Why Every Copied Trade Needs an Audit Trail

Why a trade copier needs a real audit trail: reconstructing a trading day for a payout review, catching a misconfigured ratio early, and proving what actually copied and when.

A copier that doesn't log what it did is asking you to trust it blind. Multiply that across several accounts trading automatically off one leader, and "trust it blind" stops being a reasonable ask - you need an actual record of what copied, to which account, and at what price.

The obvious reason: a payout review can ask for detail

Some prop firm payout reviews come with specific questions - what happened on a given day, on a given account, sometimes down to individual trades. If your accounts were trading automatically off a leader, reconstructing that from memory or broker statements alone is slow and error-prone. A copier's own log, showing exactly what it copied and when, answers the question directly instead of making you guess.

The less obvious reason: catching a bad ratio early

An audit trail isn't just for after the fact. Reviewing what actually copied to each follower - at what size, relative to what the leader did - is how you catch a misconfigured ratio before it's cost real money across a dozen trades instead of one. The log is a diagnostic tool for today's setup, not just a record for a future question.

What a real audit trail actually needs to show

A useful log records, at minimum, which leader trade triggered a copy, which follower account received it, the size it copied at, and the timestamp - for every single trade, not a summary. Anything less makes it hard to answer a specific question about a specific day, which is exactly the situation an audit trail exists for.

This matters more as you add accounts, not less

A single leader-to-follower pair is easy to keep track of mentally. Add a third account, a fourth, different ratios and different limits on each, and manual tracking stops being realistic. The value of a real audit trail scales with how many accounts are actually connected - it's most useful exactly when you'd be least able to reconstruct events without it.

Every copied trade, logged automatically

Qloner logs every copied trade in the Event Log - what copied, to which account, at what size, and when - without any manual tracking on your part. If a payout review or a ratio question ever comes up, the record already exists.

  • Which follower account received it
  • The size it copied at
  • The exact timestamp
  • Every single trade - not a summary
