It depends on which price a broker is choosing to display as their default one. Each instrument has three prices:
- Bid (SELL)
- Ask (BUY)
- Trade (Last Trade Price)
If brokers choose to utilise market data of the same type, such as Ask, they should be equal if they receive quotes from the primary exchanges of the instrument. However, some brokers may opt not to work with the primary exchange due to price constraints and instead choose smaller alternative exchanges that may offer less favourable prices, resulting in slightly different Bid, Ask and Trade quotes.
❗️ Important
The Trading 212 Invest and Stocks ISA charts display only the Last Trade Price, which provides information about the instrument's most recent transaction and serves an indicative purpose.
