Also known as: Collusion, Coordinated Trading, Bonus Arbitrage
Related party trading is coordinated trading between connected accounts — family, business partners, or the same operator behind several profiles — arranged to harvest volume-based rebates or bonuses rather than to take a genuine market view. The trades are structured so the group profits from the broker's incentives, not from price movement.
The classic mechanic is hedging across accounts. Two connected accounts take equal and opposite positions on the same instrument at the same time: one goes long, one goes short. Whatever the market does, one account wins roughly what the other loses, so the pair carries almost no net market risk. What they do generate is trading volume, and volume drives IB rebates, cashback, and bonus turnover requirements. The "profit" is the rebate skimmed off risk-free churn.
Brokers treat this as systemic abuse because the money comes straight from their marketing and rebate budgets. Risk teams look for mirrored trade timing, opposing positions of matching size across linked accounts, shared devices or payment sources, and volume that spikes without directional conviction. As an example, if two traders under the same IB simultaneously open 50 lots long and 50 lots short on EUR/USD and close together minutes later, they may net a small loss on spread but generate a $700 rebate for the IB — a direct transfer from the broker.
Because an IB is usually the one collecting the volume rebate, related party trading sits at the center of partner-fraud enforcement. Detection typically voids the tainted volume, reverses the rebates, and can terminate the IB agreement, since the pattern is treated as deliberate exploitation rather than ordinary trading.
The scheme relies on netting risk to near zero while maximising billable volume. Connected accounts open matched, opposing positions so the group's market exposure roughly cancels out, then close together. Each round trip adds to the volume the broker uses to calculate IB rebates or bonus turnover, even though the group barely moved its net equity.
Broker risk systems reconstruct these relationships from trade blotters and account metadata. They flag opposing trades of similar size opened within a tight time window, repeated mirror patterns between the same accounts, and links through shared IPs, devices, or funding cards. When the pattern is confirmed, the broker classifies it as collusion under the abuse clause of its terms, strips the tainted volume from rebate calculations, and reverses the payments already made on it.
Connected parties — or one operator's profiles — sit under the same IB and coordinate off-platform.
One account goes long and another goes short on the same instrument, in matching size, at the same time.
The paired positions cancel, so the group carries little net exposure while generating volume.
The volume triggers IB rebates, cashback, or bonus turnover credit — the actual objective.
Both legs are closed together, often within minutes, leaving only spread cost against the rebate.
The broker flags the mirror pattern, voids the tainted volume, and reverses the rebates paid on it.
Why it matters for partnership: Hedged trades across connected accounts manufacture rebate volume with no real risk — brokers void the volume, reverse the rebates, and can terminate the IB. Earn on genuine trading activity, not collusive churn.
Two traders under one IB on an ECN broker open 50 lots long and 50 lots short on EUR/USD within the same second and close minutes later. The pair loses only the spread but generates roughly 100 lots of billable volume, paying the IB about $700 in rebates. The broker's surveillance flags the mirrored timing and matched size, voids the volume, and reverses the rebate.
| Attribute | Genuine trading | Related party trading |
|---|---|---|
| Net market risk | Real, directional | Near zero (hedged) |
| Account relationship | Independent | Connected / coordinated |
| Profit source | Market movement | Broker rebate / bonus |
| Broker outcome | Rebates paid | Volume voided, rebates reversed |
Keep referred traders acting independently and never orchestrate group trades, because synchronized opposing positions of matching size are the clearest signature broker surveillance looks for.
Running a 'copy trading' or signal service that mirrors trades across related accounts purely to farm volume rebates, which brokers classify as collusion and unwind entirely.
Hedging within a single account can be legitimate, but coordinating opposing trades across connected accounts to farm rebates is treated as collusion. Intent and the account relationship are what brokers judge.
They correlate trade timing, position sizes, and instruments across accounts, then link the accounts through shared devices, IPs, or funding. A consistent mirror pattern is strong evidence.
It can, if the copied accounts are connected and the arrangement exists mainly to generate rebate volume rather than to follow a genuine strategy. Legitimate, disclosed copy trading between independent users is different.
The tainted volume is removed from rebate calculations and any rebates already paid are reversed. Bonus-linked gains from the scheme are typically voided under the broker's abuse clause.
No. Arbitrage exploits a pricing or feed error against the broker's book, while related party trading manufactures billable volume through hedged, coordinated positions to capture rebates or bonuses.
Yes. Because you collect the rebate, brokers treat facilitation as part of the abuse, so confirmed collusion in your referred flow can reverse your earnings and end the IB agreement.
