Replikanto: information and detailed review

Replikanto is a trade copier that runs inside NinjaTrader 8. You trade on one account, the leader, and it copies every order to your other accounts, the followers, as long as they are connected to NinjaTrader: Rithmic, Tradovate, Interactive Brokers or any other broker NinjaTrader supports. It is not a cloud service or a subscription: it is software you buy once and run on your own computer.

We read its website, its entire help center (232 articles), its license terms, the 115 Trustpilot reviews of its company, FlowBots, that you can read without an account, around thirty Reddit threads and the copy trading rules of the futures prop firms we track.

Who is behind it

It is sold by FlowBots, active since 2017, which describes itself as a team of traders and developers building NinjaTrader add-ons. Its website does not give the company's legal name or where it is registered. Its support works on New York hours, and Replikanto comes in English and Portuguese.

What to know from its terms before paying:

• You have 14 days to get a full refund, no questions asked. That is more generous than most copiers. There is only one refund per product and person, and support renewals are not refundable.
• It is not liable for any damage, direct or indirect, caused by the software.
• It requires you to monitor your accounts while trades are open.
• It sends error reports identified by your computer's ID, without account numbers or orders, according to its terms.

What "lifetime" means

It is the most repeated complaint in its reviews, so it comes first. The "Lifetime" license never expires: the software keeps working forever with the version you have. But updates and support are only included for the first year. After that they cost $39 a year. Its help center says that, as a courtesy, new versions remain downloadable, but this is not guaranteed.

Several users say they feel misled by the word "lifetime". The company replies that it is explained on the purchase page and in the terms. Both are true: it is explained, but you have to read it.

How it works

You open a Replikanto tab in NinjaTrader, choose the leader account and the contract, and switch the followers on. Each tab copies one leader account on one contract; for another contract, you open another tab.

• Windows only. NinjaTrader 8 only runs on Windows; on a Mac you need a virtual machine, and they do not support that. There is no mobile or web version.
• NinjaTrader must stay open. If it closes or loses the broker connection, copying stops.
• Where you trade from. NinjaTrader charts and SuperDOM, ATM and automated strategies, and also the Tradovate web or mobile apps and TradingView, if the leader is a Tradovate account.
• Several brokers at once. To mix, say, Rithmic and Tradovate, you enable NinjaTrader's free multi-provider option.
• Several computers. It can copy to another computer on your network or a remote one, such as a VPS. Each computer needs its own license, and copying over the internet uses credits.

Which accounts it works with

The rule is simple and its help center repeats it: if the account can connect to NinjaTrader, Replikanto can use it. Rithmic, Tradovate, Interactive Brokers, CQG and other NinjaTrader brokers, plus simulation and market replay accounts.

What it cannot use: ProjectX and TopStepX as separate platforms, Match-Trader, MetaTrader, Quantower or ATAS on their own. It works with futures and stocks, not MetaTrader forex.

How it sizes trades

It has seven methods, more than any other copier we have analysed:

• Exact quantity: every follower copies the same number of contracts.
• Pooled quantity: splits the leader's order between followers.
• Ratio: each follower multiplies by its own number, from -100 to 100.
• Pre allocation: each follower always gets the contracts you assign.
• By account value, by available cash or as a percentage of the position: designed for stocks.

Watch out for two details:

• It rounds down. With a 0.5 ratio, a 1-contract order on the leader becomes 0 on the follower and is not copied.
• A negative ratio copies in reverse. The follower goes against the leader. Its own help center warns this is hedging across accounts, which most prop firms forbid.

On top of that, Cross Order copies between sizes of the same contract, for example ES on the leader and MES on the follower, across 36 futures families. And ATM Copy makes each follower manage its exit with your NinjaTrader ATM strategy, instead of copying exits one by one.

Which orders it copies

It copies market, limit, stop, stop limit and MIT orders, OCO brackets, stop and target moves and cancellations. With Market Only, it only copies what fills, at market: fewer errors and fewer Tradovate calls, in exchange for a different entry price.

Speed, according to its help center:

• On the same computer: 10 to 200 milliseconds.
• On your local network: 50 to 500.
• Over the internet: 100 to 1,000.

They recommend no more than 20 followers per leader: beyond that, delay and the risk of mismatches rise. And they warn that slippage shows with very fast scalping.

The protections

• Follower Guard. If a follower falls out of sync, goes opposite to the leader or has an order rejected by the broker, it can flatten it, disarm it and email you. Each protection is enabled separately.
• Rithmic check. Before flattening a follower, it asks Rithmic again for the real position, because NinjaTrader sometimes shows positions the broker has already closed.
• Settings lock during a trade, so a mid-trade change does not leave part of a position uncovered.
• A button to flatten everything on the leader and its followers, including on other computers.

What it does not have: daily loss or profit limits. Its help center refers you to setting them at the broker.

Stealth mode and compliance mode

Two features worth knowing about if you have prop firm accounts:

• Stealth Mode. Removes from copied orders the identifiers that show they come from Replikanto. The company presents it as an option for advanced users.
• Compliance Mode. A free version for customers, built according to FlowBots "in collaboration with prop firms". It removes four things: internet copying, local network copying, negative ratios and stealth mode. Its page explains why: firms see them as "fraud vectors".

According to its help center, only two firms are currently listed as having explicitly approved Compliance Mode: Take Profit Trader and Elite Trader Funding. If you use prop firm accounts, our recommendation is clear: use that version.

What prop firms say

Replikanto connecting to your account does not mean you are allowed to use it. This is what the official rules say at the futures firms we track:

Firm	Copy trading	What you need to know
Alpha Futures	Allowed	Only between your own accounts. They recommend the smallest account leads
Blue Guardian Futures	Allowed, including external copiers	Opposite positions across accounts are forbidden
E8 Futures	Allowed	Hedging across accounts is forbidden, even if they are all yours
FTMO Futures	Allowed between your accounts	Each account must follow its own rules
FundedNext Futures	Allowed, including with other firms	They may ask you to prove every account is yours
The5ers Futures	Limited	Only 25K and 50K accounts, up to $75,000 in total
Top One Futures	Allowed	Up to 10 or 20 accounts, depending on the plan
Earn2Trade	Forbidden	They can refuse accounts and withdrawals if you used a copier

Source: each firm's help center or official terms, checked on 8 October 2026. Rules change: check your firm's page before copying. And check that each account can connect to NinjaTrader.

The real risk is opposite positions. FlowBots' own help center explains how it happens: you close the leader, a follower does not close because of a dropout, you flip the leader, and the follower ends up holding a position in each direction. On Trustpilot and Reddit there are cases of prop firm accounts closed for this: five accounts in one case, and in another a 38-second hedge while switching from NQ to MNQ. The company replies that it can happen with or without a copier. Its advice, and ours: check that every account is flat before each entry.

What users say

FlowBots scores 4.7 out of 5 on Trustpilot, from 127 reviews. But 103 of the 115 we read arrived through an invitation link, almost all are from 2026 and most thank support for a specific query. Our review analysis above breaks it down.

What comes up most:

• Support gets involved, with days of follow-up until a problem is solved. But it is email only and during business hours, and some complain of only getting a link.
• The "lifetime" license is complaint number one.
• Serious but rare failures: a follower with triple the contracts, opposite positions when stops triggered, and 15 to 30 point differences on MNQ when trading from TradingView. The company blames duplicates on two connections to the same broker being open at once.
• Reddit is divided. Some have used it without issues for years, while others moved to Tradecopia, Tradesyncer or CrossTrade over speed or failures.

How to use it well

1. If you have prop firm accounts, install Compliance Mode.
2. One connection per broker account in NinjaTrader, and one Replikanto tab per contract. It is the number one cause of duplicate orders.
3. Turn on Follower Guard with flatten, disarm and email alert.
4. Check that every account is flat before each entry, and never flip a position in one go.
5. Use ratios of 1 or more, and never negative ones with prop firm accounts.
6. Turn on Market Only if you use Tradovate with many accounts or move your stop a lot.
7. Do not go beyond 20 followers per leader.
8. Set daily limits at the broker, because Replikanto does not have them.

Alternatives

• Tradecopia: can also run on your computer, connects Tradovate and Rithmic without NinjaTrader, and has daily risk limits. Subscription based.
• Tradesyncer: cloud based, with a journal included, no need to keep your computer on.
• Traders Connect: cloud based, and it also connects CFD accounts.
• Your platform's own copier. If all your accounts are on Tradovate, its Group Trade is free.

Verdict

Replikanto is the most complete copier we have analysed for NinjaTrader: seven sizing methods, ATM strategy copying, mini to micro mapping and serious protections against mismatches. Its documentation is among the best, and the one-time payment with a 14-day refund window works in its favour.

In exchange, it ties you to Windows and an open NinjaTrader, has no daily loss limits, its "lifetime" does not include updates after the first year, and it has a stealth mode prop firms themselves frown upon. Use it, but in its Compliance Mode version, and only at firms that allow copying.

Who it is for: futures traders already on NinjaTrader in Windows, with several Rithmic or Tradovate accounts, who want plenty of sizing options and prefer to pay once.

Who it is not for: anyone trading on a Mac or from their phone, anyone who wants daily loss limits inside the copier, and anyone who does not want NinjaTrader open all day.
