This one is a bit out there and more in the category of tool then indicator. But I've seen too much confluence around this concept and decided to make something to help visualize it and share with the community. Quarterly Theory is a time-based concept derived from some early ICT work. As far as I am aware, it was coined and outlined by Trader Daye. I am not the author of these concepts and will not be well suited to answer all questions you might have. I suggest you study Daye's twitter to gain more insight. This is purely a graphical aid for traders to be able to quickly determine Daye's Quarterly Cycles, and save Time while on the charts.

I have been inspired to create this tool for TOS by a very clever creator on Twitter (too) who has published a TradingView version here.

I have focused on the link above - the 6hr cycles and the 90m cycles.

These Quarters represent:

– Daily Cycle:

The Day can be broken down into 6H quarters. These Times roughly define the sessions of the Trading Day, reinforcing the Theory’s validity.

Dividing each of the above Daily Quarters into four, we obtain 90 minute quarters. The first one in a Trading Day – 90min Cycles of the Asian Session – follows as an example, in New York Time.

On to the tool and the options. The current version is intended to work on smaller, intraday timeframes.

Please note that the text on the image has been added manually to assist in understanding the intent of the tool.

There are a couple of quirks with how this interacts with TOS. The 'clouds' at the bottom will always have small gaps between them as TOS wants to leave a candle or so space between them. The smaller your selected timeframe, the smaller the gaps appear. Also, because the session day does not actually go until 6pm, I have elected not to put a 'Q4' for the end of the NY session. Would be happy to offer a version with that but it just looks visually off to me. Here is the shared link for the chart exactly as I have shown. I believe the only thing you need to do is minimize the size of your lower indicator:

The study color scheme is configurable - so you can select whichever 4 colors make the most sense for your charts for the 4 'phases' of the chart. And finally, on to the code:

I have been inspired to create this tool for TOS by a very clever creator on Twitter (too) who has published a TradingView version here.

I have focused on the link above - the 6hr cycles and the 90m cycles.

These Quarters represent:

- A - Accumulation (required for a cycle to occur)
- M - Manipulation
- D - Distribution
- X - Reversal/Continuation

– Daily Cycle:

The Day can be broken down into 6H quarters. These Times roughly define the sessions of the Trading Day, reinforcing the Theory’s validity.

- Q1 - 18:00 - 00:00, Asian Session
- Q2 - 00:00 - 06:00, London Session (True Open, Midnight New York Time)
- Q3 - 06:00 - 12:00, NY Session
- Q4 - 12:00 - 18:00, PM Session

Dividing each of the above Daily Quarters into four, we obtain 90 minute quarters. The first one in a Trading Day – 90min Cycles of the Asian Session – follows as an example, in New York Time.

- Q1 - 18:00 - 19:30
- Q2 - 19:30 - 21:00 (True Open)
- Q3 - 21:00 - 22:30
- Q4 - 22:30 - 00:00

On to the tool and the options. The current version is intended to work on smaller, intraday timeframes.

**I recommend using it on 15 minutes or below.**I have split the tool into two visual components - an upper study that plots the quarterly divisions, the true opens for each quarter (optional), midnight open (optional) and a label for each new day (optional). There is also an option to show vertical lines for the 6hr quarters vs the 90m quarters (default).Please note that the text on the image has been added manually to assist in understanding the intent of the tool.
