Orders rejected in Live mode with IB.

Hi,

I'm getting "Cash needed for this order" error from IB with a real live account and a market order.

I've set SetBrokerageModel(BrokerageName.InteractiveBrokersBrokerage, AccountType.Cash);.

I'm using CalculateOrderQuantity(symbol, 0.93m) to get the proper quantity.

.93m is a totally random percentage that seems to work most of the time.

I'm buying TVIZ, a very volatile but low volume stock.

Since I don't have a margin, is there any ohter setting I have to use?

Do or can quant connect use current AskPrice only to evaluate market order quantity?

My goal is to always use 1m without any rejected orders.

Thanks

I called IB yesterday about a margin question.  The volitility products like you're mentioning have a variable initial margin require ment which can actually go over 100% meaning even if you had 50k in account you may not be able to buy 50k in the volitility product

Hi,

Thanks for the info. I'm trying to find numbers for the initial margin requirement but found nothing.

You won't.  You have to attempt a trade in the workstation and view the order confirmation or call them.  It's a total pain. They don't display margin information in any user friendly way
