The **Marketplace** is the community exchange for published Cortex agents. Open it from Cortex (`/cortex/marketplace`) after you log in to the web app.

Creators publish from [Agent Builder → Publish](https://tradeecho.com/docs/features/cortex/agent-builder#step-4-publish). Followers browse listings and subscribe in **paper** or, when eligible, **live auto-execute**.

## Marketplace tabs

The Marketplace has five tabs - same names as in the app:

| Tab | What it does |
|-----|----------------|
| **Browse agents** | Community listings with descriptions, tags, and performance snapshots |
| **Leaderboard** | Agents ranked by performance metrics |
| **My listings** | Agents **you** published to the community (creator view) |
| **Subscriptions** | Marketplace listing subscriptions **you** follow (follower view) |
| **Live dashboard** | Real broker fills and realized P&L from your **live** marketplace subscriptions |

### My listings vs My Agents

These are easy to confuse:

- **My Agents** (`/cortex/agents`) - every agent **you** built, private or public. See [My Agents and Approvals](https://tradeecho.com/docs/features/cortex/agents).
- **My listings** (Marketplace tab) - only **community-published** rows other members can subscribe to.

---

## Browse and evaluate

On **Browse agents**:

- Sort by top P&L, win rate, or subscriber count.
- Filter by category or tags.
- Open a listing detail page for full description, performance history, and subscribe controls.

Before you subscribe, review **sample size** and drawdown - not just a short hot streak. Paper and live results on the listing are the creator's agent track record, not a promise of your follower P&L.

---

## Subscribe to a listing

From a listing detail page (or agent modal), choose **paper** or **live** follow mode.

### Paper subscribe (all members)

- Follow the listing's strategy in **simulation** in your account.
- You see signals and paper-style performance tied to that subscription.
- **No real broker orders** are placed.
- Good for learning what an agent does before committing capital.

### Live auto-execute

Live auto-execute needs a **validated live broker connection**, a listing with **live execution enabled** for followers, and sizing / risk caps completed on subscribe. You **cannot** live-subscribe to your **own** agent (use paper to preview the member experience).

| Membership | Live Marketplace follows |
|------------|--------------------------|
| **Lifetime** | **Unlimited** live follows and own live agents, with a broker picked per agent |
| **Monthly / yearly** | **1 live** slot at a time, shared between a live Marketplace follow **and** your own live agent (mirrors the single-pilot Copy Trading model). It trades on your **active Copy Trading account**. Unfollow your other live agent or move your own live agent to Paper (Sim) before starting a new live follow. A paused live follow still holds the slot. Upgrade to Lifetime for unlimited live agents. |

When live subscribe succeeds, the agent's signals can route **real orders** to your linked broker within the caps you set. Paper subscribe stays available to **all** members with no live-follow limit.

### Sizing and caps (live subscribe)

Live subscriptions ask for follower-side controls, including:

| Setting | Purpose |
|---------|---------|
| **Fixed contracts** | Contracts per copied signal |
| **Fixed dollar** | Dollar budget per trade |
| **% of portfolio** | Scale to a percentage of your account value |
| **Max contracts per trade** | Hard ceiling on follower size |

Pilot-mirror modes (% of trader size, Mirror pilot %) are not available for Cortex agents - those apply to human Copy Trading pilots only.

Defaults are conservative (often **1 fixed contract**). Adjust caps to match your account and risk tolerance before you enable live.

### Partial profits on followed agents

When an agent has **Take partial profit** steps (see [Agent Builder → Exits](https://tradeecho.com/docs/features/cortex/agent-builder#exits)), your copy follows the same steps on **your** position size. A step sells that share of the contracts you opened, never your last contract until the steps add up to 100%. If you hold **1 contract**, it sells at the first step. When the agent closes the rest of its position, your copy closes fully.

### Manage subscriptions

Open the **Subscriptions** tab to:

- Expand a row and edit live broker binding, sizing, or caps
- Pause or cancel a subscription
- See whether each sub is **paper** or **live**

Paper subscriptions stay simple - no live broker controls.

---

## Live dashboard

The **Live dashboard** tab is for **live marketplace subscriptions only**.

It shows:

- Broker **fills** and **realized P&L** from agents you follow with live auto-execute
- Summary counts of active live subs

Paper signals on listing pages and your agent's paper book are **separate** from this dashboard. If you only paper-subscribe, this tab stays empty until you add a live subscription.

## For creators: publishing to the Marketplace

1. Build the agent in [Agent Builder](https://tradeecho.com/docs/features/cortex/agent-builder).
2. On **Publish**, choose **Community** visibility.
3. Add description, tags, and confirm the transparency panel.
4. After save, find the listing under **My listings**.

Community listings can enable **live execution for followers** when live marketplace subscribe is available on the platform. Followers still choose paper vs live on their side. Live follow always needs a validated broker; **Lifetime** members may hold unlimited live follows, while **monthly / yearly** members have **1 live** slot at a time, shared with their own live agent.

Republishing or editing a listing does not silently turn off live follower execution if it was already enabled - check the listing detail before you announce changes to subscribers.

## Common questions

**I subscribed in Agent Builder to a community agent card - why isn't it under Subscriptions?**

Agent Builder **community follow** on a config card is a separate lightweight follow (scan subscription). **Marketplace listing subscribe** is the full listing flow with paper/live modes and appears under **Subscriptions**.

**Why did my live order skip?**

Live follower orders pass through the same risk engine as copy trading - slippage, spread, sizing, and caps can skip an intent. Check **Subscriptions** settings (slippage tolerance, max dollars) and **Live dashboard** for fill history. Paper mode never places broker orders.

**Can I live-follow my own published agent?**

No. Subscribe to your own listing in **paper** to preview the member experience. To trade your own strategy live, enable **Live** on the agent in [Agent Builder](https://tradeecho.com/docs/features/cortex/agent-builder) (creator path).

**I'm on monthly - can I follow live?**

Yes. Monthly and yearly plans include **1 live** agent at a time, on your active Copy Trading account. That slot is shared: a live Marketplace follow **or** your own live agent, not both. For unlimited live agents, upgrade to Lifetime. Paper follows never use the live slot.

**Where do I change size, pause, or see fills?**

- **Subscriptions** - edit sizing, caps, pause, or cancel (changing the broker per agent is Lifetime; monthly and yearly live follows use your active Copy Trading account)
- **Listing page** - creator performance / sample size
- **Live dashboard** - your live broker fills and realized P&L
