DOM Bid Ask AVC Indicator

[Ticked 10]

Hello All,

 

I found this nifty indicator and absolutely love it, but can't remember what site I got it on or from who. I trade live with OEC but use this indicator on Ninja demo. I understand that Easy Language code can be used in Open E-Cry but none of the bid ask indicators on this site replicate the Ninja code.

 

Goal is to "convert" this indicator to Easy Language for use in Open Ecry platform.

 

Any thoughts?

 

Thank you,

 

Vin

[Tams 20]

do you have a screen shot?

 

how does this indicator work?

[Soultrader 12]

Please post in the indicator forum is possible. Thanks!

[Ticked 10]

Soul,

 

Any way to delete these two posts? Tried to edit and delete but not sure what to do.

 

I'll repost the first post [only], along with a screen shot in the indicator forum.

 

This is a real time indicator that shows an up bar or down bar over a zero line revealing the shifting of bid to ask sizes for 5 levels of the DOM. Also has a numerical representation on the upper chart panel.
