Mirror accounts as evidence in a dispute
A fill looks wrong. The broker says it was fine. With no independent record, the argument goes nowhere.
An old trick among experienced traders is running a second, smaller account at a different broker, or capturing a separate feed, to document what the market was doing at the same moment. If the feed shows 1.1042 and the fill on the first account was 1.1051, the gap is documented.
The evidence is only as good as the timestamps. Synchronized clocks and logs from both platforms, plus screenshots with visible time, make a stronger case than a verbal complaint.
It also keeps the conversation with the broker civil. Instead of "the fill was manipulated", the message becomes "the feed from provider X showed this price at this millisecond, and the fill was this far from it".
Most disputes are never settled in the client's favor, but a well-documented one at least gets a real answer.
Which kind of evidence has actually moved a broker to change an answer?
