Compra/Venda desta stock na TD Ameritrade apenas pode ser feita por telefone

Segue troca de mensagens que tive com a TD Ameritrade (apenas as partes que importam) para mais detalhes:
Me:
Hello. I tried to buy stock ROLL and I received a message saying:
"Order rejected: Opening transactions for this security must be placed with a broker. Contact us."
I appreciate if you can clarify and provide instructions on how I should proceed.
Thanks!

---------------------------
TD:
This specific stock needs to be placed with a broker. You can contact us at 1-800-669-3900 to proceed with the order, we do apologize for any inconvenience.

---------------------------
Me:

I have some questions and I appreciate if you can answer them:
1 - Is there a reason why this specific stock has this requirement for a broker?
2 - Is this any kind of limitation/requirement from the Company or from TD Ameritrade?
3 - Does it mean the only way to place a buy/sell order is though a phone call?
4 - In this case, is there any additional cost?
5 - Is there a way to know such limitation from any other stock, prior to trying to place the order through the internet interface? Or is there some kind of list of stocks which fall within this case?

------------------------
TD:
1. Some securities are subject to needing to be placed by a broker, there is not any one reason.
2. This is a limitation by the security.
3. This does mean that the only way to buy/sell the stock is through a phone call.
4. There is no additional cost for these trades.
5. The only way to know that this limitation is set for another stock is to submit an order and see if there is a rejection with this notification.

Rolo

Só se mudou recentemente por algum motivo, não tive problemas em fazer a compra em agosto do ano passado via home broker.

Eu comprei pela passfolio sem problema nenhum 

Também comprei via Homebroker da Ameritrade em setembro/20, alguma coisa deve ter mudado.

@Bastter Sim, até fui olhar de novo no meu histórico:


Cheguei a pensar que tinha feito algo errado, e tentei novamente.
Depois vou perguntar para eles se é algo que surgiu agora ou é temporário e até informar que outras pessoas conseguiram comprar no ano passado.
Mas realmente nunca tinha visto nenhum relato disso e achei bem estranho.
