Bias disclosure first: we make Trading Floor, one of the tools below. We'd rather earn your trust with an accurate map than pretend to be neutral — every competitor fact is dated, their strengths are stated, and the criteria come before the contenders.
| Copier | Model | Price | Strongest when |
|---|---|---|---|
| Trading Floor (us) | Cloud; browser + iOS | $25–50/mo, first month free | Multi-firm floors on Tradovate/NT-brokerage/TopstepX/Rithmic/Volumetrica; you want per-order latency receipts (published live) and auto-flatten guardians |
| TradeCopia | Desktop app or hosted web/VPS | $49.99–$149.99/mo | You trade from Quantower/ATAS/Sierra Chart, or need unlimited accounts — our comparison |
| Replikanto | NinjaTrader 8 add-on | $0–$399 one-time + credits | NT8-only floors on machines you already keep running — our comparison |
| Other NT8 add-ons / platform-native tools | In-platform | varies | Single-platform floors with simple needs; verify support and rule-compliance features carefully |
If everything you run lives in NinjaTrader 8 and you like one-time pricing: Replikanto, and we mean that. If you trade from Quantower/ATAS/Sierra: TradeCopia. If your floor spans prop firms and platforms — which is most funded traders in 2026, now that ProjectX is Topstep-exclusive and firms split across Tradovate, Rithmic and Volumetrica stacks — a cloud copier with direct API connections is the architecture that matches your life, and we built Trading Floor to be the most verifiable one: measured per order, published at /latency, guardians on by design.
It depends on where your accounts live. For floors spanning Tradovate, NinjaTrader-brokerage, TopstepX, Rithmic and Volumetrica, cloud API copiers fit best — Trading Floor mirrors at ~42ms median with per-order latency published live. For NT8-only setups, Replikanto (an NT8 add-on with one-time pricing) is strong; for Quantower/ATAS/Sierra Chart routes, TradeCopia covers the most platforms.
Four things: direct support for the platforms your accounts actually run on; whose uptime the copies depend on (your machine vs the cloud); verifiable per-order latency, since copy delay is slippage on every follower; and risk controls that auto-flatten before a firm's drawdown or daily-loss number is hit.
Most major futures prop firms allow trade copying across your own accounts, often with conditions — some restrict copying between different firms or third-party accounts. Always verify your firm's current rules in their official documentation before copying.
