Error on subscribe to OnAccountUpdate()

[Austiner87]

Hi NT8 Support,

I am seeking to print the AccountItems in my strategy. Here is my code:




protected override void OnAccountItemUpdate(Account Sim101, AccountItem.TotalCashBalance accountItem, double value)

{
Print(string.Format("{0} {1} {2}", Sim101.Name, AccountItem.TotalCashBalance, value));
}





But I get this error: "TotalCashBalance does not exist in the type NinjaTrader.Cbi.AccountItem

Please let me know what I am doing wrong. Also, I'd like to subscribe to get all account items, not just the total cash balance. How can I do this?

Hello Austiner87,

Thanks for your post.

Please see the Help Guide for syntax on using this method.

OnAccountItemUpdate - https://ninjatrader.com/support/help...itemupdate.htm

Available AccountItems - https://ninjatrader.com/support/help...ccountitem.htm

To see which AccountItems will be available with your connection, please see the grid at the bottom of the Accounts tab documentation.

Accounts tab - https://ninjatrader.com/support/help...TheAccountsTab

Checking the documentation we can see the following as the correct syntax.

protected override void OnAccountItemUpdate(Account account, AccountItem accountItem, double value)

If you want to print out TotalCashBalance, that would look like:

protected override void OnAccountItemUpdate(Account account, AccountItem accountItem, double value)
{
    if (accountItem == AccountItem.TotalCashBalance)
        Print(String.Format("Acct: {0} TotalCashValue: {1}", account.Name, value));
}

If you want to check for different account items, you can set up conditions to check for those account items like I have demonstrated for AccountItem.TotalCashBalance above.

We look forward to assisting.

Hi NT8 support!

I still cannot get this to print in the output window for TotalCashBalance. I pasted in the code above exactly into my code but no output appears for TotalCashBalance.

Do I need to declare variables for TotalCashBalance?
Does any of the text above such as Account account or account.Name need to be replaced with the actual account name (Playback101 for testing purposes)?

I am looking to use the account items for calculations within the strategy with other variables, so if I have a variable named "VariableX" how can I build a formula in the OnBarUpdate() that has syntax:

VariableX = TotalCashBalance - SystemPerformance.AllTrades.TradesPerformance.Curr ency.CumProfit

Thank you!

Hello Austiner87,

We will need to get an AccountItemUpdate for TotalCashBalance to see an update with the snippet I gave in post #2.

Do you see this field change in the Accounts tab of the Control Center when you have a Total Cash Balance column added when you expect to see your print? If this value is unused with your account, are you looking for something else, like AccountItem.CashValue?

If you are looking to get a snapshot of an AccountItem, I suggest using Account.Get instead. OnAccountItemUpdate would be used to check when these AccountItems change.

I.E.

Print(Account.Get(AccountItem.CashValue, Currency.UsDollar));

Print(Account.Get(AccountItem.TotalCashBalance, Currency.UsDollar));

You could use Account.Get in OnBarUpdate to get a snapshot and use that in your code, or you can save your TotalCashBalance/CashValue AccountItems from OnAccountItemUpdate to a class level variable to use it in OnBarUpdate.

You can learn more about variable scope from educational C# resources that can be found external to NinjaTrader. A publicly available resource is linked below.

Scope - https://www.geeksforgeeks.org/scope-...es-in-c-sharp/

Please also note that AccountItems are only going to be relevant when the strategy is trading live with realtime data. If you include reference account items when the strategy processes historical data, it would not be relevant. Additionally, the AllTrades collection includes both historical and realtime trades, and the historical trades would not be relevant to the current account standing since they are virtual trades. RealtimeTrades may be recommended instead when comparing against account values.

RealtimeTrades collection - https://ninjatrader.com/support/help...timetrades.htm

You could consider separating logic that should be processed with Realtime data only by making State checks in your code.

For example:

if (State == State.Historical)
    return;

The above will skip processing historical data for all code underneath the return; line of code.

States - https://ninjatrader.com/support/help...nt8/?state.htm

We look forward to assisting.

Hello Jim,

when using

Print(Account.Get(AccountItem.CashValue, Currency.UsDollar));
Print(Account.Get(AccountItem.TotalCashBalance, Currency.UsDollar));

with a Sim101 account and a simulated data feed, I receive 0 for the two AccountItems.

Why?

Kind regards
Gerik

Hello Gerik,

Thanks for your message.

When I test this in a strategy that is applied to a Sim101 account, I get the same prints that are seen in the Accounts tab of the Control Center. (See attached screenshot.)

Please test the same prints in a separate strategy and apply the strategy against the Sim101 account and compare with the Accounts tab to test.
