How can I find the supported order types for an instrument?

This information can be found in our reference data endpoints. Specifically you can specify a UIC and an AssetType and query GET /ref/v1/instruments/details/{Uic}/{AssetType}. In the response you will the field SupportedOrderTypes that will hold information on what order types are supported for that particular instruments:

{
  ...
  "AssetType": "FxSpot",
  ...
  "SupportedOrderTypes": [
  "Market",
  "Limit",
  "Stop",
  "TrailingStop",
  "StopLimit"
  ],
  ...
  "Symbol": "GBPAUD",
  "Uic": 22
}

In this example the supported order types are Market, Limit, Stop, TrailingStop and StopLimit.
