Active Orders

Manage your orders in the Order Status panel and Orders with the following tools:

  • SUSPEND/RESUME: A suspended order is not matched with incoming rates and other market participants cannot see it.

    Suspended orders expire according to their time in force. For example, suspended day orders still expire at the end of the trading day. Only GTC orders can remain suspended indefinitely.

  • FILL @ MKT: Quickly fill the open amount of any unfilled stop or limit order. Neon FX submits the remaining balance as a market order.

  • OFF: Cancel the order.

  • OFF ALL: Cancel all orders.

Order types

  • LMT: Matched at the limit price or better.

  • MKT: Matched immediately by sweeping the book.

  • STOP: Starts executing when the top of book breaches the order's trigger rate. The order is then executed as a market order.

Where to find the settings menu

Choose Settings at the top left of the toolbar to access settings.


Display: Date, time, and amount display preferences.

P/L currency: Choose the P/L currency for positions.

Disable automatic unit shortcuts: Apply units to amounts of four or less whole numbers to protect you from entering inadvertently large amounts.

Show prices for maximum size available: Show prices for the maximum size currently available in the market or only for your requested size. If there are no prices greater than or equal to your requested size, Neon FX shows empty prices.

Show dealt currency direction on trading panels: Show the dealt currency with the SELL/BUY indicators in ESP trading panels.


Trading Style: Take prices with a single click or double click. Some traders prefer the convenience of a single click while others prefer the security of a double click. Regardless of the setting you choose, Neon FX adds a one second delay after you take a price to protect you from accidentally executing multiple trades.

Confirm order submission: Require additional confirmation with a pop-up window when taking ESP prices from the Board, Full Book, and Ladder panels and submitting orders from the Order Entry panel.

Confirm RFS Trade Submission: Require additional confirmation with a pop-up window when taking prices from the RFS Spot/Outright and RFS Swap panels.

Confirm Pre-trade Allocation (PTA) Submission: Require additional confirmation with a pop-up window when submitting pre-trade allocations.

Volatile Market Multiplier: During times of increased market volatility, execution ranges that are effective in normal market conditions are too narrow and the orders you place may go unfilled. Use the Volatile Market slider switch in the Settings menu bar to quickly increase the execution range of your market range orders to better ensure that your liquidity needs are met. You define the volatile market factor with the Volatile Market Multiplier field in the Trading settings window (Settings > Trading).

To toggle volatile market trading on and off, choose the Volatile Market slider button in the Settings menu bar. When the slider is ON, the execution ranges that you have defined are multiplied by the Volatile Market Multiplier value.

Rows to display in Full Book: Set the number of rows of prices in the Full Book panel. The number must be between 1 and 12. When you specify 6 or more rows, a scrollbar appears so that you can scroll through all prices in the panel.

Maximum notional amount: You can define a maximum size for the prices you take and orders you place. The maximum size limits your potential exposure to inadvertently trading too large a size. In the trading panels, if you enter an amount that exceeds the maximum size, Neon FX alerts you with an override button and disables trading in the currency. Choose the override button to continue. When you trade the term currency, the maximum size is converted using the market midrate.

Execution Range:
  • Range: For each currency pair, define a range of pips by notional size that you are willing to accept to ensure immediate execution. Neon FX matches your orders according to that range:
  • Range greater than zero: Your orders are matched against market prices within that range from the top of the book.
  • Range of zero: Your orders are matched as a limit order using the price you take as the limit price.
  • Fill at MKT Range: Define a range of pips for market orders submitted when you choose the Fill @ Mkt button in the Order Status panel Neon FX uses the fill-at-market range when filling TWAP orders when they expire. This range is separate from the default range that you set for market orders, allowing you to set a wider range for immediate execution of fill-at-market orders.
  • Expiry Define the number of seconds your GTT orders are active by currency pair and size. This setting applies to ESP trading in the Board, Full Book, and Ladder panels.


Quick Orders: Display - Choose whether you see just the increment amount or the incremented pips in the Quick Order drop-down list.

Quick Orders: Pip Increment - Set the pips increment in the Quick Order drop-down lists. The increment is either shown directly or is used to show incremented pips.

Quick Orders: Time in force - Choose when your Quick Orders expire.
