TL;DR

Interactive Brokers remains the default for serious active traders, on execution quality, global market access and the lowest margin rates in the industry. TradeStation is the best all-round platform for someone trading a few hundred thousand shares a month: $0 commissions with clearing at $0.003 per share on the entry tier, dropping to $0 above 10 million shares, with its desktop platform included for brokerage clients. Lightspeed is built for genuine high-volume scalping, from $0.0035 down to $0.0010 per share by monthly volume. Webull is the strongest free option with no deposit minimum. Robinhood is the easiest to start on and the weakest tool to actually day trade with. Before any of that: FINRA has replaced the pattern day trader equity minimum with intraday margin requirements from June 4, 2026, but brokers can phase the change in until October 20, 2027, so ask yours which rule applies to your account.

5 tools compared: Interactive Brokers, TradeStation, Lightspeed, Webull, Robinhood
TradeStation (best for: Active traders who want a professional platform with a published, tiered rate card): From $0/trade on US stocks and ETFs plus $0.003/share clearing under 100K shares/month; desktop included.
Lightspeed (best for: High-volume scalpers and anyone whose edge depends on fill quality): From $0.0035/share (under 250K shares/month) or $3.99/trade (under 250 trades/month).
Webull (best for: Traders who want real charting and Level 2 without a platform subscription): Zero commission on US-listed stocks and ETFs; no deposit minimum.

Day trading platforms are compared on commissions and chosen on execution, which is why so many comparisons are useless. Nearly everyone now advertises zero commission, and for someone placing four trades a month that genuinely is the whole story.

At forty trades a day it is barely the beginning: what you pay is a stack of per-share clearing, routing fees, platform subscriptions, market data and, if you short, borrow costs.

The other thing most comparisons skip is the rule change underneath the whole decision.

For two decades, four or more day trades in five business days in a US margin account made you a pattern day trader who had to hold $25,000 in equity.

FINRA replaced that with intraday margin requirements effective June 4, 2026: no $25,000 minimum and no trade counting, but your account must carry enough equity during the day for the positions you hold. Brokers may keep the old rule until October 20, 2027, so check which one your firm applies before you fund an account.

Top Pick

Interactive Brokers

The professional default, chosen for execution quality, global market access and margin rates nobody else matches.

Pricing: IBKR Lite: commission-free US stock and ETF trading. IBKR Pro: tiered per-share pricing.

Best for: Serious active traders, anyone trading outside the US, and anyone carrying margin

Pros

Consistently the lowest margin rates in the industry, which matters as much as commissions if you carry positions
Access to more than 100 markets globally from one account, rather than US equities only
Deep short inventory and real locate capability, which most retail platforms simply do not offer

Cons

Trader Workstation has a genuinely steep learning curve and looks like it was designed by engineers, because it was
The unbundled fee structure (data, platform, routing) takes real effort to model before you know your true cost

TradeStation

The best-documented rate card in active trading, on a desktop platform built for strategy testing as well as execution.

Pricing: From $0/trade on US stocks and ETFs plus $0.003/share clearing under 100K shares/month; desktop included.

Best for: Active traders who want a professional platform with a published, tiered rate card

Pros

Every tier is published, so you can calculate your exact cost before opening an account
Clearing drops to $0 per share above 10 million shares a month, which is genuinely competitive at volume
Strong historical data and strategy backtesting built into the same platform you trade on

Cons

Clearing of $0.001 to $0.003 per share applies below 10 million shares a month, so $0 commission is not a $0 trade
Options at $0.80 per contract on the entry tier is expensive next to the retail apps

Lightspeed

Direct-access trading built for people who measure their costs in tenths of a cent per share.

Pricing: From $0.0035/share (under 250K shares/month) or $3.99/trade (under 250 trades/month).

Best for: High-volume scalpers and anyone whose edge depends on fill quality

Pros

Publishes both a per-share and a per-trade schedule, so you can pick whichever matches your order profile
Genuine direct market access with granular routing control, which is the reason experienced traders use it
$0.0010 per share above 6 million shares a month, with custom pricing above 15 million

Cons

The $0.25 per-trade minimum makes small orders disproportionately expensive at low volume
Aimed squarely at experienced traders; there is little hand-holding and no reason to start here

Webull

The strongest free platform, with charting and depth-of-book that punch well above a zero-commission app.

Pricing: Zero commission on US-listed stocks and ETFs; no deposit minimum.

Best for: Traders who want real charting and Level 2 without a platform subscription

Pros

No commissions and no deposit minimum, so the cost of finding out whether you can do this is very low
Charting, indicators and Level 2 data are far better than the typical commission-free app
Paper trading is solid, which is where anyone new should spend their first three months

Cons

No true direct market access or routing choice, so fill quality is out of your hands
Short inventory and locate capability are limited compared with a professional broker

Robinhood

The simplest way in and the least capable tool once you are actually trading intraday.

Pricing: Commission-free stocks, ETFs and options, plus a $0.04 fee per options contract.

Best for: Beginners placing occasional trades, not sustained day trading

Pros

The lowest options contract fee here at $0.04, which is genuinely cheap for occasional options trades
The cleanest onboarding of any broker on this list
Fractional shares make position sizing easy on a small account

Cons

No Level 2 depth or routing control worth the name, which is disqualifying for real intraday work
The interface is designed to make trading feel easy, which is the opposite of what a new trader needs

What it is

A day trading platform is a broker plus an order-entry application, and the two halves matter separately. The broker determines your commission schedule, which markets you can reach, your margin rate and whether you can locate shares to short.

The platform determines how fast you can act: hotkeys, Level 2 depth, direct market access to a specific exchange rather than a smart router, and how the software behaves when volatility spikes. Retail-first apps bundle a simple platform with a simple fee schedule.

Professional brokers unbundle everything, which looks more expensive on the homepage and is usually cheaper at volume.

Why it matters

At active-trading volume, pricing model beats headline rate. Per-share pricing rewards large orders in cheap stocks and punishes anyone trading thousands of small tickets; per-trade pricing does the exact opposite.

Lightspeed publishes both schedules precisely because the answer flips depending on how you trade: at 300 trades a month of 100 shares each, a $3.50 per-trade rate costs $1,050 while per-share at $0.0035 costs about $105. Reverse the size and the ranking reverses with it.

Add market data, routing fees and, where one applies, a platform subscription, and the cheapest broker on a homepage is regularly the most expensive one on your statement. Model your own order profile, not a generic one.

Key features to look for

Per-share versus per-trade pricingEssential

The single biggest cost variable. Per-share suits large orders and few tickets; per-trade suits many small tickets. Run your own average order size through both schedules before choosing.

Direct market access and routingEssential

Whether you can send an order to a chosen venue instead of a smart router, and what that routing costs. This is the difference between retail apps and professional platforms, and it shows up in fill quality on fast moves.

Platform and market data fees

Desktop software and real-time Level 2 data can be separate line items. TradeStation includes its desktop for brokerage clients but charges $99.99/month to use it without an account, and data fees can exceed your commissions at moderate volume.

Short locates and borrow availability

If you short, the ability to locate hard-to-borrow shares and the cost of doing so matters more than commissions. Retail apps typically offer neither.

Margin rates

Intraday margin is standard, but overnight margin rates vary by several percentage points between brokers, which compounds fast on a carried position.

Platform stability under loadEssential

The measure that no rate card shows: whether the application stays responsive on a high-volatility open. Worth more than any fee difference on the days it matters.

Pricing

TradeStation, Lightspeed, Webull and Robinhood publish rate cards. Interactive Brokers publishes two schedules: commission-free US stock and ETF trading on IBKR Lite, and tiered per-share pricing on IBKR Pro. Lightspeed also offers customised pricing on request, and its published rates apply to accounts opened after 1 March 2024.

The cheapest credible entry is Webull, with zero commission on US-listed stocks and ETFs and no deposit minimum. Robinhood is commission-free on stocks, ETFs and options, then $0.04 per options contract. Costs jump when you add direct routing ($0.0032 to $0.0048 per share on TradeStation) or Lightspeed's $0.25 per-trade minimum below 249,999 shares.

TradeStation's desktop is included for brokerage clients and costs $99.99/month ($199.99 professional) only if you use it without an account.

Mistakes to avoid

×Planning around the wrong day trading rule. FINRA replaced the pattern day trader equity minimum and its trade count with intraday margin requirements effective June 4, 2026, but brokers may keep the old rule until October 20, 2027. Ask your broker which regime your account runs on before you plan around commissions.

×Comparing commissions and forgetting the fixed costs. Market data, routing fees and any platform subscription land on every statement, and TradeStation charges $99.99/month for its desktop if you use it without a brokerage account. At low volume, a free platform with slightly worse fills is straightforwardly cheaper.

×Choosing a pricing schedule that fights your style. At 300 trades a month of 100 shares each, per-trade pricing at $3.50 costs roughly $1,050 while per-share at $0.0035 costs about $105. Traders routinely pick the wrong one and never check.

Expert tips

→Paper trade on the platform you intend to use, not a different one. Hotkeys, order tickets and the way a platform behaves on a fast open are muscle memory, and switching after you go live is how avoidable mistakes happen.

→Ask about short locates before funding an account if shorting is part of your plan. Borrow availability and locate fees vary enormously, and a strategy that depends on shorting small caps is not viable on a platform without inventory.

→Recalculate your tier every quarter. Both TradeStation and Lightspeed price by monthly volume, so a change in your activity can move you a tier in either direction, and nobody will tell you that you are now overpaying.

The bottom line

If you are trading seriously and at size, Interactive Brokers is still the answer, on execution, global access and margin rates, provided you accept the learning curve.

TradeStation is the best balance for most active traders who want a professional platform and a rate card they can actually calculate, and its desktop platform comes with the brokerage account. Lightspeed is the specialist choice once your costs are measured per share rather than per trade.

And if you are starting out, start on Webull: no commissions, no minimum, real charting, and a paper trading mode where the first few months belong. Robinhood will get you trading fastest, which is not the same as trading well.

Before any of it, ask your broker whether it has moved to FINRA's new intraday margin rules or still applies the old pattern day trader minimum, which firms may keep until October 20, 2027.

Frequently asked questions

What happened to the $25,000 pattern day trader rule?

FINRA replaced it. From June 4, 2026, amended Rule 4210 drops the $25,000 minimum equity and the four-trades-in-five-days designation, and instead requires your margin account to hold enough equity during the trading day for the positions you actually carry. Brokers may phase the change in until October 20, 2027, so some accounts still run on the old rule. You still need $2,000 in equity to trade on margin at all.

Is per-share or per-trade pricing cheaper?

It depends entirely on your average order size. Per-share pricing is cheaper when you place fewer, larger orders; per-trade is cheaper when you place many small ones. Using Lightspeed's published rates, 300 monthly trades of 100 shares costs about $105 on per-share at $0.0035 and about $1,050 on per-trade at $3.50. At 5,000 shares per trade the comparison inverts. Run your own numbers, because the gap is an order of magnitude, not a rounding error.

Do I need a paid platform, or is a free app enough?

A free app is enough to learn on and to trade a handful of times a day. You are paying for a professional platform to get routing control, reliable Level 2 depth and stability on volatile opens, which only start paying for themselves at real frequency. TradeStation includes its desktop with a brokerage account, so the real question is whether your volume justifies the routing and data costs, not a subscription.

Does commission-free trading mean it is actually free?

No. Commission-free means no per-trade commission; you can still pay per-share clearing, routing fees, options contract fees, regulatory pass-throughs, platform subscriptions, market data and borrow costs on shorts. TradeStation advertises $0 commissions and charges $0.003 per share of clearing on its entry tier. Read the full schedule, not the headline.
