Circles - Support & Resistance Levels
Overview
This indicator plots horizontal support and resistance levels based on W.D. Gann's mathematical approach of dividing 360 degrees by 2 and by 3. These divisions create natural price magnetism points that have historically acted as significant support and resistance levels across all markets and timeframes.
How It Works

360÷2 Levels (Blue): 5.63, 11.25, 33.75, 56.25, 78.75, etc.
360÷3 Levels (Red): 7.5, 15, 30, 37.5, 52.5, 60, 75, etc.
Both Levels (Yellow): 22.5, 45, 67.5, 90, 112.5, 135, 157.5, 180 - These are "doubly strong" as they appear in both calculations

Key Features

Auto-Scaling: Automatically adjusts for any price range (from $0.001 altcoins to $100K+ Bitcoin)
Manual Scaling: Choose from 0.001x to 1000x multipliers or set custom values
Full Customization: Colors, line widths, styles (solid/dashed/dotted)
Historical View: Option to show all levels regardless of current price
Clean Display: Adjustable label positioning and line extensions

Use Cases

Identify potential reversal zones before price reaches them
Set profit targets and stop losses at key mathematical levels
Confirm breakouts when price decisively moves through major levels
Works on all timeframes and all markets (stocks, crypto, forex, commodities)

Gann Theory
W.D. Gann believed that markets move in mathematical harmony based on geometric angles and time cycles. These 360-degree divisions represent natural balance points where price often finds support or resistance, making them valuable for both short-term trading and long-term analysis.
Perfect for traders who use:

Support/Resistance trading
Fibonacci levels
Pivot points
Mathematical/geometric analysis
Multi-timeframe analysis
Notes de version
The code will now attempt to scale the range above and below what is detected. This way you can see more levels based on the current multiplier.
Notes de version
Levels with a digital root of 9 now show in a different colour
Notes de version
Rebuilt the code. Now it will show correctly on percentage based charts too!

Small bug fix
Notes de version
Fixed the auto scaling for a few charts.

Another bug fix for low caps in crypto

Another bug fix
Notes de version
Another attempt at clean level identification checks
Notes de version
Returning to an earlier version of the script which seemed to perform more consistently across charts until I have a better solution.
Notes de version
Script updated. Way more reliable across different charts. Works with percentage charts too.
There's also a repeat option to add levels on top of the range.
Notes de version
The nearest circle level now has a different style option so you can clearly see what the dominate level is.
Notes de version
Made the text size consistent
Notes de version
Updated the script so that if "Repeat levels" is turned on, it will always show the active level.
