The brokerage posted 4.31 million daily average revenue trades (DARTs) in June, a spokeswoman told Business Insider, as traders capitalized on pandemic-fueled volatility. TD Ameritrade's June DARTs reached 3.84 million, Interactive Brokers posted 1.86 million DARTs, Charles Schwab's June sum hit 1.8 million, and E-Trade's DARTs totaled 1.1 million. Robinhood's second-quarter DARTs were more than double the sum seen in the first quarter, the spokeswoman added. Visit the Business Insider homepage for more stories .
