This indicator display the current lowest and the highest value of btc on a set of exchanges for a define type of market. Bitcoin Spread was originally made by @DayTradingItalia, i have bring his indicator to pine v4, add add some stuff to it:
5 Type of BTC Market : USDT Swap, USD and Futures (current/next contract)
@mrgr888n, He should work on every ticker, maybe I should have described the operation of the indicator a little more but I had considered that these use cases were narrow and that the people interested will read the code and if needed will mod it, but any way i give i short description:
This indicator measure in "real time" the price difference between a small list of hard-coded ticker , not the difference between the Bid & Ask on the current ticker, the key-point to keep in mind is that crypto market are highly inefficient, market data don't mean the same thing on every exchange.
