One Piece TCG · Market intelligence
Know when to buy, hold, or sell. And see the proof.
We track every One Piece card, box, and tin daily and stamp each with a plain-English verdict. Our buy calls finished higher 8 weeks later three times out of four, in a market where most cards fell. Don't take our word for it: every call is logged publicly the day it fires and graded automatically. We can't edit it, and you can check it right now.
1,004 verdicts fired on today's board. Free Google sign-in, takes 10 seconds. No card, no trial clock. The track record is public either way.
A buy list that shows its work
Our rules were built the way you'd want them built: tested against years of real recorded prices before a single call went live, held to the same standard in every era, and re-tested against the growing dataset every month. What exactly goes into them stays in the vault. What comes out of them is published below, and the market's own performance is the benchmark we hold ourselves against. Every row is a flavour of our ACCUMULATE stamp: the same buy signal, ranked by how much conviction the pattern earned in testing.
| Buy tier | Higher 8 weeks later | Median return | Up, never dropped 5% along the way |
|---|---|---|---|
| High Conviction | 84% | +22.1% | 81% |
| Riding the High | 84% | +16.8% | 83% |
| Premium Climb | 75% | +11.2% | 73% |
| Momentum | 65% | +14.8% | 59% |
| The market overall (every card, no selection) | 45% | −3.2% | n/a |
Backtested against 2.5 years of real recorded prices, with every flag counted: winners and losers. The typical High Conviction call never traded below its flag price at all. Past results never guarantee the future, which is why the live ledger grades every new call in public. Watch the record hold, or watch it break. Either way you'll see it. These are observations from the data, not financial advice; the ledger exists so you can judge how good the observations are.
Every card gets a stamp. Every stamp gets a reason.
No jargon and no black box. Open any card and read exactly why it carries the verdict it does, in plain English.
An established climb still in motion, qualified against the version of the pattern our testing says actually pays: premium strength, or cheaper cards with room to run below their peak.
Falling hard, or a big run rolling over. Historically these kept falling more often than not. If selling was on your mind, this is the flag.
eBay listings drying up while the trend holds and the price hasn't spiked yet. Rare, and the classic setup before a move.
Washed out and just turning upward with the panic cooling. Speculative by design: small positions, eyes open.
Everything else gets HOLD: no signal worth acting on, and we say so rather than inventing one.
