1800 Standart Deviation

1800 Standard Deviation

This script automatically plots standard deviation levels calculated from the 18:00 open price (based on your selected timezone). It provides a clear visual framework to analyze market volatility and key price zones around the session open.

How it works

At 18:00 (configurable timezone), the script records the open price and calculates multiple standard deviation levels above and below it.

Each level is expressed in points (or pips) relative to the open.

Horizontal lines are drawn and extended automatically as new bars appear.

Labels display the corresponding deviation value.

Colored boxes highlight important ranges between levels, such as neutral or high-volatility zones.

Customization

Adjustable timezone (GMT, Paris, or others).

Option to enable or disable the 18:00 deviation drawing.

Automatic daily refresh at the specified time.

Use cases

Identify volatility zones and price deviation ranges around 18:00.

Determine potential reversal or entry zones based on standard deviations.

Use as a technical reference for intraday or swing trading setups.

Notes

The calculations are purely statistical and price-based — no indicators or moving averages are used.

This script is visual only and does not generate buy/sell signals.
