Order Types Reference

Complete reference for OANDA order types available through the FiveTwenty SDK.

OANDA Order Types

OANDA supports four primary order types, each designed for specific trading scenarios:

Market Orders

Definition: Execute immediately at the best available market price.

Characteristics:

  • Immediate execution (subject to liquidity)
  • No price guarantee - executes at current market price
  • Ideal for entering/exiting positions quickly
  • Cannot be cancelled once submitted

Use Cases: - Quick position entry when timing is critical - Emergency position exits - Market making operations - High-frequency trading strategies

Limit Orders

Definition: Execute only at a specified price or better.

Characteristics:

  • Price guarantee - will not execute at worse price
  • May not execute if price is not reached
  • Can be modified or cancelled before execution
  • Ideal for planning entry/exit points

Use Cases: - Buying at support levels - Selling at resistance levels - Planned position entries with price discipline - Scaling into/out of positions

Stop Orders

Definition: Become market orders when a specified trigger price is reached.

Characteristics:

  • Converts to market order when triggered
  • Used for breakout strategies or stop losses
  • No price guarantee after trigger
  • Triggers on bid/ask depending on direction

Market-If-Touched (MIT) Orders

Definition: Become market orders when price moves favorably to a specified level.

Characteristics:

  • Triggers when price touches specified level
  • Converts to market order for immediate execution
  • Used for mean reversion strategies
  • Opposite trigger logic to stop orders

Use Cases: - Taking profits at target levels - Mean reversion entries - Counter-trend trading - Automated profit-taking

Order Classification

Pending vs Immediate Orders

Immediate Orders:

  • Market orders
  • Execute right away at current market prices
  • Cannot be modified or cancelled once submitted

Pending Orders:

  • Limit, Stop, and MIT orders
  • Wait for specific conditions before execution
  • Can be modified, cancelled, or replaced while pending

Entry vs Exit Orders

Entry Orders:

  • Open new positions
  • Increase existing position size
  • Used for initial market participation

Exit Orders:

  • Close existing positions
  • Reduce position size
  • Used for profit-taking or loss limitation

Order Parameters

Essential Parameters

All orders require these fundamental parameters:

Time-In-Force Options

Control how long orders remain active:

  • GTC (Good Till Cancelled): Remains active until filled or cancelled
  • GTD (Good Till Date): Expires at specified date/time
  • FOK (Fill or Kill): Must fill completely or cancel immediately
  • IOC (Immediate or Cancel): Fill partial amount, cancel remainder

Order State Management

Order Lifecycle

Orders progress through predictable states:

  1. PENDING - Waiting for trigger conditions
  2. FILLED - Successfully executed
  3. CANCELLED - Manually cancelled or expired
  4. REJECTED - Failed validation or execution

Practical Order Selection

Market Conditions Guide

Trending Markets:

  • Use stop orders for breakout entries
  • Use trailing stops for trend following
  • Limit orders for counter-trend positions

Range-Bound Markets:

  • Use limit orders at support/resistance
  • Use MIT orders for profit-taking
  • Avoid stop orders (prone to whipsaws)

Volatile Markets:

  • Use market orders for quick execution
  • Wider stop levels to avoid noise
  • Consider FOK orders to ensure fills

Low Liquidity:

  • Prefer limit orders for price control
  • Use smaller position sizes
  • Monitor bid/ask spreads closely
