Previous Bar size (Need simple indicator)

[AnnaM]

Hi guys I just need a simple indicator to show the size (in ticks or in points) of the previous bar. I have an indicator to show the size of the CURRENT bar (Blue circle).
However, I would like to see the size of PREVIOUS BAR imprinted (orange circle) (and eventually disappear once a new "previous bar" formed, if that makes sense).

I cannot edit this indicator as I can't access the script and I don't know how to code Please help. Thank you very much.

Hi AnnaM, thanks for posting. Can you please Export and post the indicator you are using to draw the value on the current bar? See here for instructions on exporting:

Hello Anna,

For a quick programming challenge, I threw something together for you. Please see attached. I believe you can import this but you might need to compile it. I'm sure Chris can provide the proper instructions as I'm new to exporting/sharing NT code.

There are three Properties:
1. Number of Bars to show the bar size, including the current bar.
2. Offset (in ticks) to show the bar size above the high of the bar.
3. Font size (the font used is Arial).

Below is the class code for anyone interested.

Hope that helps!
Matt

Thank you so much!! This worked perfectly! Is there a way for me to change the font color though? As the light grey is barely visible on a white background
But thank you very much. Appreciate this!

Hi Anna,

Here's an updated version with a Points or Ticks selection and a font color option.

It's the same name so I hope it will just replace the previous one when you load it.

Kind regards,
Matt

You're welcome, Anna! You and anyone else, let me know if there are any issues.

[deshawn]

Hello I am interested in this indicator is there a way I can access it?

[NinjaTrader_ChrisL]

Hi deshawn, welcome in. I re-attached the sample that Stealth posted in case you can not download it from his post:


Kind regards,

[StealthM93]

Hi deshawn,

Glad your interested! Let me know if you have any issues or questions.

Thanks, NinjaTrader_ChrisL, for the re-post!

Kind regards,
Matt

[spiketrades9]

You're welcome, Anna! You and anyone else, let me know if there are any issues.

Can I bug you to make some updates to this?
My friend made this for Tradovate. It calculates the risk in $$ and changes colors based on high vs low risk. It also has a feature to add ticks. He adds 2 ticks, one for his stop entry and one for "one tick above" the signal bar.
Thoughts?

[StealthM93]

Hi spiketrades9,

Looks like you're asking for more of a strategy than indicator. For what you have in the screenshot, the indicator would need to know the trade sizing and $/point. Also, it appears that it is identifying the local tops/bottoms (or pivots). That's a rather involved request, more than a simple freebie to post here on the forum, in my opinion.

I wish you well,
Matt

For what its worth, I am unaware of the amount of work necessary. Thanks for letting me know. Can you help me understand why my NT freezes while adding the indicator to charts? It did not happen when I first downloaded but I can not load it anymore with out crashing.
Thanks

[StealthM93]

Hello spiketrades9,

Assuming you mean my indicator above, I have no idea why that would cause NT8 to freeze or crash. The indicator is simple, straightforward.
You'll need to NT Support to help. Perhaps NinjaTrader_ChrisL?

Matt
