Coinbase Premium(/binance)

1 031
Script Overview
This indicator is designed to measure the price gap (premium) between Coinbase (BTC/USD) and Binance (BTC/USDT). Since Coinbase is often viewed as a proxy for institutional demand in the US, this "premium" helps traders identify whether buying pressure is coming from US-based institutions or global retail markets.

Key Components & Logic
1. Data Integration (Multi-Exchange)
The script uses the request.security() function, which is the standard in Pine Script v5 for fetching data from different symbols or exchanges:

Binance BTCUSDT: Represents the global retail market price.

Coinbase BTCUSD: Represents the US institutional market price.

Bitfinex USTUSD: Used as a "Stablecoin Peg" adjustment to ensure the comparison between USD and USDT is mathematically accurate.

2. Calculation Logic
Price Normalization: It multiplies the Binance BTC price by the USDT/USD exchange rate (binance_btc * usdt_peg). This ensures we are comparing "apples to apples" (USD vs. USD).

Premium Calculation: * USD Difference: Simply subtracts the adjusted Binance price from the Coinbase price.

Percentage (%) Premium: Calculates the percentage gap. Following your original code's logic, it uses the 2-bar delay ([2]) to smooth out minor data lag or specific historical points.

3. Visual Elements (UI)
The script is optimized for Dark Mode users with a "White" theme:

Histogram (Percent): Displays the percentage premium. A value above 0 indicates Coinbase is more expensive than Binance (Bullish signal for US demand).

Columns (USD): Shows the raw dollar difference with slight transparency (60%) to keep the chart clean.

Zero Line: A solid white line at the 0 level to clearly distinguish between a "Premium" (positive) and a "Discount" (negative).
