Mirror trades from one leader account to as many followers as you need, across as many prop firms as you trade — on the same machine, across your local network, or anywhere through the secure cloud relay. Scale-aware (follower contracts proportional to size), reconciles when a mirror drifts, suppresses duplicate fills, journals every leg for the eval reviewer.
Trade your leader once — the copier mirrors every fill to your followers: on the same machine, across your LAN, or anywhere through the cloud relay.
Build a group, map your accounts, and watch a leader fill mirror to every follower in real time — start to finish.
Most prop-firm traders run the same strategy on multiple firm accounts at once. Trying to do that manually is how you end up with one account at +3 contracts, another at flat, and a mismatched fill you didn't notice for an hour. The Copier mirrors every fill, every cancel, every modify in real time — across every account in the group.
Every fill on the leader account fires a mirrored order on each follower the moment it happens. Cancels, modifies, position closes — all replicated. The follower fills come back, the Copier reconciles them against the expected mirror, alerts on drift.
Each follower has its own contract scale. Leader takes 3 NQ → small follower mirrors 1, medium mirrors 2, big mirrors 5. Configure per follower, per group. Risk-tier accounts stay small, full-size accounts stay full size, automatic.
If a follower fill comes back at a different price, or a follower's position drifts out-of-sync (OOS) with the leader, the reconciler detects it and either auto-corrects (configurable) or surfaces it in the Activity tab with one-click correction.
Every order, every fill, every cancel logged with timestamps to a local journal file. When the eval reviewer asks "what happened at 10:42:13," you have the answer with per-account granularity. All local — nothing leaves your machine.
Strategy fires a duplicate order during a recompile? Late-fire cancel after an exit? The Copier has built-in suppression rules for known NT8 quirks so followers don't mirror noise the leader doesn't mean to send.
One group = one leader + N followers. Run multiple groups in parallel — different strategy on each firm, a different set of followers per group. Tabs across the top, just like checklists or focus groups in our other AddOns.
Your $50K eval account and your $150K live account shouldn't take the same contract count. The Copier handles that out of the box. Each follower has its own scale; the leader trade fires the right size on each.
A network blip, a partial fill, a price slip on one follower — and now your accounts aren't in sync. Manually, you might not notice until end of day. The reconciler watches every fill and flags any follower that drifts from the expected mirror.
Configurable response per group: auto-correct (close the OOS position, restore the mirror), or surface in Activity with a one-click corrective trade. Either way, the issue gets seen immediately, not at EOD.
The full copy engine — scale-aware sizing, drift reconciliation, per-leg journaling — is in every tier. What changes is reach: how many follower accounts, and whether you copy on one machine, across your local network, or anywhere through the secure cloud relay. One-time pricing — no subscription.
All NinjaTrader 8 updates are free for the life of the product. If/when NinjaTrader 9 is released and the port requires significant rework, a small upgrade fee may apply — expect nominal, not a fresh purchase.
Yes — NinjaTrader 8 only. Install like any other NT8 add-on: Control Center → Tools → Import → NinjaScript Add-On → pick the zip. NT auto-installs and recompiles. NT7 and other platforms are not supported.
Unlimited per group, unlimited groups. Common setups: one group per strategy with one leader and 3-6 followers across firms; or one group per firm if you run different strategies on each. Each group is fully independent.
Each follower has its own contract scale (ratio or absolute number). Leader takes 3 NQ → follower with scale 0.33× takes 1, scale 1.0× takes 3, scale 1.67× takes 5. Round-up or round-down policy is per-follower.
The reconciler detects it within seconds. Configurable response per group: (1) auto- correct — Copier closes the OOS position and restores the mirror; (2) flag-only — surface in the Activity tab with one-click corrective trade. Either way, new copies are suppressed for that follower until it's back in sync.
Yes — the Copier doesn't care which firm an account belongs to as long as NinjaTrader can route orders to it. Apex / TopstepX / Bulenox / Tradeify / FastTrack / your live cash account — all valid as leader or follower, in any combination.
Yes. The leader can be a manually-traded account, a NinjaScript strategy on an account, or an account being traded from a third-party signal. The Copier hooks NT's order/ execution events at the account level, so the source of the leader's orders doesn't matter.
A standard NinjaScript Archive (.zip). Compiled, not source. The zip includes the MDT
AddOn Framework runtime — install once, reused by every other MDT AddOn (Focus Manager,
Checklist).
When a new version is released, the new zip appears in your Customer Dashboard Downloads tab. Re-import in NinjaTrader (Control Center → Tools → Import → NinjaScript Add-On). Your account mappings, groups, and settings all carry over — they’re saved outside the AddOn, so an update never resets them. More detail in the Docs.

Set the leader. Set the followers. The Copier handles the rest — every fill, every cancel, every modify, copied to every follower in real time.
