Are contingent orders actually supported?

[mw66]

Hi,

I'm reading this doc:

https://apisb.etrade.com/docs/api/order/api-order-v1.html#/definitions/OrderDetail

conditionType	string	The type of comparison to be used in a conditional order (contingent orders are not supported in API currently)	CONTINGENT_GTE, CONTINGENT_LTE
conditionFollowPrice	string	In a conditional order, the type of price being followed	ASK, BID, LAST

And found it's confusing: on one hand, the doc listed all the fields needed by the contingent orders, on the other hand, it also says: it's not supported.

So I am wondering if it's actually supported?

Has anyone tried to place contingent orders using API before? What's your experience?

Thanks!

There is a placeholder for contingent orders in the API but doesn't seem to work. Tried the following with no luck.
