The simple 4-step process to build your own Claude AI trading assistant

Imagine having a personal trading assistant that tracks every trade you take, spots when you’re repeating old mistakes, and runs your daily review ritual automatically at the close. With Claude Code, that’s now possible even if you’ve never written a line of code.

This guide walks through a simple four-step workflow to build your own AI trading assistant and performance dashboard. The focus isn’t on copying someone else’s layout—it’s on learning a repeatable process you can use to build any trading tool you can imagine.

What You’re Actually Building

Before diving into the steps, it helps to be clear on what this assistant is.

You’re building a personal trading dashboard: a simple HTML webpage that lives on your computer. It shows your stats, trades, patterns, and notes in a way that’s tailored to your process—not a generic template. You’ll update it by talking to Claude Code, and it will refresh the HTML file for you.

Think of it as your own custom version of tools like TraderVue: a performance tracker, journal, and coach in one place, built around what matters most to your trading.

Step 1: Plan Mode – Design the Tool Before You Build It

The first step happens inside Claude’s desktop app, in a special area called Claude Code. Unlike regular chat, Claude Code can create and edit files, run code, and build small apps for you. But you don’t start by letting it edit anything—you start in Plan Mode.

In Plan Mode, Claude doesn’t touch any files. Instead, you and the model co-design an implementation plan: a clear, written spec for what you’re about to build. This saves a lot of time later by avoiding messy debugging and half-baked ideas.

How Plan Mode Works

In Claude Code, you toggle to Plan Mode so it cannot edit files yet. Then you give it a detailed prompt in plain English describing what you want. For example:

• You want a trading dashboard you’ll update daily with trades, best opportunities ("best ops"), and notes.
• You want it modeled loosely on existing performance dashboards (you can attach screenshots from tools like TraderVue or examples you’ve found online).
• You want it to act like a personalized "TraderVue" that tracks the specific patterns, problem behaviors, and stats that matter to you.
• You want Claude to ask you questions before deciding anything important.

One powerful trick is to explicitly ask Claude to use an "ask user questions" mode. Instead of you typing long replies, Claude will present multiple-choice style options in batches (for example, three or four questions at a time), and you just click your answers. This keeps token usage low and makes the planning process feel like an interactive questionnaire.

Key Decisions Claude Will Ask You About

During this planning phase, Claude will build up a structured plan by asking you questions like:

• Where should the dashboard live? For this workflow, you’ll typically choose a local HTML single-page app that you open in your browser.
• Where does your data live? For example, human-readable files like JSON or Markdown that are easy to version and inspect.
• How does data get into the dashboard? Options include automatically pulling from a broker or platform, manually typing in trades, or using a scheduled routine that asks you questions at the close.
• What is the dashboard for? You might choose historical review, performance coaching, pattern detection, or daily accountability—or all of the above.

It will also ask about your terminology and structure. For example, what "best ops" means for you, how you tag patterns, what you want your end-of-day routine to ask (trade write-ups, best opportunities, mistakes, goals, etc.).

As you answer, Claude continually updates an implementation plan file (usually a .md Markdown document). When it has enough information, it will tell you the plan is ready and ask if there’s anything else you want to add. Once you’re happy, you save that plan file. That’s the end of Step 1.

Step 2: Build Mode – Generate the Skeleton Dashboard

Now that you have a clear plan, it’s time to let Claude actually build something.

In Claude Code, you start a new session, turn off Plan Mode, and enable "accept edits." This is Build Mode—Claude is now allowed to create and modify files.

You then:

1. Add your implementation plan file to the session.
2. Tell Claude something like: "Here’s my implementation plan for a trading dashboard. Please build the skeleton according to this plan."

Claude will then generate the basic structure of your app: an HTML file (and likely some CSS and JavaScript) that implements the layout, tabs, and data structures described in the plan. You don’t have to write any code yourself—it handles that for you.

When it’s done, you’ll be able to open the HTML file in your browser and see a first version of your dashboard. It won’t be perfect or fully customized yet, but the architecture will be there: tabs, sections, charts, and placeholders for your data.

Step 3: Personalize – Turn It Into Your Trading Brain

Once the skeleton is built, the real fun starts. Step 3 is where you shape the dashboard around your own trading process.

You stay in Build Mode and talk to Claude about specific changes you want. You might:

• Add or remove tabs (for example, a "Tendencies" tab or a "Playbook" tab).
• Adjust charts (e.g., show grade accuracy percentages, cumulative P&L by grade, or win rate by setup).
• Change layout and styling to make the information easier to scan.
• Insert new stats or filters that your current tools don’t support.

Examples of Powerful Personalizations

Here are some concrete ideas that came out of this workflow:

1. Grade-Focused Performance View
If you grade your trades (A+, A, A−, B, etc.), you can have a tab that breaks down performance by grade. For example:

• Accuracy by grade (how often you graded trades correctly).
• P&L by grade on the x-axis, with accuracy percentages on the chart.
• Calendar views colored by grade to quickly see when you drifted from your best setups.

2. Tendencies and Problem Patterns
You can create a "Tendencies" page that surfaces recurring themes from your trade write-ups and journal entries. For instance:

• "No man’s land sizing" – taking too much size in low-conviction areas.
• "End-of-month B-cap" – over-grading or forcing B trades near the end of the month.
• "Wrong execution style" – repeatedly using the wrong order type or entry style for a setup.

Some tendencies you can explicitly tell Claude to track. Others it can discover by scanning your historical write-ups and looking for repeated phrases and patterns.

Each day, when you log trades and notes, you can have Claude generate a short "coach’s note" that references your known tendencies. For example: "Today you mentioned no man’s land sizing twice—this is a recurring issue to watch."

3. Playbook Integration
You can feed your existing playbook into the dashboard so each setup has:

• Rules and checks in favor.
• Typical risk parameters.
• Historical win rate and P&L.
• Links or references to example trades.

The dashboard can then tally how often you trade each play, how well they perform, and whether you’re following your own rules.

This same workflow is flexible enough to build other assistants too, not just trading dashboards. For a different but related example of building a custom AI assistant without coding, check out this no-code AI assistant tutorial.

Step 4: Make It Automatic With Routines

Once your dashboard looks and behaves the way you want, the last step is to make it part of your daily routine. Claude Code supports "routines"—scheduled workflows that run at specific times.

You can set up a routine to trigger at, say, 4:15 p.m. every trading day. At that time, Claude pops up and walks you through a short checklist, for example:

• What trades did you take today?
• What were the best opportunities (taken or missed)?
• Any notable mistakes or tendencies that showed up?
• Any journal notes you want to add?

You answer in natural language, and Claude updates your data files and regenerates the HTML dashboard behind the scenes. The next time you open the page, everything is up to date—no manual spreadsheet work, no copy-pasting into third-party tools.

Over time, you can also backfill older trades so your dashboard has enough history to show meaningful charts and pattern stats.

Ideas for Extending Your Assistant

Once you’re comfortable with this four-step workflow, you can use it to build much more than a performance tracker. A few possibilities traders have discussed include:

• A setup grading assistant that understands your playbook and helps you quickly score new opportunities based on historical examples.
• A catalyst and news tracker that maps events to your specific businesses and plays, rather than generic market noise.
• Intraday check-ins that remind you of key rules, risk limits, or known traps when you’re about to size up.

The key is to keep things simple and anchored to real trading decisions. The goal isn’t a flashy, complex system that feels impressive but doesn’t move your P&L. The goal is a focused assistant that makes it easier to do the right thing in simple but critical moments: entering, sizing, managing, and exiting your best setups.

The Core Takeaway: Master the Workflow, Not the Template

The real edge here isn’t the specific dashboard layout—it’s the workflow:

1. Plan Mode: Co-design a clear implementation plan with Claude before any code is written.
2. Build Mode (Skeleton): Feed in the plan and let Claude generate the basic app structure.
3. Personalize: Iterate on charts, tabs, stats, and logic until the tool reflects your actual process and tendencies.
4. Routines: Automate data collection and daily rituals so the assistant stays current with almost no friction.

Once you understand these four steps, you can use Claude Code to build almost any trading tool you can imagine—without needing a traditional coding background. All you need is clarity about your process, curiosity about what’s possible, and the willingness to iterate.
