Changing number of contracts traded

[pandyav]

Hello,
I am wondering if there is a way to change the number of contracts traded by a strategy in an automated way.

Eg. I'd like my strategy to buy one contract for every $10000 of balance that I have in my account. So, if the balance goes up to $20000, it will place trade for 2 contracts for $30000 it will place 3 contracts. But if the balance comes down to $20000 for some reason, it will automatically place trade for only 2 contracts.

Is there a way to accomplish this in NT?
Thanks.

Hi pandyav,

Yes, this is possible. You can have a variable for order quantity that is calculated any way you like. If you wanted access to the real time account values, there is method GetAccountValue()

double orderQuantity = GetAccountValue(AccountItem.CashValue) / 10000;
EnterLong(Math.Min((int)orderQuantity, 1)); //Math.Min used in case you get below 10000.

Hi,

I am new to NinjaTrader, and am just starting to evaluate the software and trying to set up some of my strategies to trade automatically.

I am having a similar problem to pandyav, but when I inserted the lines of code into my program, it still only trades one contract, while back testing; regardless of what I set the starting account value at.

Any help on this matter would be appreciated.

Thank You

Welcome to our forums - the GetAccountValue call would only work in real-time simulated / live trading, it would not work on historical data.

For backtesting, to use the entered AccountSize parameter please ensure your order qty for the strategy is driven ByAccount - http://www.ninjatrader.com/support/h...a_strategy.htm
