API companion not letting me open orders on the FTSE

[TheEdge]

Whilst working with my live account through the REST API on the API companion tool (and also with my own code in Excel), I encounter a problem when I try to create a new position with parameters below.

response   "errorCode":  "error.trading.otc.market-orders.not-supported-for-epic"

Any ideas on what I'm doing wrong or does it mean I can't POST (positions/otc) on the FTSE? 

{ 
    "epic": "OP.D.FTSE1.6750P.IP",
    "expiry": "MAR-23",
    "direction": "SELL",
    "size": "1",
    "orderType": "MARKET",
    "timeInForce": "FILL_OR_KILL",
    "level": null,
    "guaranteedStop": "false",
    "stopLevel": null,
    "stopDistance": null,
    "trailingStop": null,
    "trailingStopIncrement": null,
    "forceOpen": "false",
    "limitLevel": null,
    "limitDistance": null,
    "quoteId": null,
    "currencyCode": "GBP"
}
