Limit Order Bot

WHAT IT DOES

Limit Order Bot helps you monitor limit orders and detect when they would be filled at current market prices. You provide the asset pair, order size, limit price, and direction (buy or sell), and the tool checks current market prices to determine if your limit order conditions are met. It displays the status of each order—filled, pending, or unknown—and highlights orders that are ready to execute. This is essential for traders who want to automate their trading strategy without writing code or monitoring charts constantly. It reads the current network chain ID from your wallet provider for context, but price checks are performed locally based on user-provided price feeds.

HOW TO USE

Connect your wallet using the "Connect" button (required for network context). Select the target network (Ethereum Mainnet, Sepolia, Polygon, BSC, Arbitrum, Optimism, and testnets are supported). Add limit orders with asset pair, trade size, limit price, and direction (buy/sell). Enter current market prices for each asset pair in the price feed section. Click "Check limit orders" — the tool will compare each order's limit price with the current price and display the status. The entire operation is read-only — no transactions are signed or sent.

TECHNICAL MECHANISM

The tool compares the limit price against the current market price for each asset pair. For buy orders, the order is filled when the current price is less than or equal to the limit price. For sell orders, the order is filled when the current price is greater than or equal to the limit price. The tool uses ethers.js v5.7.2 for network context but performs all price comparisons locally. Results are displayed with color-coded status indicators: green (filled), yellow (pending), and red (no price feed). The tool does not execute trades — it only monitors and reports.

WHAT IT CANNOT SEE

The tool cannot guarantee that orders will execute at the specified price due to slippage, gas fluctuations, or network congestion. It cannot execute trades automatically — only provides notifications and recommendations. It is limited by RPC provider availability and price feed freshness. It cannot place orders on centralized exchanges. It cannot handle complex order types like stop-loss or take-profit without additional logic. It cannot detect if the user has sufficient funds for the order. It cannot account for order book depth or liquidity.
