I have a question stepan7...

How are you determining IBGS? Only a couple ways I know...
1) track the FORMING of a bar in real-time, for example, has high of bar formed before the low, which many times, for that, and like characteristics, requires a bit of "guessing", and 2) wait until bar close, before analyzing semi-persistent bar-forming tracking data points.

My question stems from the knowledge that IBGS can happen at anytime, irrespective of the pricebar "case", and irrespective if the "case" at any moment during formation can be locked-in or not.

If only it was as simple as comparing close v open, compared against dom/non-dom segment

There are two answers mine and spydertrader's. Which of one you prefer? :)

1. Bar is Black/Red by HH/LL or FTP/FBP or Stitch Up/Down but it has O/C or C/C in the opposite direction - we got IBGS. It has nothing to do with the Volume. You have mentally split Volume: partial Up, partial Down.

2. Spyder take to the account that Abs(O/C) or Abs(C/C) > 1 tick, I don't. There are some reasons for that, it's long story to explain.

If it's not clear for you PM me I will sent the code.

3. And Yes, to determine IBGS you have wait to the End of the Bar.

P.S.
I think you are over complicate this stuff. In reality it's very simple :) but not easy. :D

There are two types of the IBGS:

1.Inter-Bar;
2.Intra-Bar.

1)if(Low[0] <= Low[1] && Close[0] > Open[0] + tick) for the long(vice versa for the short);
2)if(Close[0] <= Open[0] && Close[0] > Open[0] + tick) for the long(vice versa for the short).

Unless you come up with a link to authoritative source, it's you own invention.

Not at all my friend. If anyone should apologize, it is me for sounding sarcastic.
Completely unintended. Sometimes communication gets broken between brain and keyboard.
Your response was intelligent... even offered reasoning to the methods you use.

All is good on this side. Sorry for confusion. JHM 2.0 is now resuming...
 
Couldn't find many IBGS notes. But did find this snip from Spyder. Reminded me that I don't need or use IBGS. I do not trade at the "bug" level. Leaves, Limbs, and and an occasional Tree for me. My time frame, 2 minute, has plenty of "bugs" without me looking for them! :)

I'm sure IBGS code will be useful to others.


Spyder on the different levels of trading

In an effort to assist those following along, I have altered my annotation style to include only The Forest Level Resolution. Keeping in mind my previous post with respect to "How Big is the Forest?" Note the Gaussian changes which occur. Are they different on my chart when compared to your own? Do you 'see' things as they are, or as you'd want them to be? Are you monitoring on the correct resolution level, or do you only think you monitor correctly? In an effort to assist you to know the proper resolution level, I have added the following guidelines for data gathering.

Forest Level - Point Three Channels and Gaussians
Tree Level - FTT's (and the above)
Limb Level - Tapes (and the above)
Leaves Level - FTT's of Tapes (and above)
Bug Level - Intra-bar Changes (and above)

If you find yourself confused about a bar changing color halfway through a five minute period, are you really focused on the Forest? 'Cuz it sounds an awful lot like you are looking for bugs, on a leaf, on a limb, on a tree, in the Forest.

Stay focused on your current resolution level to allow you to properly learn about the next finer resolution level. From the Forest, you can learn about FTT's and flaws without concern for loss. From the Trees, you can learn about the tapes and how they contain temporary micro-trends throughout the day. Everyone must build a strong foundation at their current level of expertise, before moving forward.

I hope you find the above information helpful, and I'll post today's charts after adding some requested information.
 
Yes, It's good idea to read old posts.
Look on this trade - the only spyder's public trade that I know of.

I never looked on the actual ES chart - the data was not available.

Stepan7 (and anyone with a deeper understanding of the subject),

What are your thoughts on bar-to-bar degapping? I'm a little confused around the issue in that I remember Jack talked about interbar gaps as a result of an arbitrary time interval start/stop in-between a bbid/bask pair.

With my current understanding, it would be logical to just move the open on the current bar. That way the historical highs and lows are still accurate. But I feel this is not an accurate understanding of the concept, it's benefits, limitations and applicability.
