ETF-CFD Ratio Bridge

11 ชั่วโมงที่ผ่านมา

This indicator helps traders visualize the relationship between ETFs and their corresponding CFD/Spot instruments. It allows you to trade on one chart while monitoring the equivalent price levels of the other instrument without mental math or switching screens.

Features

1. Ratio Table
A customizable table displayed on the chart (default: Top Right) that shows:
- Pair: The ETF and CFD pair being monitored.
- Ratio: The calculated price ratio (ETF / CFD).
- Prices: Real-time prices for both instruments.

2. Companion Price Label
A dynamic label that moves with the current price candle.
- Displays the equivalent price of the paired instrument.
- Example: If you are viewing SPY, the label shows the equivalent US500 price next to the candle.

3. Left Virtual Scale
A custom vertical axis drawn on the left side of the chart.
- Shows price levels for the companion instrument corresponding to the current visible chart range.
- Allows you to read "CFD prices" directly on an "ETF chart" (and vice versa) via the Y-axis.

4. Historical Levels lines
Visualizes recent market structure converted to the companion price.
- HH(x): Highest High of the last X bars (default: 20).
- LL(x): Lowest Low of the last X bars.
- Dashed lines extend to the right with labels showing the converted price at those key levels.

5. Closed Market Handling
Ensures the indicator remains useful even when the ETF market is closed (e.g., after hours) while the Futures/CFD market is open.
- Automatic Detection: The script detects if the ETF market is closed based on the timestamp.
- Fixed Ratio: Automatically switches to a user-defined "Fixed Ratio" when the ETF is closed.
- Continuous Updates: Prevents values from freezing, calculating a synthetic "Shadow Price" for the closed asset so you can continue to see projected levels based on the live CFD market.

Technical Explanation (The Math)

The indicator functions by calculating a dynamic ratio between the two instruments and using it to convert price levels.

Formulas
1. Calculate Ratio:
Ratio = Price(ETF) / Price(CFD)

2. Conversion:
- ETF Chart → CFD Price:
Equivalent CFD Price = Current ETF Price / Ratio
- CFD Chart → ETF Price:
Equivalent ETF Price = Current CFD Price × Ratio

Example (SPY vs US500)
- Scenario: You are trading on the SPY chart.
- Current Prices:
- SPY (ETF) = $500
- US500 (CFD) = $5000
- Step 1: Calculate Ratio
- 500 / 5000 = 0.10
- Step 2: Calculate Equivalent Price
- If SPY moves to $505, what is the US500 equivalent?
- 505 / 0.10 = 5050
- The indicator will display "US500: 5050" on the label and scale.

Supported Pairs

SPY (AMEX) = US500
GLD (AMEX) = XAUUSD
SLV (AMEX) = XAGUSD
IWM (AMEX) = US2000
QQQ (NASDAQ) = NAS100
IBIT (NASDAQ) = BTCUSD

Settings

- Symbols: Customize the ticker symbols for each pair if your broker uses different names.
- Fixed Ratio (Closed): Manually adjust the fallback ratio used when the ETF market is closed (default values provided).
- Visuals:
- Toggle Table, Labels, Scale, and Historical Lines on/off.
- Customize colors, text sizes, and positions.
- Right Offset (Bars from Current): Adjusts how far back (from the current live bar) the Left Virtual Scale is drawn. Increasing this moves the scale further to the left.
- Historical Levels:
- Lookback Length: Number of bars to check for High/Low calculations (Default: 20).

- Status: Shows Open or Closed. Highlighted in Orange (default) when using Fixed Ratio.

2. Companion Price Label
A dynamic label that moves with the current price candle.
- Displays the equivalent price of the paired instrument.
- Visual Change: Background turns Orange (default) when Market is Closed to indicate Fixed Ratio usage.
- Example: If you are viewing SPY, the label shows the equivalent US500 price next to the candle.

- Fixed Ratio: Automatically switches to a user-defined "Fixed Ratio" when the ETF is closed.
- Visual Cues: Table and Label change color to indicate "Closed" status so you know the Fixed Ratio is active.
- Continuous Updates: Prevents values from freezing, calculating a synthetic "Shadow Price" for the closed asset so you can continue to see projected levels based on the live CFD market.
