TradeDupe vs TradeSyncer: Which Trade Copier Is Right for You?

Price at the same connection count. TradeSyncer Basic and TradeDupe Standard both give you 2 broker logins with 10 accounts each; TradeSyncer charges $49, TradeDupe $30. At 4 logins it is $99 against $60. At unlimited, $149 against $120. Yearly, $34 / $69 / $104 against $20 / $45 / $90. There is no per-account surcharge inside a tier on either product.

Documented follower controls. Each TradeDupe follower has an on/off toggle, a whole-number multiplier and an allowed-contract list. A fill on a follower that the copier did not place — a manual click in the Tradovate app, a stale bracket leg — is market-closed automatically, which is what stops one account ending up hedged against the rest (this does not cover followers on the same Tradovate login as the leader). TradeSyncer advertises 'Follower Account Protection' and per-account loss limits and lockouts, but does not describe a per-follower toggle or an automatic close of unauthorized fills.

Authorization. TradeDupe connections are authorized through Tradovate's OAuth flow; TradeDupe never sees your password. TradeSyncer says accounts are 'connected via encrypted APIs' and does not state whether it uses OAuth.

• $30 / $60 / $120 vs $49 / $99 / $149 at identical connection gating.
• Per-follower toggle, multiplier and allowed-contract list.
• Rogue-fill auto-close for followers on a different login than the leader.
• Tradovate OAuth — TradeDupe never sees your password.

Platforms. TradeSyncer's homepage lists TradingView, NinjaTrader, Tradovate, Rithmic, dxFeed, Sierra Chart, ATAS, Quantower and ProjectX, with Hyperprop marked 'Soon'. If one account in your stack is on Rithmic or NinjaTrader, TradeDupe cannot copy to or from it — full stop.

Multiplier flexibility and prop tooling. TradeSyncer documents mini-to-micro mapping on its multipliers, per-account daily loss limits, profit triggers and session lockouts, a prop firm tracker and real-time error alerts, and ships native Windows, macOS, iOS and Android apps. TradeDupe multipliers are whole numbers only, and its risk limits are written to Tradovate's own auto-liquidation settings rather than enforced in the copier.

Its help center advertises an average copy speed of 20–40 ms. We do not publish a latency figure; TradeDupe's worker reacts to Tradovate's execution-report stream rather than polling, and you can watch each follower result in the live feed during your trial.

• Any account on NinjaTrader, Rithmic, ProjectX, Sierra Chart, ATAS or Quantower.
• You want TradingView webhook-driven orders copied.
• You use its prop firm tracker or mobile apps daily.
• Your current TradeSyncer setup works and migration isn't worth the saving.

From help.tradesyncer.com (October 2026): no multi-bracket ATM strategies, no stop-limit orders, no automated trailing stops (manual trailing is fine), dragging stop orders on the chart is unsupported, and open P&L displays only for NQ, ES, CL, GC, SI, YM, RTY and their micros. TradeDupe mirrors leader bracket modifications — including a dragged stop — to follower legs; it does not place trailing stops either.

Both products have a 7-day trial with a card on file. TradeSyncer charges on day 7; TradeDupe on day 8. TradeSyncer's refund line: 'No refunds are issued for past payments after cancellation unless Tradesyncer decides differently.' TradeDupe refunds within 24 hours of the initial purchase only.

Start the TradeDupe trial while TradeSyncer is still active. Authorize your Tradovate login via OAuth, mark the leader, toggle on followers, set each follower's multiplier and allowed contracts. Both copiers can read the same Tradovate login during the trial, so run one session on the same leader and compare fills and bracket updates in TradeDupe's live feed. Then disable followers in TradeSyncer the same day — never leave both copying the same followers — and cancel from Settings > Subscriptions > Cancel Subscription before the next renewal.

• Both copiers can read the same Tradovate login during a trial.
• Compare one live session, then disable followers in TradeSyncer.
• Cancel at Settings > Subscriptions; access runs to the period end.
