TradeStation Reports Brokerage Metrics for March 2022

PLANTATION, FL, April 7, 2022 - TradeStation Group, Inc. ("TradeStation"), the parent company of award-winning self-clearing online brokerages for trading stocks, ETFs, equity and index options, futures, futures options and cryptocurrencies, today reported certain monthly business metrics for March 2022:

• • 226,506 Total Customer Accounts, 55.3% higher than prior year

• • 21,985 Gross New Accounts, 120.1% higher than prior year

• • $12.0 billion Total Customer Assets, 16.4% higher than prior year

• • $2.9 billion of Total Customer Cash, 4.0% higher than prior year

• • 232,104 Daily Average Revenue Trades (DARTs), 14.4% lower than prior year

Comparisons to the prior year mean a comparison of the month or month-end, as applicable, of March 2022 to the month or month-end, as applicable, of March 2021.

Total Customer Accounts is the number of customer brokerage accounts with a positive account balance at the end of the period presented.

Gross New Accounts is the total number of approved customer brokerage accounts funded during the period presented, and includes accounts funded during the period presented that were opened and approved (but not funded) in a prior period, as well as accounts that were opened and funded in a prior period, but then went to a zero balance and were subtracted from Total Customer Accounts, but then were again funded during the period presented.

Total Customer Assets is total cash and assets held in customer brokerage accounts at the end of the period presented.

Total Customer Cash is the aggregate cash held in customer brokerage accounts (equities and futures accounts - no cash is held in customer cryptocurrency accounts) at the end of the period presented.

Daily Average Revenue Trades (DARTs) means daily average revenue trades made by customers. A revenue trade means one completed customer equities, options, futures, or crypto trade, regardless of the number of shares, contracts, or units included in such trade, and includes trades completed under TradeStation's "zero commission" plans (which are supported by payment-for-order-flow, or "PFOF," revenue). Each "side" of a futures trade is counted as one revenue trade. Partial fills of an equities order on the same day are aggregated and counted as one revenue trade. DARTs are calculated by dividing the total number of revenue trades in the period presented by the total number of "Trading Days" in the period presented. A "Trading Day" means each day during the period presented that trading is open on NYSE and Nasdaq markets. A day on which such markets close early, such as the Friday after Thanksgiving, is counted as half a day. DARTs is a general indicator, as each of the asset classes TradeStation offers has a different fee structure and level of profitability.

Included in both Total Customer Accounts and Gross New Accounts are customer cryptocurrency accounts opened and funded through a marketing promotion that began December 20, 2021 in which TradeStation makes the initial account funding for the customer (BTC equal to $10.00). Cryptocurrency accounts opened under this promotion represented 12,628 of the 13,919 total gross new cryptocurrency accounts added in the month of March 2022. This cryptocurrency account promotion is expected to end at the end of April 2022.

More information, including historical results for each of the above metrics, are attached.
