinations on real historical trades, and watch heatmaps light up with the exact rules that would have printed the most R… without risking another dollar

You’ve already audited drawdowns, quantified costs, dissected streaks, ranked holding times, and watched your own tags indict you in Playbook Analysis. You’ve compared strategies head-to-head in Compare Charts.

Now open What-If Simulator (sidebar → Brain icon, route `/what-if-simulator`).

This is the page where the past becomes malleable. It takes your real completed trades for each setup, then brute-forces exit rules (stop-loss / take-profit grids) across hundreds or thousands of combinations — all on historical data — and shows you exactly which parameters would have maximized expectancy, win rate, profit factor, and R capture.

It’s not backtesting new entries. It’s exit optimization on trades you already took — a pure “what if I had managed this exit differently?” simulator.

Where to Find It

• Sidebar → What If Simulator (Brain icon)
• Direct route: `/what-if-simulator`
• Also reachable from CharterElite (e.g. PEE Analytics → Optimize button on a setup) or Council (Setup DNA → similar links)

Landing Page – Your Strategy Autopsy Waiting Room

Page header: “What-If Simulator – X strategies ready • Optimize your exit rules and maximize profits” (X = count of setups with hasData = enough completed trades)

Two Educational Accordions (expand these first):

1. Why What-If Simulator is Your Exit Strategy Optimizer

“Trading time machine” pitch: test stop/target combos on real past trades, see heatmaps of expectancy/R, find optimal rules, monthly ritual tip.

1. Complete Guide to Every What-If Simulator Feature

Strategy selection (Ready vs Needs More Trades), grid search (heatmap, results table), key terms (Stop-Loss, Take-Profit, Win Rate, Expectancy, R-Multiple, PEE Data), quick tips.

Search & Filter Bar

• Search: strategy name/description (case-insensitive)
• Status filter: All | Ready Only | Needs Trades

Strategy Cards Grid – The Launch Pad

One card per setup with ≥1 completed trade (sorted Ready first, then by completedTrades descending):

Ready strategies (hasData = true)

• Avatar + name + description
• Metrics: Completed Trades, Win Rate %, Total P&L $, Avg R-Multiple, Profit Factor, Max Drawdown %
• Badges: “Grid Search Ready” + “PEE Data Available” or “PEE Data Limited”
• Run What If Analysis button → `/what-if-simulator/strategy/:strategyId` (grid search page)

Needs more trades (!hasData)

• Same header
• “Insufficient Trade Data” message
• Progress bar (e.g. “X/10 Trades”)
• Badges: “X Trades” + “Analysis Pending”
• Disabled button: “Complete More Trades First”

Empty state (no setups with ≥1 completed trade): “No Trading Setups Found” + CTA to create setups (/settings/setups)

Ready Threshold

`completedTrades >= MIN_TRADES_FOR_ANALYSIS` (config, typically 10) PEE badge: “Available” if any trade has mfpe_price / mape_price / pee_data; “Limited” otherwise

Data Flow & Requirements

• Setups: `useSetups()` — all your saved setups
• Trades: `useTrades(limit WHAT_IF_INITIAL_TRADE_LIMIT e.g. 500, sort exit_date desc)` + `useCanonicalTradeMetrics(Completed, same limit)`
• Merged: canonical completed (net_pnl, realized_r, etc.) + original fields (PEE, prices) + active/missed from regular trades
• Per-setup stats: filter completed trades by setup_id or setup_name → compute trades, win rate, total PnL, avg R, profit factor, max DD, last trade date, PEE availability
• hasData: completedTrades ≥ MIN_TRADES_FOR_ANALYSIS

Quick Workflow – Exit Optimization Launch

1. Open What-If Simulator → expand accordions for context
2. Use Search + Ready Only to focus on analyzable setups
3. Scan cards:
   • High completedTrades + green metrics + “PEE Data Available”? → prime candidate
   • “Needs Trades”? → go close more setups there
4. Click Run What If Analysis on your best setup → grid search page:
   • Heatmaps of expectancy/R/win rate across stop/target grids
   • Results table: top combos by metric
   • Deploy button: copy optimal rule text into Setup settings
5. Repeat monthly: new trades → more data → sharper optimizations

Quick Reality Checks

• No cards? → No setups with ≥1 completed trade — close some trades
• All “Needs Trades”? → Most setups <10 completed — focus on tagging & completing
• “PEE Data Limited”? → Some trades missing MFPE/MAPE — fill in Execution Details
• No “Run” button? → Below threshold — close more trades on that setup
• Green metrics but no PEE? → Still useful for basic grid search, but exit sims weaker

Or open What-If Simulator right now. Filter Ready Only.

Pick your highest completedTrades + PEE Available setup.

Hit Run What If Analysis.

Watch the heatmaps light up with combinations that would have printed more R than you actually captured.

That’s your edge — hiding in the exits you already took.

Find it. Deploy it. Rewrite history forward.

Your next trades deserve those optimized rules.

Give them to them.

One grid search at a time.

The past is fixed. The future isn’t.

Optimize it. 😈
