Updated Sigma-Level

1-Sigma-Level Indicator (for 28 FX Pairs)
This TradingView indicator calculates and visualizes the 1-sigma price projection range for the current FX pair, based on implied volatility (IV) and a user-defined reference price.
🔧 User Inputs
1. Implied Volatility (IV) Selection
You can choose which volatility term to apply:
ON (Overnight)
1W (1 Week)
1M (1 Month)
Each currency pair uses manually entered IV values (in %), grouped by base currency (USD, EUR, GBP, etc.).

2. Base Price Selection
You can define the price level used as the anchor for the sigma projection:
CurrentPrice — live market price
YesterdayClose — close of the previous day
LastHourClose — close of the last 1-hour candle
LastFriday — weekly close from last Friday
LastMonthClose — close of the previous monthly candle
LastYearClose — close of the previous yearly candle
These values are retrieved using the appropriate timeframe (D, W, M, 12M, or 60 for hourly).
📐 How the Calculation Works
The indicator calculates the 1σ range using this formula:
1σ Range = basePrice × (IV / √N) / 100
Where:
basePrice is the selected anchor price.
IV is the selected implied volatility for the current pair.
N is the number of periods per year, depending on the IV term:
√252 for ON (trading days)
√52 for 1W (weeks)
√12 for 1M (months)
The upper and lower bands are then:
1σ Up = basePrice + range
1σ Down = basePrice - range
These bands are plotted only during the current calendar week.
🖼️ Visual Output
