No combination of null or "-", will allow me to open a position. I either get invalid Level set no matter if I try null, 0, "-", if I set a price which I shouldn't have to with a Market Order I then get, "errorCode": "validation.null-conditional-set-value.request", I have cycled through setting and un setting all the parameters, but cannot get it to accept the order. Please can someone give me an indication of what the issue is and potentially try it on the companion themselves as I am lost for ideas? I feel like it was working just a week ago but now no longer? Last tried combination: { "epic": "IX.D.FTSE.DAILY.IP", "expiry": "-", "direction": "SELL", "size": "1", "orderType": "MARKET", "timeInForce": "FILL_OR_KILL", "level": "5962.0", "guaranteedStop": "false", "stopLevel": null, "stopDistance": null, "trailingStop": null, "trailingStopIncrement": null, "forceOpen": "true", "limitLevel": null, "limitDistance": null, "quoteId": "test", "currencyCode": "GBP" } Thank you.
