Kalshi Bot Builder: Automate Trades Without Writing Code

Not a developer? No problem. You don't need to write a single line of code to run automated trading strategies on Kalshi. Our visual bot builder lets you create multi-step bots with conditions, triggers, and risk controls — all through a drag-and-drop interface.

This guide walks you through building your first no-code bot on Bot for Kalshi, from signing up to watching your first automated trade execute.

What is the Bot Builder?

The Bot for Kalshi bot builder is a visual tool that lets you create automated trading strategies as a series of steps. Each step has:

• A condition — when should this step execute? (immediately, when price crosses a threshold, when the previous order fills, etc.)
• An action — what should happen? (buy YES, sell NO, specific quantity, limit price, etc.)
• Risk controls — position limits, expiration times, and stop conditions

Steps chain together: when Step 1's condition is met, it executes and activates Step 2. This lets you build complex strategies without writing code.

How It Works

1. Connect your Kalshi API keys — we encrypt them with AES-256. They're never stored in plaintext.
2. Search for a market — browse Kalshi markets directly in our interface, or paste a ticker.
3. Build your steps — add conditions and actions visually. Set prices, quantities, and limits.
4. Start the bot — hit "Start" and the bot begins monitoring and executing. You can stop it anytime with one click.

Building Your First Bot (5 Minutes)

Let's build a simple bot that buys a contract when the price drops below a target:

Step 1: Create a New Bot

Click "New Bot" in the bot builder. Give it a name — something descriptive like "Lakers Game Buy-the-Dip".

Step 2: Find Your Market

Search for the market you want to trade. The search finds markets by keyword, team name, or ticker. Click the market to select it.

Step 3: Add Step 1 — The Entry

• Condition: "Price below" → set your target price (e.g., 35 cents)
• Action: Buy YES
• Quantity: 5 contracts
• Order type: Limit at 35 cents

Step 4: Add Step 2 — The Exit

• Condition: "On fill" (triggers when Step 1's order fills)
• Action: Sell YES (take profit)
• Quantity: 5 contracts
• Order type: Limit at 55 cents

Step 5: Start

Click "Start Bot." The bot is now live — it will monitor the market price and execute when your conditions are met. You can watch its progress in real-time on your dashboard.

Multi-Step Bots: Chaining Conditions

The real power is in multi-step chains. Here are the condition types available:

By combining these, you can build strategies like:

• Scale-in: Buy 2 contracts at 40¢, then 3 more at 35¢ if the price drops further
• Bracket: Buy at 40¢, then simultaneously set a take-profit at 60¢ and a stop-loss at 25¢
• Recurring: Run the same strategy every day, automatically resetting after completion

Connecting External Signals

Pro plan users can connect external data sources to trigger trades:

• Weather signals — trigger a trade when a temperature forecast exceeds a threshold
• Price signals — watch a Kalshi market price and trigger an action in a different market
• Keyword signals — monitor news or social media for specific keywords

This turns your bot from reactive (watching prices) to proactive (processing external data and acting before prices move).

Strategy Examples

Weather Fade Bot

When a weather market is priced significantly differently from the latest forecast model, buy the underpriced side. Set up: price_below condition watching for a discount vs. your assessed fair value, with an on_fill exit 15¢ above entry.

Sports Momentum Bot

Buy YES on a favorite when the price dips below a threshold pre-game (often happens during the "degen fade" period). Take profit if the price recovers to fair value or higher.

Recurring Daily Trader

Enable "Recurring" mode and the bot resets after completing all steps. Perfect for daily weather markets where you run the same strategy every day on the new market.

No-Code vs. Custom Code: When to Upgrade

The bot builder handles most strategies. Consider custom code when you need:

• Complex mathematical models (ML, custom statistics)
• Cross-platform arbitrage (trading Kalshi and Polymarket simultaneously)
• High-frequency strategies (sub-second execution)
• Custom data integrations beyond our built-in signals

For everything else — and for 80% of traders — the visual builder is faster, safer, and easier to maintain. Start here, and graduate to code only when you hit the builder's limits.
