What is FX Blue good at?

Turning an account into numbers, at no cost. free account-analysis and verified-stats tools; no paid tier published — which for a forex trader who wants drawdown, session and pair-level breakdowns is a lot of value for nothing.^[1]

kappi's public profiles report a narrower set on purpose: Public profiles carry PnL, RME, correlation to SPX, mean R:R and trade count over 30/100/200-day windows.

Where does analysis stop and attestation begin?

Analysis is a function of data you already have — feed it in, get a truer description of it out. Attestation is a statement to a third party that something was the case at a time, made in a way they can check without trusting either of you.

The distinction sounds academic until someone doubts you. Nobody disputes a Sortino ratio; they dispute whether the account is yours, whether these are all the accounts, and whether the plan you say you followed was written before or after the trades. No amount of analytical depth touches any of the three, because all three are questions about provenance rather than performance.

Every sealed commit is hashed into a Merkle tree and anchored to Hedera, so the log is append-only and independently checkable.

Why forex makes this sharper

Forex has the most developed verification culture of any market — read-only investor passwords, published stats pages, widget badges — and it still has a signal-seller problem, because every one of those tools verifies the account rather than the claim. A trader can run a verified account and separately post calls that bear no relation to it, and both artifacts are honest on their own terms.

Broker-import journals prove what you did after the fact, from data you control. kappi timestamps what you said you would do, before you knew how it would turn out, on a record you cannot edit.

Can you use both?

Yes, and for a forex trader that is the sensible configuration: FX Blue for free analysis of what the account did, kappi for the record of what you said you would do. They do not overlap, and the combined cost is $15 a month.

When should you pick FX Blue?

When you want deep analysis of a live account and nobody is asking you to prove authorship of anything. It is free, it is mature, and for a trader working on their own performance the analytics are the useful half.

When should you pick kappi?

When the record has to persuade someone. $15 a month, $12.75 through a referral link, and no free tier. kappi is broker-agnostic. Commits are made from the Chrome extension, so any brokerage works — or your own journal, kept wherever you already keep it. No import, no account linking, no requirement to trade inside someone else's platform.
