@dawsh2 FINRA has not officially published the new rules and guidelines regarding PDT and daytrading. It is, however, expected that they will be within several weeks. The soonest brokers can implement them is 45 days after their publication. Alpaca has anticipated this rule change, so that is the expected timeframe for implementation.

That’s excellent news. So to be clear, we’re looking at closer to 45 days post publishing of the guidelines versus 18 months?

@dawsh2 Yes, 45 days would be a good expectation. Certainly not 18 months.

FYI, I just poked around and found this from April 20th and it states 45 days from then (earliest) would be June 4th, and the latest (18 months) would be October 20th, 2027. It also states “FINRA is planning to issue shortly a separate Notice announcing the availability of interpretive guidance and other resources”. :slight_smile:

@Dan_Whitnable_Alpaca , I’ve seen this June 4th date circulating a bit - is there truth to it?

@dawsh2 FINRA has filed amendments to Rule 4210 that replace the current Pattern Day Trader (PDT) provisions with a new intraday margin framework. The SEC has approved the proposed rule change, and FINRA has announced the effective date of June 4, 2026 via Regulatory Notice. Alpaca will implement these changes on that date.

Here is what this means for your account.

What Is Going Away

  • The Pattern Day Trader Designation. Your account will no longer be classified as a PDT regardless of how many day trades you make.

  • The $25,000 minimum equity requirement for day trading.

  • Day trade counting and PDT protection. The system will no longer track or limit the number of day trades on your account.

  • Day trading buying power. 4x buying power will be derived in real-time, no longer relying on previous day balances

  • PDT-based restrictions. If your account is currently restricted due to a PDT violation, that restriction will be lifted when the new framework goes live.

  • FDIC Sweep Program limitations tied to PDT designations. Trading API users previously ineligible for the FDIC Sweep Program due to PDT status will be able to enroll in Alpaca’s High-Yield Cash program.

What Is Replacing It

FINRA is replacing the PDT provisions with an intraday margin framework. Under the new rules:

  • Intraday Buying Power replaces Day Trade Buying Power. This is a running calculation of your available margin for intraday positions, updated throughout the trading day based on your equity, positions, and intraday profit and loss.

  • Intraday Margin Calls replace Day Trade Margin Calls. If your positions exceed your available intraday margin, you will receive a margin call. If you repeatedly fail to meet intraday margin calls within five business days, your account may be restricted for up to 90 calendar days.

  • Pre-Trade Checks will reject orders that would put your account into a margin deficit, helping prevent overextension in real time.

  • Increased Buying Power Availability: For leverage-enabled accounts, the minimum equity requirement for 4x intraday buying power has been lowered from $25,000 to $2,000.

The new system still has meaningful guardrails. The difference is that those guardrails are based on your actual margin exposure during the day, not on a count of how many times you traded.

What You Need to Do

If you use the API directly: Audit your integration for references to pattern_day_trader, daytrade_count, or daytrading_buying_power fields as they will be deprecated from the API on June 4, 2026. Plan to replace these with buying_power, as the previous fields will be completely removed by July 6, 2026.

These fields will return the following values until their complete removal from the API:

  • pattern_day_trader = false

  • daytrade_count = 0

  • daytrading_buying_power = buying_power

If you trade through the Alpaca Dashboard: No action is required. The changes will take effect automatically on your account on the effective date.

Timeline

FINRA’s Regulatory Notice sets the effective date at June 4, 2026. Alpaca will implement the changes on that date.
