Most active traders shopping for a direct access platform end up choosing between these two. Both are broker-agnostic software you license through a direct access broker, not standalone brokerages themselves.
Past that surface similarity, they diverge in ways that actually affect your trading day.
Platform vs Broker (Same Setup, Different Owners)
Neither DAS Trader Pro nor Sterling Trader Pro is a broker. Both are white-label software licensed to direct access brokers, who then set the price and bundle it with their own execution and data feeds.
That means the same platform can cost differently, or behave slightly differently, depending on which broker you access it through. Some brokers, like Lightspeed, even offer both DAS and Sterling as third-party options alongside their own in-house platform, so you're not locked into one software vendor just because you picked a broker.
Pricing
DAS Trader Pro: platform fees run $25 to $150/month depending on broker, before data packages. Most brokers waive the fee entirely once you clear a volume threshold, typically 200,000 to 250,000 shares/month, though it works more like a cliff than a gradual discount.
Sterling Trader Pro: typically runs $100 to $300/month, with most brokers landing in the $120 to $200 range. Cobra Trading charges $200/month plus $30 for add-ons. Most Sterling brokers waive the fee above 300,000 shares/month traded, a higher bar than DAS's typical threshold.
One exception worth knowing: Capital Markets Elite Group offers Sterling Trader Pro for $99/month, dropping to free once you generate $499 or more in monthly commissions, closer to DAS's commission-based waiver model than Sterling's usual share-count cliff.
Interestingly, Lightspeed itself charges $230 to $260/month if you want Sterling Trader Pro through them, notably more than their own in-house Lightspeed Trader Pro at $130/month. If you're choosing Sterling specifically, which broker you route it through matters as much as the platform choice itself.
Bottom line on cost: Sterling's typical floor ($100 to $300) runs higher than DAS's ($25 to $150), and its volume waiver requires trading more shares to hit ($300k vs ~200-250k). If cost is the deciding factor and you're not yet at high volume, DAS brokers generally have the lower entry point.
Speed, Execution and API Access
In our own hands-on testing with both platforms, DAS Trader Pro feels faster. Order fills come back quicker, and it holds up better under fast-moving conditions like open drive or a halt resume. It's not a night-and-day gap, but it's noticeable to anyone who's traded both side by side for a stretch.
Sterling isn't slow. Independent reviews rate its execution as solid and reliable for most discretionary trading. But DAS's infrastructure has more headroom under it, DAS runs on its own low-latency backend and connects to 100+ routing destinations versus Sterling's shorter list, and that headroom is part of why it edges out Sterling when things get fast.
The one place the gap becomes structural rather than a feel-difference: if you're running any kind of automated or algo strategy through the platform's API, Sterling's throughput cap becomes a real constraint that DAS doesn't share.
For most traders clicking buttons manually, DAS's speed edge is real but modest, worth knowing, not worth switching brokers over on its own.
Charting
This is where Sterling consistently pulls ahead across independent reviews, not just DAS's own marketing.
Sterling Trader Pro supports multicharts (multiple charts visible at once across different timeframes or symbols) and more customizable layouts. Reviewers who've used both platforms extensively note Sterling's charting as the stronger of the two, even though DAS also offers 30+ chart types with indicators and drawing tools.
Neither platform's charting rivals dedicated tools like TradingView or TC2000. If charting quality is a top priority, both are a step down from a standalone charting subscription layered on top.
Where Each One Falls Short
Sterling's scanner is close to unusable. It offers only a handful of filters (52-week high/low, day high/low) and most active reviewers recommend pairing Sterling with a dedicated scanner like Trade Ideas rather than relying on its built-in tool.
Sterling requires a separate subscription per brokerage account. If you trade through two different brokers, you need two separate Sterling subscriptions, they don't link. DAS doesn't carry this same restriction structure.
Both are built for very active traders. Sterling in particular is designed for traders moving hundreds of thousands of shares per month; if you're a swing trader or lower-volume options/futures trader, the monthly fee on either platform is hard to justify against the value you'd actually use.
Who Wins on What
Speed: DAS. Our personal testing found DAS faster on fills and general platform responsiveness, especially under fast-moving conditions like open drive or a halt resume.
Lower cost at lower volume: DAS. Platform fees start lower and the waiver threshold is easier to clear.
Algo/API trading: DAS, by a clear margin. Sterling's 5-orders-per-second cap is a hard ceiling; DAS's API has none.
Charting quality: Sterling, according to independent reviewers who've used both extensively.
Multi-broker flexibility: DAS. Sterling ties each subscription to a single brokerage account.
Built-in scanning: Neither is strong, but DAS's scanner is generally considered more usable than Sterling's near-nonfunctional filter set.
Best for extremely high share volume: Sterling. It's purpose-built for traders and institutions moving several hundred thousand shares a month, with pricing and waivers structured around that level of activity.
Bottom Line
If you're API-trading, running custom automation, or want the lower-cost entry point while you build up volume, DAS Trader Pro is the more practical choice for most individual active traders.
If you're already trading serious share volume, want stronger native charting, and don't need to link multiple brokerage accounts under one subscription, Sterling Trader Pro is worth the higher price floor.
Either way, check DAS Trader Pro's cost by broker before committing. The platform fee is only part of the bill, and which broker you pick decides the rest.
