Trade based off of Sim account size

[shazzmoe]

I want to test how a system I have written will perform when I position size based on current account size. Is this possible?

Exaple: Start with $25000. Each trade will risk 5% of the total current account (so it trades heavier as it increases and lighter as it decreases)

My system already has a variable which takes in dollar amount to risk so I can manually trade this but ideally I would like it to look at the account size and find a percentage so I can backtest my method.

shazzmoe, it is possible with NinjaTrader 7 to access your account size while running a strategy live (not necessarily with real money) by using the GetAccountValue() method.

Another option would be to create a variable that you input the starting account balance into, and then when each trade closes, you can update that value to run your position sizing calculations.

This sample goes over how to use performance data in your strategy.
