Quantower vs Sierra Chart
Modern, multi-broker, sometimes free. Or old, fast, and yours.
Quantower is the modern challenger: a clean multi-broker terminal that connects to 60+ brokers and data feeds, has a genuinely usable free tier, and is even free through some brokers like AMP or Optimus. Sierra Chart is the incumbent, dated, Windows-only, and famously deep, with one thing Quantower does not give you: raw tick data on disk that you own. Both automate in code, so for a builder the fork is interface and broker-flexibility versus data ownership and speed.
The bottom line
Quantower wins on interface, multi-broker flexibility, and cost (free through some brokers); Sierra Chart wins on speed and raw tick data you own. Pick Quantower for a modern, broker-neutral seat; pick Sierra Chart when owning your data and building a pipeline on it is the point.
Feature by feature
| Feature | Quantower | Sierra Chart |
|---|---|---|
| Interface / ease | Modern, clean, multi-broker | Powerful but dated, steep |
| Broker / feed flexibility | 60+ connections; multiple brokers at once | Fewer: Teton/Rithmic/CQG/Denali |
| Cost | Free tier; full ~$70/mo; free through some brokers | ~$46/mo order-flow package + data |
| Order flow | Footprint, DOM, volume profile (paid tiers) | Native, fast, deep |
| Automation | C# strategy API + backtesting (code, no visual builder) | ACSIL (C++) / DTC + your own bridge |
| Raw tick data you own | Streams via feed, not a tick archive you keep | .scid tick files on disk + 10+ years of Denali history |
| Data history depth | Feed-dependent | Denali 10+ years |
| AI / Claude Code pipeline | No owned tick archive to hand off | Reads .scid in Python; Claude Code backtests on real ticks |
FAQ
Is Quantower or Sierra Chart better?
Quantower is easier, more modern, and broker-neutral with a free tier; Sierra Chart is faster, deeper, and hands you raw tick data you own. For most people Quantower is the comfier seat; for builders who want an owned data pipeline, Sierra Chart wins.
Is Quantower really free?
There is a genuinely usable free tier (basic charting plus execution), and Quantower is fully free through some brokers like AMP Futures via Optimus Flow. Order-flow tools (footprint, volume profile) need a paid tier (about $70/mo) or a broker that bundles them. Market data is separate either way.
Can you automate on Quantower?
Yes, it has a C# strategy API with backtesting, though no visual builder, so you write code. That is similar in spirit to Sierra Chart, which uses C++ ACSIL or external bridges. Both are code-first platforms.
Does Quantower give you your raw tick data?
Not the way Sierra Chart does. Quantower streams data from your feed, but Sierra Chart stores tick data as .scid files on disk that you own and can pull into your own tools: the basis for a fills-honest backtest and for Claude Code reading it in Python.
Should I switch from Quantower to Sierra Chart?
Only if owning your data and building a research pipeline outside the platform is the goal. If you want a modern, flexible, low-cost seat to trade from, Quantower is excellent. Sierra Chart rewards the builder who needs the raw material.
