Price Multiplier/Transformation for Synthetic Instruments (ETF-to-Underlying Mapping)

[amccall144ytf]

I'd like to request a price multiplier field in Multibook Customizer (or as a new Tradermap Pro filter) that allows mathematical transformation of an instrument's price axis before combining it with other instruments.
 Use Case: I want to overlay IBIT (iShares Bitcoin ETF) orderbook/heatmap data onto a BTC perpetual futures chart. IBIT trades at ~$57 while BTC trades at ~$100,000. Each IBIT share represents approximately 0.00057 BTC, so the multiplier would be ~1757x.
 Being able to see where institutional liquidity is stacking on IBIT mapped to the equivalent BTC price levels would be extremely valuable for identifying key support/resistance that isn't visible on crypto-native venues alone.
 Current Limitation: Multibook Customizer only allows combining instruments that share the same price scale. Tick size controls display granularity but doesn't transform the underlying price values.
 Proposed Solution: Add a "Price Multiplier" field per instrument in Multibook Customizer settings. For example:

• Instrument: IBIT
  
• Price Multiplier: 1757
  
• Result: IBIT orderbook data displayed at transformed price levels (IBIT $57 → $100,149 on chart)
  

This would also be useful for other ETF/underlying pairs (GLD/Gold futures, SPY/ES, etc.) and potentially for spread analysis.
 Thanks for considering.

Yes that would be useful, Trading View has a basic mathematical operator function. Perhaps it could be simplified to last traded price only if the computational overhead is too high.
