Replikanto

Replikanto is a trade copier that runs inside NinjaTrader 8. It watches one account, the leader, and repeats its orders on other accounts, the followers: in the same NinjaTrader, on another computer on your local network or, with paid credits, on a computer anywhere over the internet. It’s made by FlowBots. This review is based on FlowBots’ product page, store, terms and help centre, checked on 18 October 2026. We haven’t tested Replikanto ourselves, so it doesn’t assess copy speed, reliability or how often followers match the leader.

What Replikanto is

Replikanto is a NinjaTrader 8 add-on. It needs NinjaTrader 8.1.6 or later, and 8.1.7 or later to copy between Playback accounts. FlowBots supports it on Windows only; on a Mac it can run in a Windows virtual machine, which FlowBots doesn’t help set up.

It copies orders placed through NinjaTrader’s Chart Trader and SuperDOM, ATM strategies and OCO brackets, with market, limit, stop market, stop limit and MIT orders. When the leader is a Tradovate account, FlowBots says orders placed in Tradovate’s web or mobile apps or in TradingView are copied too. Accounts can be on Rithmic (including prop-firm accounts on Rithmic), Tradovate, Interactive Brokers, other connections NinjaTrader supports, and Sim or Playback.

A local add-on, not a cloud copier

The main decision is where the copier runs. Tradesyncer runs in the cloud: it connects to each broker account directly, and copying doesn’t depend on the trader’s own computer. Replikanto runs inside NinjaTrader. NinjaTrader and Replikanto have to be running on every computer involved, and every computer needs its own licence.

That trade-off works both ways. Copying between accounts connected in one NinjaTrader on one computer needs a single licence and no internet relay, and the lifetime licence is a one-time purchase, although updates after the first year need a paid extension. But if that computer, NinjaTrader or a broker connection stops, copying stops with it. Traders who already use NinjaTrader and want followers to run the same ATM strategies are the natural fit; traders who don’t use NinjaTrader aren’t.

Same computer, local network or internet

Replikanto has three ways to reach followers:

• Same computer. Leader and followers are accounts in one NinjaTrader. One licence covers them.
• Local network. Followers run in NinjaTrader on another computer on the same network, each computer with its own licence. No credits are used.
• Internet. Followers run on a computer anywhere, such as a VPS. Trades go through FlowBots’ servers. Every computer needs a valid licence and a signed NinjaTrader Machine ID, and the leader needs Submit credits.

For internet copying, FlowBots’ documentation adds some conditions:

• A leader on NinjaTrader’s Simulated Data Feed or Playback connection never sends trades to remote followers; those trades reach only followers on the leader’s own computer. Followers can use Sim accounts on any connection.
• FlowBots advises keeping the leader and every remote follower on the same Replikanto version. A fix in version 1.7.0.0 for a remote follower that could hold back the leader’s next trade applies only once the follower runs 1.7.0.0 or later.
• From version 1.7.0.0, if the connection to FlowBots’ server drops, Replikanto keeps trying to reconnect on its own. No trades are copied over the internet while it’s disconnected. If it gives up, the follower has to switch Remote Node Mode off and on again, or restart NinjaTrader. Before 1.7.0.0, a single connection error could switch Remote Node Mode off without warning.

For remote copying, FlowBots also says copying is paused during internet or broker disruptions, and that it doesn’t guarantee followers stay in sync with the leader.

What the leader can’t see on internet followers

This is the biggest practical limit of copying over the internet. FlowBots’ guide to remote copy trading says the leader “cannot directly monitor the remote followers’ setups, accounts, positions, or open orders”, because remote followers don’t receive the leader’s positions or working orders, and that some Follower Guard actions don’t work in remote mode. FlowBots places the responsibility for checking that follower positions are closed and orders cancelled on the leader, and suggests messaging remote followers directly. The documentation we reviewed doesn’t say whether these limits also apply to followers on a local network.

For both local network and internet followers, the leader’s Replikanto shows each other computer only as on, off or away. A computer is shown as away when it didn’t receive a trade or returned an error. For internet followers that are away, FlowBots suggests switching them off until the problem is fixed, so that credits aren’t spent on copies that aren’t delivered. FlowBots also says the leader can’t rearm follower accounts on a remote Replikanto; that has to be done on the follower’s own computer.

ATM Copy vs copying the leader’s exit orders

Each follower has an ATM Copy setting, and it changes how exits work:

• ATM Copy on. Replikanto copies the entry and tells the follower to run the leader’s ATM strategy, so NinjaTrader places that follower’s stop and target itself. The strategy must exist with the same name and the same settings in every NinjaTrader involved; FlowBots calls a mismatch the most common reason ATM Copy misbehaves. NinjaTrader splits the follower’s contracts across targets and puts any remainder on the first target. From version 1.7.0.0, each follower’s ATM stop and target use their own OCO group, so a fill on another account doesn’t cancel them.
• ATM Copy off. Replikanto copies the leader’s exit orders to the follower. With a ratio, each target is scaled on its own: a leader’s 1/1/1 copied at a ratio of 3 becomes 3/3/3.

FlowBots documents several limits:

• ATM Copy applies only to trades placed in NinjaTrader Desktop with an ATM strategy. Trades placed elsewhere are copied with the leader’s exit orders, even with ATM Copy on.
• Followers can’t use a different ATM strategy from the leader’s.
• An ATM strategy applied to an already open position isn’t copied.
• A Custom Stop Strategy doesn’t account for a follower’s scaled quantity, so FlowBots advises a regular stop loss when copying at a ratio other than 1.
• NinjaTrader’s “Use server side ATMs” option has to be off, because NinjaTrader ignores ATM strategies started by add-ons while it’s on.

If NinjaTrader can’t start a follower’s ATM strategy, the follower doesn’t copy that entry. From version 1.7.1.0, if NinjaTrader had already sent the follower’s entry, Replikanto tries to cancel it rather than leave it without a stop and target; cancellation isn’t guaranteed. If the entry filled fully or partly before it could be cancelled, or NinjaTrader refused to cancel it, the follower can be left holding a position that no ATM strategy manages. Replikanto doesn’t close that position: the trader has to check it and protect or close it.

Sizing and Cross Order

Replikanto has seven copy methods: Exact Quantity, Pooled Quantity, Ratio, Pre Allocation, Net Liquidation, Available Cash and Pct Change. FlowBots describes the last three as methods for stock accounts. Cross Order lets a follower trade a different size of the same product, such as MES when the leader trades ES; FlowBots’ default map covers 36 futures families. Market Only copies only the leader’s fills, as market orders, so remote followers can fill at a different price from the leader.

The copy method also affects when a follower counts as out of sync. From version 1.7.0.0, exact methods must match exactly, while methods that round each entry down tolerate a small shortfall. A Pct Change follower is never marked out of sync, so neither of Follower Guard’s flatten timers ever acts on it.

Follower Guard: optional, delayed protections

Follower Guard watches followers and can act when they drift from the leader. A follower that’s out of sync is marked in yellow but keeps receiving trades. Its actions are optional and work after a delay you set:

• Cancel an unfilled follower entry after the leader’s entry fills (5 seconds by default), together with the stop and target copied for it. A partly filled entry is left working.
• Flatten a follower that stays out of sync (10 seconds by default). Each new fill on the follower restarts the countdown, and it only acts if the follower is still out of sync.
• Flatten a follower on the opposite side from the leader (5 seconds by default, from version 1.5.3). A quantity difference alone doesn’t trigger it.
• Flatten a follower after an order error, such as a broker rejection or a failed submission (3 seconds by default), with five separate options.

FlowBots’ documentation states that the two timed flatten options, out of sync and opposite side, are off by default. After any of these actions, Replikanto can disarm the follower so it stops copying until it’s rearmed, and show a message. It can also send an e-mail when a follower is disarmed, but only once NinjaTrader is set up to send e-mail: an alert address in NinjaTrader’s general options and a mail account under Share Services. Automatic disarming can be switched off.

On connections other than Rithmic, from version 1.7.1.0, the two timed flatten options first wait for NinjaTrader to finish applying the follower’s latest fills, for up to about 30 seconds. If NinjaTrader still hasn’t caught up, Follower Guard acts on the position NinjaTrader shows and logs a warning asking the trader to check the follower. Before 1.7.1.0, a follower on a connection that applies fills late, such as Tradovate, could be flattened on an out-of-date position.

These protections react after the fact. They can’t stop a broker rejecting an order, and FlowBots asks traders to check accounts after Follower Guard acts.

Rithmic position re-read

FlowBots documents a problem where NinjaTrader keeps showing a Rithmic account in a position the broker has already closed, or misses a fill. In that case, flattening the “phantom” position can open a real trade in the opposite direction. FlowBots attributes this to how Rithmic delivers position updates; we haven’t verified that explanation.

From version 1.7.0.0, with the setting on, Replikanto asks Rithmic for the account’s real position before it flattens a follower, whether through Flatten All, a follower’s Flatten button, a Close copied from the leader or Follower Guard. It also checks about a second after a fill with no position update. The setting is on by default.

FlowBots documents its limits:

• If Rithmic doesn’t answer within 750 ms, the flatten goes ahead with the position NinjaTrader shows, and the Log tab records a warning.
• It runs only while a Replikanto window is open.
• With Flatten All, the leader account itself isn’t re-read first.
• NinjaTrader’s own Flatten Everything and Chart Trader or SuperDOM close buttons don’t get the re-read.
• Followers on another computer are re-read by the Replikanto on that computer, which also needs version 1.7.0.0 or later.
• Version 1.7.0.1 fixed two problems in 1.7.0.0: with many Rithmic followers, re-reads for a copied Close could time out on every follower, and after a broker reconnection the re-read could stop for that account until the next connection event.

FlowBots’ advice is to treat the position shown in RTrader Pro as the real one when the two disagree.

Licences, credits, refunds and terms

Replikanto is sold per computer, with a lifetime or a one-year licence. On 18 October 2026 the store showed these as sale prices, in US dollars, with no end date given:

• Single Machine, lifetime: $299 (regular $399).
• 2 Machines, lifetime: $399 (regular $499).
• Single Machine, 1 year: $249 (regular $349).
• 2 Machines, 1 year: $299 (regular $399).
• Each additional machine: $100 lifetime (regular $200) or $50 for a year (regular $100).

Licence length and support are separate. Every licence includes one year of support and updates, which can be extended yearly. After that year, a lifetime licence keeps working, but new versions are included only while support and updates are active. A one-year licence stops working when it expires unless it’s renewed. We did not find an extension price in the official pages reviewed.

Internet copying uses Submit credits. FlowBots’ help centre states that users receive 20 initial testing credits, and packs range from 100 credits for $15 to 1,000,000 for $5,000. Only the leader pays: a credit is used for each order transmitted with a “Submitted” state, for each remote computer it’s sent to, while changes and cancellations are free. Local network and same-computer copying use no credits. Credits can’t be moved to another person. When they run out, nothing is sent over the internet. FlowBots doesn’t say how credits are counted when one remote computer runs several follower accounts, or whether credits expire.

The trial lasts 7 days with all features and 20 credits, and FlowBots recommends testing on Sim accounts first. Under FlowBots’ terms, a purchase can be refunded in full within 14 calendar days, once per product per person; renewals and support extensions aren’t refundable. The terms provide the software “AS IS” and cap FlowBots’ liability at the fees paid. They don’t name a legal entity, a governing law or a date.

Copying and your prop firm’s rules

FlowBots notes that some prop firms don’t allow trade copiers. Rules can differ by firm and account type and change over time, so check your firm’s current official rules before copying between accounts.

What we couldn’t assess

This review doesn’t test Replikanto, so it can’t confirm:

• how quickly trades are copied on one computer, a local network or the internet;
• how reliably FlowBots’ internet relay delivers trades;
• how often followers end up out of sync or need Follower Guard to act;
• how ATM Copy and the Rithmic re-read behave in fast markets;
• how responsive FlowBots’ support is.

Who Replikanto is best for

• NinjaTrader 8 traders copying their own trades between accounts in one NinjaTrader, or between their own computers on a local network.
• Traders who manage exits with ATM strategies and want followers to run the same ones.
• Traders who prefer a one-time licence and accept keeping NinjaTrader running on every computer involved.

Who should look elsewhere

• Traders who want copying to run in the cloud without their own computer: Tradesyncer is built that way.
• Traders automating TradingView alerts rather than copying a lead account: TradersPost and PickMyTrade are built for signal automation.
• Leaders copying over the internet to other people’s computers who need to see those followers’ positions directly.
• Mac users who don’t want to run Windows in a virtual machine.
• Prop-firm traders who haven’t confirmed their firm allows trade copiers.
