How to get tradable amount from online broker with margin?

[warcious]

Hello,

My question is regarding risk-management, and I need to know which amount I should read from my online broker when calculating my trade position for each particular trade.
In most cases, the available trade amount is calculated like this: Equity (Cash + papers) - (Margin requirement) = Current Available Funds.

As I will use FXCM and Ninjatrader Continuum, I need to know how to fetch this amount from my online broker in order to calculate the correct tradable amount using a Ninjatrader strategy for a particular currency pair or stock instrument.

Any advice or information is appreciated!

Thanks!

Hello warcious,

Thanks for your post.

You can use GetAccountValue() for each account: http://ninjatrader.com/support/helpG...countvalue.htm

Thank you for your answer Paul. But which of these three items corresponds to my formula:
Equity (Cash + papers) - (Margin requirement) = Current Available Funds.
----
Ninjascript:
GetAccountValue()
Possible values:
AccountItem.BuyingPower
AccountItem.CashValue
AccountItem.RealizedProfitLoss

Hello warcious,

Thanks for your reply.

Regrettably not all items are available to fulfill your formula, please see: http://ninjatrader.com/support/forum...ead.php?t=5474 for what is available by broker/connection.

So what you are saying that for:
1)
FXCM I can only fetch the
Cash Value

and for
2) Ninjatrader Continuum I can only fetch
Cash Value
Realized PnL

Then how could I fetch my available trading amount including my margin?
Maybe I can manually enter the margin requirement somehow?

Hello warcious,

Thanks for your reply.

Yes, you could create input variables to hold the manually entered information.

In terms of margin, you can edit the instruments (va the instrument manager) and add that value (as there is a field for it) and then retrieve in Ninjascript through the undocumented code of Instrument.MasterInstrument.Margin.
