Arbitrage BR STOCK / USA STOCK

This Indicator was made to show the BRL difference between an Stock in Brazil's B3 and it's respective ADR traded in the USA.

By default, it will show the spread between PETR4 and it's ADR PBR.A using the USD-BRL pair from Forex.

You can personalize this indicator to any Stock of your preference, and also change to any USD-BRL pair negotiated that you want. You'll have the following options to do so:

B3's Stock Ticker -> Ticker negotiated at B3.
USA's Stock Ticker -> The respective ADR of the first option.
ADR's Multiplicative Factor -> How many B3's Stocks are equivallent to the USA Stock (found at the name of the ADR on Trade View).
BRL/USD Market of Preference -> Which market you want to use to transform the price of the ADR from USD to BRL.
Dollar Divisor -> The BRL must be equivallent to 1 Dollar for the script to work. So, if you want to use a USD/BRL market that does not represent this relation, you must divide it by some number to do so. For example, if you want to use B3's DOLFUT, than you must set this parameter to 1000 (because the points show at B3's DOLFUT are the amount of BRL equivallent to 1000 Dollars). Also, if you are using a market that trades Dollar equivalent to 1 BRL (Globex's 6LFUT, for example), then set this parameter to 0.
Timeframe -> Recommended to be the same of the chart to better visualisation.
