Instruction PDF or chat screenshot?

Prefer the formal instruction file or system export. If you only have chat, export a clean PDF and timestamp that—but expect higher challenge than a signed instruction form.

Client revises the instruction after the close?

Timestamp the revision as a new file. Keep the earlier timestamped instruction. Do not delete prior certificates.

Does a timestamp authenticate the client’s identity?

No. It dates the file bytes. Identity and authority still come from your onboarding and signing process.

What about audit over confirmation chronology?

Produce the confirmation exports you held at the time, each with a certificate. A timestamp supports sequence; it does not replace regulated books and records.

Before a trade instruction, confirmation or authorisation is acted on—or challenged later—timestamp the exact file you received or issued. TimeBinder^® makes a fingerprint in your browser. The files stay on your device. You get a checkable Proof of Time Certificate that shows each exact file existed no later than a recorded time. It does not show who authorised the trade, whether best execution occurred, or how a complaint must end. Free to start.

The routine: date instructions before they move

Freeze the set: client or desk instruction PDF/CSV, authorisation, order ticket export, trade confirmation, and any revision that replaces an earlier instruction.
Optional. Check hashes with the free SHA-256 hash checker.
Timestamp the pack (up to 10 files or one zip). Your first Pooled TimeBind is free, with no credit card required.
Save the Proof of Time Certificate with the order or compliance file.
Execute or forward. If the client sends a revised instruction, timestamp the new file before you act on it. Do not overwrite the earlier dated copy.

See how to timestamp a file, prove source code existed before a date for the same hash habit on technical exports, and OTS as evidence.

Situations this habit is built for

Useful points from the retired trade-instruction Scenario pages:

Backdating risk. Once a file’s fingerprint is anchored, a later rewrite has a different hash. That does not prove who typed the instruction; it shows the later bytes are not the earlier ones.
Partner and client disputes over “which instruction.” Seven-figure tickets often turn on whether the firm used the original or a superseded PDF. Keep both, each with its own timestamp.
Trade confirmation timing. Allocations and confirms disputed after the fact need a dated confirmation export, not only OMS screen prints.
Missing authorisations. Audits escalate when trade authorisations cannot be produced with a credible chronology. Timestamp authorisations when granted and store the certificate with the mandate file.
Fund allocation and derivatives chronology. Allocation sheets and derivatives compliance reports that change after a market move should be new dated versions, not silent edits.
Arbitration and high-value portfolio fights. Independent time evidence supports chronology; it does not decide fault or quantum.
Related illustrative scenarios. See trading instructions proven authentic after a timing dispute, a trading authorisation dispute resolved with a timestamp, trading records proved authentic under regulatory scrutiny, and a trading authority dispute resolved with a document timeline.

Why desk systems alone are often challenged

OMS and EMS clocks are internal. Exports can be regenerated. Email “sent” times do not hash attachments. A blockchain timestamp is independent of your firm’s servers. See how long a Bitcoin timestamp takes.

What a TimeBind shows, and what it doesn’t

A TimeBind shows that this exact file existed no later than the recorded time. It does not show authorship, trading authority, best execution, market abuse findings or ownership of assets. It does not replace compliance policies, recording rules or legal advice. This is general information, not legal advice.

Your file’s fingerprint, anchored to a global network secured by real electricity and cryptography.

Editing a file—including with AI—changes its fingerprint, not its existing network record.

How this works

Your file’s SHA-256 fingerprint, a short code worked out from its exact contents, is made in your browser, and the file itself stays on your device. A cryptographic commitment to that fingerprint, which may be combined with others, is then anchored in a block on the Bitcoin blockchain. Bitcoin is secured by proof of work: computers around the world spend real electricity to add each block, and changing an earlier block would mean redoing that work faster than the rest of the network. Until that block is confirmed, your proof is pending. Once the Bitcoin anchoring is confirmed, you can verify the proof against that recorded commitment. The confirmed record can then be checked; Pooled TimeBinds are checked through TimeBinder, while ASAP TimeBinds can also be checked independently. If you check the file later and its fingerprint still matches, that shows the file existed no later than the recorded time. The record doesn’t show who made the file, whether AI was used, or that its contents are true.
