TradeSyncer Alternative: Different Position Sizes and Latency

Two mechanical questions bring people here: can each account carry a different size, and how long does a copy take? Both answered with the arithmetic and the measured samples.

People comparing TradeSyncer with something else usually arrive with two mechanical questions rather than a feature list: can I run different position sizes on different accounts, and how long does a copy actually take. This page answers both for Trepeat first, with the arithmetic and the measured samples, and gets to the rest afterwards.

One scope check, because it decides whether the rest is relevant: Trepeat connects demo accounts only, on MetaTrader and cTrader alike, and refuses a live real-capital account at connection. That is a deliberate constraint, not a gap waiting on a roadmap. Evaluation and funded accounts are supported on either platform — MetaTrader demo servers, or a cTrader demo account where the firm issues one — subject to the programme's own rules.

Trepeat has no affiliation with TradeSyncer. This page makes no claim about its pricing, its sizing behaviour, its latency or which accounts it accepts — read their own documentation for those, and check Trepeat's Plans against it yourself.

Different position sizes, in detail

This is the question the search data says people actually want answered, so here is the whole of it. Sizing on Trepeat belongs to the repeater — the link between one source account and one follower account — not to the account and not to a global setting. Two followers hanging off the same source can therefore be sized completely differently, and changing one does not touch the other.

• Fixed multiplier — the follower takes the source lot times a number you set. 0.5 halves it, 2 doubles it. Predictable, and the right choice when you have deliberately decided the proportion between two accounts.
• Equity ratio — the follower lot scales with the ratio between the two account equities. A follower a third the size of the source takes roughly a third the position, and it keeps tracking as either balance moves, so you are not editing a multiplier every time an account grows or draws down.
• Max Volume — a per-order ceiling applied after the sizing rule. Whatever the arithmetic produces, nothing larger than this reaches the follower broker. Useful when one account has a hard size limit the others do not.
• Rounding mode — Floor, Round or Ceiling, snapped to the follower symbol's own volume step rather than to a fixed assumption. Floor is the default, so the follower never lands above the size the rule intended. Brokers reject volumes that sit off their step, which makes this the difference between a copy that fills and one that is refused.

There is a calculator on the site if you want to see what a given source lot becomes before you set anything up, and position sizing when copying trades works through which rule suits which setup.

Sizing only helps if the order reaches the right instrument, which is why each repeater also carries its own symbol allowlist and symbol remapping. Brokers spell the same market differently — suffixes, spaces, a hash, or an entirely separate name for gold — and an order against a name the follower broker does not recognise simply does not land. Symbol mapping across brokers covers the patterns to expect.

Latency: where the time actually goes

The gap between a source fill and the matching follower fill is three separate things, and only the middle one belongs to any copier: how quickly the source broker reports the fill; the engine's own work of sizing, checking and dispatching; and the follower broker's execution, which is usually the largest and by far the most variable of the three.

That third leg is why a headline millisecond figure is worth less than it looks. It belongs to a different company, it moves with the instrument and the session, and no copier — cloud or local — can shorten it. Trade copier latency takes that argument apart properly, and why follower fills differ explains why a different price is usually spread rather than lag.

For order of magnitude only, and nothing more: on a development environment on 28 September 2026, single samples measured about 417 ms from a MetaTrader source to a cTrader follower, 702 ms from MetaTrader to MetaTrader — those two from the same source fill in the same repeater — and 265 ms from cTrader to cTrader. Each figure runs from the moment the fill reached the engine to the moment the follower broker confirmed, so the source-broker leg is not in it.

These are one-off observations, not a benchmark and not a commitment. Read them as “a fraction of a second” and no further. What your own accounts do depends on the two brokers involved, the instrument and the state of the market at that moment. Each repeater also sets its own limit on how long a confirmation may take before the copy is treated as failed, and a failed copy raises an alert naming what the broker reported rather than leaving you to find the gap at the end of the week.

Three platforms, copied in any direction

Trepeat connects MetaTrader 4, MetaTrader 5 and cTrader and repeats across them in either direction — a cTrader source driving MetaTrader followers, or the reverse, or any mix. On cTrader you sign in with your cTrader ID, so a password is never shared. If your accounts live on a platform outside those three, Trepeat cannot connect them and you should check what any alternative lists before subscribing to either.

Further platforms are planned with no date attached, so judge Trepeat on what it connects today. And whichever platform your firm issues on, the account has to be a demo one — a challenge placed on a live account cannot be connected, on MetaTrader or on cTrader. Copying between MetaTrader and cTrader covers what crosses the boundary and what does not.

What the rest of the Plan carries

• Your manual positions are off limits to the engine — every order Trepeat places carries its own stamp, and it will only ever close one of its own. You can trade a follower account by hand while it sits in a repeater. On a netting account the broker merges same-symbol positions, so a copy can join one you already hold — Trepeat then refuses to close it and says so, rather than closing your trade with it.
• One unhealthy follower does not stop the others — it is set aside on its own and rejoins when its connection recovers, while the rest of the repeater carries on.
• Live P&L per account and per repeater — open positions valued as prices move, on one dashboard, rather than assembled from closed trades afterwards.
• Close origins recorded — a repeated close, a close made by hand in the broker terminal and a close through the Flatten button are three different entries in the history.
• Nothing to install — no VPS, no Expert Advisor, no always-on PC; you Run and Stop a repeater from the web app, and repeating continues whether your machines are on or off. See cloud vs local trade copiers.
• Journal, alerts and full trade history included — one flat monthly Plan from $29, no share of anything, and no money moves through Trepeat: every account stays with its own broker in your name.

What a comparison page cannot settle

Whether you may run a copy tool on a given account is set by that account's own paperwork — your broker's terms, or the rulebook of a proprietary trading firm's evaluation or funded programme. Trepeat does not read, enforce or interpret those rules, and neither does any alternative. Rules on copy trading covers the clauses worth finding before you connect anything. Nothing here is legal advice.

Confirm, too, that every account you intend to connect to Trepeat is on a supported demo server. An account described as funded still needs that check — the label alone does not establish the server type.

Which belongs on your shortlist

• You need live real-capital accounts — not Trepeat. Cleanest test on the page, and worth applying before you read any further.
• You need a platform outside MetaTrader and cTrader — check what the alternative lists and confirm your exact pairing in its documentation.
• You want each account carrying a different size — that is a per-repeater decision here: multiplier or equity ratio, a Max Volume ceiling, and a rounding mode snapped to the follower symbol's own step.
• You care what happens when a copy does not land — an alert naming the broker's reason, a per-repeater confirmation limit, and a history that records which side closed what.

If the last two describe you, the deciding question is not whose published millisecond figure is smaller — neither of them includes your follower broker, which is the leg that usually dominates — but which tool gives you the sizing controls your accounts actually need and tells you plainly when something did not go through. There is a 7-day trial, and connecting one source and one follower for a session settles it faster than any comparison page can.
