Help plz...Three day low trailing stop

[JT1230]

I have tried dozen of times to create a strategy where long stop exit will be triggered when it touches the previous 3-day low. I would be grateful if someone could help.

Hello JT1230,

You can use Lows, which will hold an array of DataSeries objects holding historical bar low prices. A DataSeries object is added to this array when calling the Add() method in a Custom Strategy. Add a Daily Data Series to your chart so you reference daily bars.

What does it meant by [ the name "ExitLongStop" does not exist in the current context] ?

Hello JT1230,


Could you please reply with your script attached, so that I may investigate this behavior further?


You can attach your strategy to your response by going to File > Utilities > Export NinjaScript > Export selected source files > select your strategy > select the right arrow > Export. The file will be located under (My) Documents\NinjaTrader 7\bin\Custom\ExportNinjaScript.


You could post the script to your forum reply, or send an email to platformsupport [at] ninjatrader [dot] com with the script as an attachment. In the email please include a link to this forum thread.

I think the error appears because "ExitLongStop" is for NT7 and "ExitLongStopMarket" is for NT8, please correct me if I'm wrong. And I cant seem to be able to do a backtest using this strategy

[NinjaTrader_ShawnB]

Hello JT1230,
This is correct, if you are in NT8 you would need to use ExitLongStopMarket(). If you are still unable to backtest your strategy, use the steps outlined in my previous post to send us your script.

Is it possible for us to make three day high-low trailing stop instead of stick, percent and price?

Hello,
Hello,


To do this, set your SetTrailStop() value to the three day low.
