How to stop a strategy by programming?

[Follow Shadan]

I wonder if there is a way to implement this:

The strategy has been running for a while, and when some conditions are met, I want to stop the strategy automatically.

Of course, one simple way is to "do nothing" in OnBarUpdate after the conditions are met, but is there any way to fully stop it (by programming)?

Hi Follow Shadan, you mean like hitting the 'Start / Stop' button manually? This is unfortunately not possible with NinjaScript, but you can simply set a flag and then stop issueing any orders when your conditions are met.

I personally have programmed states into my strategy so like if buy conditions are all valid set a variable like buypostion = true then when the trade has finished (eg flat) set buypostion back to false. This stops within the code double buys.

Also i use the same methods to create a lockdown state for my strategy so that when conditions are valid the strategy goes into basically do nothing OnBarUpdate() mode until i restart it manually.

eg.

if (buyconditions == true && lockdown == false)
{
//trade actions
}

if (X == X)
{
lockdown = (true);
}

Maybe it is not the best way to achieve this but it has worked and does work for me.
