Position Guards — Automated Stop-Loss and Take-Profit

Set probability thresholds on any Polymarket position and let Kuroko automatically exit your trade when the market moves against you or hits your target.

Position guards watch your open trades around the clock. You define a stop-loss and take-profit probability for a position, and Kuroko polls the live market price every 60 seconds. When a threshold is crossed, it fires an exit order through your connected wallet — no manual intervention needed. If you don’t have a wallet connected, it records a paper trade exit and notifies you instead.

Guards require a connected wallet to execute live orders. Without a wallet, a triggered guard will record a paper trade and display an alert in the terminal, but no real order will be submitted to Polymarket.

How guards work

Every active guard is evaluated against the current market probability on a 60-second cycle. The outcome depends on which threshold is crossed first:

Trigger	Action	Shares sold
Probability ≥ take-profit	SELL — lock in gains	40% of position
Probability ≤ stop-loss	REDUCE — limit downside	65% of position
Neither threshold crossed	HOLD — no action	—

When a guard fires, the exit order is routed through your connected wallet to Polymarket’s order book. The guard records the triggered action and timestamp so you can review what happened.

Guards poll every 60 seconds. A sudden spike that reverses within a 60-second window may still trigger a guard if the threshold is crossed at poll time. This is a polling-based system, not a real-time stream.

Setting a guard

1. Open the Guards panel

   Go to /portfolio. On desktop, the Guards panel is in the right column. On mobile, tap the Guards tab.

2. Click + Add Guard

   Click the + Add Guard button at the top of the panel to expand the creation form.

3. Select your market

   Type in the search box to find the market you hold a position in. Results show the current probability next to each market name. Click the market to select it.

4. Enter your position details

   Fill in the number of Shares you hold and your Entry Price in cents (1–99). These values determine how many shares are sold when a guard fires.

5. Set your thresholds

   Kuroko pre-fills sensible defaults based on the current market probability:

   • Take-profit — defaults to min(current probability + 10, 99)
   • Stop-loss — defaults to max(current probability − 10, 1)

   Adjust these to match your own risk tolerance. The stop-loss must be strictly less than the take-profit, or the guard will not save.

6. Save the guard

   Click Save Guard. The guard becomes active immediately and will be evaluated on the next 60-second poll.

Threshold validation

Kuroko validates your thresholds before saving:

• Stop-loss must be strictly less than take-profit
• Both values must be between 1 and 99 (inclusive)

If the values don’t pass validation, the panel shows an inline error and the guard is not saved.

Guard actions explained

SELL

Take-profit triggered. Sells 40% of your position at the current market probability. Keeps 60% in place to capture further upside if the market continues moving.

REDUCE

Stop-loss triggered. Sells 65% of your position. Cuts most of your exposure while retaining a small position in case the market reverses.

HOLD

No threshold crossed. The guard is active and monitoring, but no order is placed this cycle.

Setting guards via AI chat

You can create a guard without opening the Portfolio panel. In the AI chat at /, use natural language:

/guard set stop-loss at 30% on my Fed rate cut position

The AI will parse your intent and create the guard with the thresholds you specified. You can also describe it conversationally:

Set a take-profit at 80% and stop-loss at 45% on my Trump wins position

Use the AI chat to set multiple guards at once across different positions. Describe each one in plain language and the AI will handle the form-filling for you.

Managing active guards

Each guard card in the panel shows:

• The market question
• Your stop-loss and take-profit thresholds
• The current live probability (labeled Now X%)
• The current guard status: HOLD, SELL, or REDUCE
• An On / Off toggle to temporarily pause the guard without deleting it

Click ✕ on any guard card to permanently remove it.

Storage

Guards are stored in your browser’s localStorage under the key kuroko_position_guards. They persist across page reloads and navigation but are specific to the device and browser you’re using. Nothing is synced to a server.

What happens if my wallet disconnects while a guard is active?

The guard continues to evaluate on every 60-second poll. If a threshold is crossed while your wallet is disconnected, Kuroko records a paper trade exit and displays a notification in the terminal instead of submitting a live order. Reconnect your wallet and re-create the guard if you want future triggers to execute live orders.

Can I have multiple guards on the same market?

Yes. You can set more than one guard per market — for example, one with conservative thresholds and one more aggressive. Each guard is evaluated independently on every poll cycle. Be aware that multiple guards on the same position can trigger at the same time if the probability moves through both thresholds in a single 60-second window.

How are guards stored, and do they survive a page reload?

Guards are saved to your browser’s localStorage and survive page reloads, tab closes, and navigation between pages. They are not stored on a server, so they are tied to the specific browser and device where you created them. Clearing your browser data or switching devices will remove your guards.
