Adjusting trade size based on funds availability

[StealthM93]

Hello,

How do I obtain available funds/margin for entering a trade? I would like to the trade quantity based on available, usable funds.

In looking at the Help documentation, is this correct?

double buyingPower = Account.GetAccountItem(AccountItem.BuyingPower, Currency.UsDollar).Value;

That seems like a lot of "extra" code to access an attribute on an account. Why doesn't the Account object have straightforward properties?

Thanks,
Matt

Hello, thanks for writing in. Using the Account object is the correct way to access account values in the strategy. The method to access any account item is Account.Get()

Hello Support / Chris,

When I using this code to obtain the buying power in Playback, I'm getting 0.0. In the Control Panel, it clearly shows $100,000 for the Playback account.

double buyingPower = Account.Get(AccountItem.BuyingPower, Currency.UsDollar);

Is this the correct code to get the buying power for a given trade? That is, with this buyingPower variable, I want to determine the number of contracts I should trade (code not shown).
If it is the correct code for live trading (I've not tested/confirmed yet), what the correct code for playback?

Thanks,
Matt

Hello Matt,

Neither the Sim101 nor the Playback accounts provide a Buying power account item.

Check the Accounts tab of the Control Center and you see the Buying power is 0 for the Playback account.

However, the CashValue is available, and you can use this.
