Charles Schwab is one of the top day trading brokerages in the U.S., primarily because of thinkorswim — a professional-grade platform that includes paper trading, Level 2 data, futures, complex options strategies, and a scripting language for custom alerts. The PDT rule requires a $25,000 minimum equity in your margin account if you make 4 or more day trades in any 5-business-day window. Schwab’s margin rates run 8.575% to 13.575% as of 2026.
thinkorswim: Schwab’s Day Trading Platform
thinkorswim (TOS) is free for all Schwab brokerage customers. It’s widely regarded as one of the best retail trading platforms in the industry — comparable to what professional traders use.

thinkScript lets you write custom indicators, alerts, and strategies using a scripting language built into TOS. Advanced day traders use thinkScript to build proprietary entry/exit signals and scanning criteria.
The Pattern Day Trader Rule at Schwab
Like all U.S. brokers, Schwab enforces FINRA’s PDT rule:
| Scenario | Result |
|---|---|
| Fewer than 4 day trades in 5 business days | No PDT restriction |
| 4+ day trades in 5 business days with $25,000+ equity | PDT status, unrestricted trading |
| 4+ day trades in 5 business days with under $25,000 equity | Account restricted to closing trades only |
| Account drops below $25,000 while PDT | Restricted until balance restored |
A day trade = buying and selling (or selling short and covering) the same security on the same day in a margin account.
Worked Example
David has $35,000 in a Schwab margin account. He day trades individual stocks twice on Monday, once on Tuesday, and once on Thursday. That’s 4 day trades — David is flagged as a PDT. His equity is above $25,000, so he can continue trading. Two weeks later, a bad trade drops his equity to $23,000. Schwab restricts his account. He deposits $2,500 to restore the balance above $25,000 and trading resumes normally.
Margin and Day Trading Buying Power
Pattern Day Traders at Schwab get 4:1 intraday buying power:
| Account Equity | Day Trading Buying Power (4:1) | Overnight Margin (2:1) |
|---|---|---|
| $25,000 | $100,000 intraday | $50,000 overnight |
| $50,000 | $200,000 intraday | $100,000 overnight |
| $100,000 | $400,000 intraday | $200,000 overnight |
Positions closed before the end of the trading day use the 4:1 intraday margin. Any position held past 4 p.m. ET converts to overnight margin (2:1 Reg T).
Schwab Margin Rates (2026)
| Debit Balance | Annual Rate |
|---|---|
| Under $25,000 | ~13.575% |
| $25,000–$49,999 | ~12.575% |
| $50,000–$99,999 | ~11.575% |
| $100,000–$249,999 | ~10.325% |
| $250,000–$499,999 | ~9.575% |
| $500,000–$999,999 | ~9.075% |
| Over $1,000,000 | ~8.575% |
Day traders who close all positions by end of day avoid overnight margin interest entirely. If you routinely hold overnight positions, compare Schwab’s rates to Interactive Brokers, which offers significantly lower margin rates for high-balance accounts.
What Day Traders Can Trade at Schwab
Unlike some brokers, Schwab via thinkorswim supports nearly every asset class for active traders:
- Equities — stocks, ETFs, ADRs
- Options — all strategy levels including naked calls/puts (with appropriate approval)
- Futures — /ES (S&P 500 e-mini), /NQ (Nasdaq), /CL (crude oil), /GC (gold), and more
- Futures options — options on futures contracts
- Forex — currency pairs (limited)
Futures trading at Schwab via TOS is a notable advantage. Futures markets trade nearly 24 hours and are not subject to the PDT rule — some traders use futures specifically to avoid PDT constraints while maintaining active trading.
Schwab vs Fidelity vs E*TRADE for Day Trading

For serious day traders, thinkorswim’s edge is significant — the paper trading simulator, scripting tools, and futures access all make Schwab the top pick among major retail brokers.

Risks of Day Trading
The vast majority of retail day traders lose money. FINRA studies and academic research consistently show that fewer than 20% of day traders are profitable over a multi-year period. Leverage amplifies losses — a 4:1 margin position is wiped out by a 25% adverse move. Schwab’s educational content and paperMoney simulator are useful tools, but no broker can substitute for disciplined risk management.
