5 Tools — Master Guide

Your complete toolkit

Five AI-powered tools built for Fin Bro Finance. This guide covers what each tool does, how to use it step by step, and the pro tips that unlock full value.

01

AI Trade Debrief Engine

Analyze every trade. Build your edge.

Log any trade and Claude scores it across three dimensions — decision quality, execution, and process — then gives you a specific, actionable improvement for next time. After 3+ trades, the Patterns tab automatically detects behavioral tendencies in your trading.

How to use it

  • 1.Fill in ticker, strategy, entry/exit, P&L, and result
  • 2.Write your thesis in your own words — what made you take the trade?
  • 3.Describe what happened and how you managed it
  • 4.Click "Analyze Trade" — Claude scores and debriefs in seconds
  • 5.Click "Save to Edge Journal" to log it permanently
  • 6.After 3+ trades, visit the Patterns tab for behavioral insights

Pro tips

Write honest theses. The more specific your setup reasoning, the more precise the AI feedback.

Log losses too. The best edge growth comes from debriefing losing trades — that's where the patterns hide.

Decision score ≠ outcome. A 9/10 decision on a losing trade is still a win. Focus on process scores over time.

Read “next time” rules literally. Copy them into a sticky note. That's your trading rule for tomorrow.

02

Options P&L Calculator

Black-Scholes multi-leg position builder

Build any options position — up to 4 legs — and see exact P&L at expiration, full Greeks, and scenario analysis across price/IV/time changes. Presets included for iron condors, spreads, straddles.

How to use it

  • 1.Enter spot price, IV%, DTE, and risk-free rate
  • 2.Click a preset (Iron Condor recommended for SPX) or build legs manually
  • 3.Enter the premium you collected or paid per leg
  • 4.Read max profit, max loss, breakevens, and R:R in the summary
  • 5.Switch to Greeks tab to see delta/theta exposure
  • 6.Use Scenarios tab to stress-test against price moves and IV changes

Pro tips

SPX settings: Multiplier 100, DTE = 0 for 0DTE, IV = current VIX ÷ 1.1 as rough estimate.

Scenarios tab first. Always check what a 2% move does to your P&L before entering.

Theta sign matters. Negative theta = you're paying time decay. Positive = you're collecting it.

03

Position Sizing & Risk Calculator

Kelly criterion + Monte Carlo drawdown sim

Enter your account size, spread parameters, and win rate. Get exact contract count, max loss per trade, daily cap, expected value, and a full risk checklist. Kelly tab optimizes bet sizing mathematically. Monte Carlo tab simulates 500 paths of your strategy.

How to use it

  • 1.Enter your real account size — no ego, be accurate
  • 2.Select your strategy and enter spread width + premium
  • 3.Set max daily risk % (suggested: 2%) and per-trade risk % (suggested: 1%)
  • 4.Set your realistic win rate — not your best week, your average
  • 5.Check all 6 rules in the Risk Rules Checklist — all should pass
  • 6.Run Monte Carlo with your real numbers to see ruin probability

Pro tips

EV must be positive. If Expected Value is red, stop — you don't have edge at that sizing.

Half Kelly always. Full Kelly is mathematically optimal but emotionally impossible. Use Half Kelly for real trading.

Ruin < 5% is the goal. If Monte Carlo shows >10% ruin probability, reduce size or improve win rate first.

04

Community Leaderboard & Trade Tracker

Personal rankings, streaks, badges, and equity curves

Log your trades, see rankings sorted by P&L, earn streak badges, and track your equity curve and win rate over time. Data is stored privately in your own browser on this device — it is not shared between members.

How to use it

  • 1.Open the Community Leaderboard tool from the Community page
  • 2.Members go to "Log Trade" → enter their handle + trade details → submit
  • 3.Leaderboard auto-updates — sorted by total P&L with win rate per handle
  • 4.Members visit "My Stats" → enter their handle → see personal equity curve + badges
  • 5.Badges auto-award: Streak Master (3+ win streak), Grinder (10+ trades), Big Winner ($500+ trade), Precision (70%+ WR)

Heads up

Trades live in your browser only — clearing site data resets your log. A shared members-wide leaderboard is on the roadmap.

Community tip

Post weekly screenshots of the leaderboard in Discord to drive engagement and competition.

Gamification tip

Offer a monthly prize (free month, merch) for the top-ranked member to drive participation.

05

Pre-Market Briefing Bot

AI-generated morning briefs delivered to Discord at 8:30am

Two modes: (1) Manual generator — paste in market context and get a formatted Discord brief in seconds. (2) Automated bot — runs 24/7 on a server and posts to your Discord channel every trading morning at 8:30am automatically, no Zapier required.

Manual mode — how to use it

  • 1.Open the tool and fill in market context: SPX levels, VIX, catalysts, GEX regime
  • 2.Add overnight news and your community bias
  • 3.Click "Generate Briefing" — Claude writes the full brief in ~5 seconds
  • 4.Click "Copy for Discord" → paste directly into your channel
  • 5.Or "Preview in Discord" to see the formatted output before posting

Pro tips

Context = quality. The more market data you give it (VIX, GEX regime, specific levels), the sharper and more specific the brief.

Add your own read. Fill in the "Community Bias" field with your personal thesis — it gets woven into the trade theses.
