How to check whether account margin is enough to open position

[rfsettling]

Hello,

If i try to open position with too large size I have Ninja's message box "cannot accept order... not enough excess margin"

I want to check before sending order whether I have enough margin to open position
I suppose I need to use Account.GetAccountItem method, but I don't know which exactly parameter I have to use and what formula must be to get the answer "enough/not enough"

I opened the related documentation

https://ninjatrader.com/support/helpGuides/nt8/en-us/?accountitem.htm

but have not found any description for values

Hello rfsettling,

Thank you for your note.

I have attached a sample strategy which checks initial margin before entering long.

Please let us know if you need further assistance.

Thanks
One quick question: in your example Quantity of entry is not involved in calculation. If I use Quantity>1, should I multiply margin to my quantity?

Hello rfsettingling,

Good point. I would test the following,

	if(xAccountSize > StratInstrumentInitialMargin * TradeSize)
				EnterLong(TradeSize);

Please let us know if you need further assistance.

I already experimented with it, but it seems the logic is different to simple mutliplication. Let's consider ES futures. Initial margin $4950. If it is for one contract, then opening 20 contracts is maximum I can send for 100 K deposit. But I sent 50 contracts and more and Ninja accepted those orders

I tried to read user's manual for Risk window, to understand what each parameter means, but it also contains very scarce information.

Hello rfsettling,

If you open a super dom and queue up fifty and submit the order, does NinjaTrader accept the order?

I look forward to your reply.
