Order Types

Alpha Sec. supports a comprehensive suite of order types tailored for both retail users and advanced traders. All orders are processed by Alpha Sec.'s deterministic sequencer and settled on-chain, ensuring full transparency, verifiable execution, and sub-second responsiveness.

Basic Order Types​

  • Limit Order: A limit order allows users to specify the maximum price at which they are willing to buy or the minimum price at which they are willing to sell. It is placed in the orderbook and only executes if the market reaches the specified price or better, making it well-suited for price-sensitive execution.
  • Market Order: A market order executes instantly at the best available price in the orderbook. It prioritizes execution speed over price precision and is commonly used for time-critical trades where immediate fill is preferred.

Conditional & Time-Based Orders​

  • Stop-Limit: This order type converts into a limit order once the market reaches a predefined stop price. It offers traders control over both the trigger condition and the execution price.
  • Stop-Market: This order becomes a market order when the stop price is hit. While it guarantees execution after the trigger, the final execution price may vary with market conditions.
  • TP/SL (Take Profit / Stop Loss): These are conditional orders designed to close a position automatically when a specific profit or loss threshold is reached. They are commonly used in risk management and automated strategy execution.
  • GTC (Good-Til-Cancelled): By default, all orders on Alpha Sec. are set to GTC. These orders remain active in the orderbook until they are either fully filled or manually cancelled by the user.

Advanced Order Types (Coming Soon)​

  • Trailing Stop: A trailing stop order dynamically adjusts the stop price as the market moves in the trader's favor. If the price reverses by a set percentage, a market order is triggered to help capture profits while limiting downside risk.
  • OCO (One-Cancels-the-Other): OCO orders pair a limit order with a stop order. When one of the two is executed or cancelled, the other is automatically cancelled. This mechanism is useful for conditional entry and exit strategies.
  • TWAP (Time-Weighted Average Price): TWAP splits a large order into smaller slices and executes them at regular intervals over time. This method helps reduce market impact and slippage, making it a preferred option for institutional and algorithmic traders.
  • ALO (Add Liquidity Only / Post-Only): This order type ensures that the order adds liquidity to the market. If the order would match immediately upon placement, it is rejected. It is commonly used by market makers to guarantee Maker status and avoid taker fees.
  • IOC (Immediate or Cancel): An IOC order attempts to execute all or part of the order immediately. Any unfilled portion is cancelled without delay. This is suitable for time-sensitive trades where only immediate liquidity is desired.
