The Core Difference: Platform vs. Broker
This is the part that trips people up first.
DAS Trader is a platform you bolt onto a broker. Interactive Brokers, CenterPoint, SpeedTrader, Cobra, and others all support it. You pay the platform fee on top of your broker's commissions.
Lightspeed is the broker itself. Lightspeed Trader Pro is its in-house platform. You don't need to shop for a compatible broker because the two are the same account.
That single structural difference decides a lot of what follows: pricing, support, and how much choice you have over execution routing.
Pricing Side by Side
DAS Trader
Platform fees run $25 to $150/month depending on broker, before data. Interactive Brokers charges $100/month flat regardless of volume, the one broker on this list that never waives it.
Every other major DAS broker drops the fee to $0 at a volume threshold, but it's a cliff, not a gradual discount. You either clear the line or you pay the full fee that month.
SpeedTrader: $25 to $104/month base, waived entirely above $499 in monthly commissions.
CenterPoint Securities: $120/month, waived above 250,000 shares (or 1,000 options contracts) traded that month.
Cobra Trading: roughly $125/month, waived above 200,000 shares/month.
Add a data package (typically $18 to $68/month) and most active retail traders land at $100 to $200/month all-in, before any volume waiver kicks in.
Lightspeed
The flagship Lightspeed Trader Pro carries a $130/month platform fee. But unlike DAS's broker waivers, Lightspeed's fee reduces continuously with your trading activity.
Your monthly commissions are subtracted directly from the $130 fee, dollar for dollar, down to a $0 floor. Generate $80 in commissions and you owe $50 that month. Generate $130 or more and the platform fee disappears entirely, no threshold required.
Separately, accounts under $15,000 in equity carry a $25/month minimum commission charge, only billed if your actual commissions don't already reach $25. This isn't stacked on top of the platform fee. It's a floor on the commission side for smaller accounts.
Per-share pricing starts around $0.0035 to $0.0045 for under 250,000 shares/month and drops from there, separate from the platform fee math above.
The real difference isn't the dollar figure. It's the mechanic.
DAS brokers (outside Interactive Brokers) work on a cliff: hit the share or commission threshold and the fee vanishes, miss it by one trade and you pay the full amount. Lightspeed works on a continuous offset: every dollar of commission chips away at the fee, so moderate-volume traders get partial relief instead of an all-or-nothing outcome.
Verdict on cost
Both platforms can hit $0/month in platform fees at sufficient volume. The question isn't which one is cheaper on paper. It's which fee structure matches how you actually trade.
If your volume is inconsistent month to month, Lightspeed's gradual offset is more forgiving. A slightly light month still earns you a partial discount. If you trade in a way where you reliably clear a hard threshold (or reliably don't), DAS's cliff model is simpler to plan around, and brokers like SpeedTrader have one of the lowest entry points on this list for traders not yet at volume.

Execution and Routing
Both platforms are built for the same job: get an order filled in under a second with minimal slippage.
Lightspeed Trader Pro routes to over 100 destinations including exchanges, ECNs, dark pools, and market makers, with multi-threaded processing across pre-market, core, and overnight sessions.
DAS Trader Pro executes through a comparably fast, low-latency network with direct market access and the same session flexibility.
Neither platform has a clear execution-speed edge worth the debate. Both are fast enough that your fills won't be the bottleneck.
The real difference shows up in the extras. Lightspeed's short-locate system across multiple providers is generally regarded as more intuitive than the version bundled into most DAS-compatible brokers.
Lightspeed's newer Pro release also adds an AI chat tool for scanning and fundamental-data queries that DAS doesn't have an equivalent for.
Charting: The Gap That Actually Matters
This is where the two platforms diverge hardest, and it's underreported in most reviews.
DAS Trader's charting is functional but dated. One long-time reviewer described DAS's charts as "stuck in the 80s or 90s" next to Lightspeed's cleaner, more modern interface.
If you rely on charts for entries rather than just tape-reading Level 2, this is a real point in Lightspeed's favor, not a cosmetic one.
Who Wins on What
Lowest true floor: both platforms can reach $0/month in platform fees at volume. DAS's waiver is a cliff (clear the threshold or pay in full), Lightspeed's is a continuous offset (partial credit at partial volume).
Cleanest fee structure for inconsistent traders: Lightspeed. The dollar-for-dollar commission offset means a slow month still lowers your bill, instead of an all-or-nothing outcome.
Cleaner charting and UI: Lightspeed, by a wide margin.
Broker flexibility: DAS. You choose the broker and shop pricing. Lightspeed locks platform and execution into one account.
Short locate: Lightspeed's system is the more intuitive of the two.
Educational resources for beginners: neither is really built for this, but Lightspeed's broader materials give it a slight edge over DAS's near-total absence of onboarding content.
Bottom Line
Neither platform is "better" in the abstract. They answer different questions.
If you already have (or want) a specific broker relationship and want to control platform cost independently, DAS Trader gives you that flexibility, and a broker like SpeedTrader gives you one of the lowest entry costs on this list.
If you'd rather have the platform and execution bundled into one account, with modern charting and a fee that scales down gradually instead of on a cliff, Lightspeed is the tighter package.
Either way, the platform is only half the decision. The other half is whether the execution speed and fee structure you're paying for are actually showing up in your win rate. That's a question neither DAS nor Lightspeed's dashboard will answer for you.
