Changing parameters in running strategies

[Loki45]

2 related questions, actually.

1. Is it possible to change an input parameter while a strategy is running?

2. If not, I would have to stop the strategy and enter a new value. However, the information stored in variables during the previous session is lost then. Is it possible to store variables (for example, time elapsed or profit information) somewhere outside the strategy and retrieve them after the next session starts?

1. Unfortunately not while the strategy is already running.

2. You could try a text file, but this is not supported. Perhaps this reference will give you some ideas though: http://www.ninjatrader-support2.com/...ead.php?t=3476

It's possible, but it is outside of the realm of Ninja Trader and into the realm of C#. I've got a couple of things running that do just what you are asking.

I am a newbie for programming but I think we can write the variables to a text file and retrieve back when needed in c#. Just a suggestion .Try if it works

Are you doing it with text files like the other two posts are suggesting?

my solution

Hello,

some time ago I developped a solution for changing paramters in a running strategy.
As I see request here I decided to make my solution available to other NinjaTrader users.
Please undrstand that this cannot be for free as I put significant effort and time into this.

Please have a look at
