Position Limit Orders

live

Summary

Position Limit Orders plugin enables AMM-based limit orders implemented fully on-chain.
This implementation is based on the popular notion that a concentrated liquidity position outside the current price range is essentially a limit order.

Note, there are some important differences with existing off-chain solutions:

  • • Limit Orders are only supported for ‘Sell High’/’Buy Low’ direction relative to existing price;
  • • Order can be executed partially if price movement is too small;
  • • User funds are withdrawn when the order is placed;
  • • User has to trigger funds collection after the order has been executed;
  • • Limit Orders are not time restricted and order cancellation is manual;

This plugin also requires a dedicated UI to enable user interaction with Limit Order functionality. Algebra provides a reference implementation of such a UI.

Features

  • Custom UI: Plugin-related UI needs to be integrated with DEX frontend.
  • Fully On-Chain: Deep integration with CLAMM mechanics ensures low slippage, order execution guarantees and no delays.
  • Moderate gas overhead: Limit Order check takes 20K - 40K gas on each swap. Closing all limit orders in single tick takes 140K - 150K gas (regardless of # orders closed).
  • Extra fees: Initiator of Limit Order obtains small fee generated by limit order liquidity
