Basic strategy by NT wizard

[Borsz]

Hi,
I am trying to learn ninja script programming by myself. As a first step I wanted to make a script which enters short if previous bar is green (close higher than open) and enters long if previous bar is red (close lower than open). It seemed very simple to make it in the wizard, but the script does not make what it should make.
Can you help me?

Hello Borsz,

Thank you for your post.

On the historical executions they will occur one bar after the condition is true. This will also occur when using CalculatOnBarClose = True on the real-time data. Please try setting this to CalculateOnBarClose = False and advise if the real-time trades (not historical or backtest) are correct.

Hi Patrick,

Thanks for you quick reply.
I modified to CalculateOnBarClose = False and ran it real time, but there is still problem existing: after reaching SL/TP inside a bar, it immeadiately enters again in the same bar. While, I want only 1 entry per candle: short entry at open of current candle if prev. candle was long; long entry at open of current candle if prev. candle was short.
How can I manage it in the wizard?

Hello Borsz,

Thank you for your response.

You can use the BarsSinceExit to wait one bar before the next entry: http://www.ninjatrader.com/support/h...ssinceexit.htm

Hi Patrick,

You mean just simply add BarsSinceExit == 1 conditon to the script in the wizard?
I tried it but now it does not tarde at all.
Thanks,

Borsz,

If you added this check to all the conditions then I would expect this to not work.

Essentially, the BarsSinceExit() requires that there was an initial entry and then exit.

Since there is no initial entry at the start the strategy, there is no exit to handle this condition.

You would want to have a separate condition to have the initial entry. Then have the regular conditions for exit, and then the BarsSinceExit() would be working at this point.

Yes, it sounds logical and right.
and how to add an initial eentry?
Thanks a lot,
Peter

Peter,

The images that I have attached below show how to create a sample Initial Entry and then use that to get a starting basis. The rest shows how to use the BarsSinceExit() with the condition.
