DAX futures can not be traded on sim account

[AdamS01]

I am placing buy market order for FDAX U5-EUX using
OrderId = Trade.buyMarket(
{
"symbol": getSymbol(), "qty": nQty,
"account": Trade.getCurrentAccount(),
"connectionID": Trade.getCurrentConnectionID()
});
When connecting to in build demo accounts EFS-AT stops executing with error:
Some order fields are wrong: Trigger Method

Hi AdamS01,

The 'Trigger Method' is a required field for the 'Stop'/'StopLimit' types of orders of the 'eSignal Paper Trading' broker. For this field EFS-AT uses a value which is specified in 'Order Defaults' for a symbol.
If you put an empty value in this field and lock the confirmation of EFS orders then when you place a 'Stop'/'StopLimit' order you will get the error that you referenced in your post: 'Some order fields are wrong: Trigger Method'.

With regards to the case described in your post - when you try to place MARKET order and get this error - it is an incorrect behavior.
This field should be ignored for the 'Market'/'Limit' types of orders.
We have created a ticket in our bug-tracker to fix this.
