ChartStreak Official Tournament Rules

Last updated: 16 October 2026

These rules govern the ChartStreak weekly tournament. They sit alongside the Terms of Service, which apply to everything else, and the Privacy Policy, which covers your data. Where these rules and the Terms disagree about the tournament, these rules win.

1. Sponsor

The tournament is run by Pavel Kastsiukou, Cyprus. Postal address: Andrea Zakou 11, 102, Mesa Geitonia 4000, Cyprus. Contact: [email protected].

Apple, Google and Telegram do not sponsor, endorse or administer this tournament, and are not parties to it. It is run entirely by the sponsor named above.

2. No purchase necessary

Entry is free, and a purchase neither helps you nor is required. A premium subscription grants no place, no prize and no scoring advantage — it unlocks practice tools that play no part in how a competitive day is scored. Everything that decides a result is available to every account.

3. Who can enter

• You must be 18 or older.
• You may enter from any country or territory, except those covered by the next point.
• You must not be a person or in a territory subject to sanctions that would make it unlawful for us to award you a prize.
• You must hold one account with an e-mail address linked to it, and it must be yours. A Telegram account on its own is not enough: the daily challenge is the only way into the standings, and it cannot be played without a linked e-mail address.
• The sponsor, and anyone who worked on ChartStreak, may not win a prize.

4. The period

A tournament period is one ISO week in UTC: it opens on Monday at 00:00 UTC and closes at the end of Sunday. Weeks are identified as YYYY-Www, and the year of a week is decided by its Thursday — so a week that straddles New Year belongs to one year only, and there is never more than one set of prizes for it.

5. How to enter, and when a day counts

Play the daily challenge. A day is added to your week when:

• you answered at least 3 of that day's 5 charts — a day of abandoned charts is not an entry; and
• the day was started by an account that was already secured — in practice by an e-mail address, since without one the day cannot be played at all. Securing an account halfway through a day does not bring the earlier part of it into the standings.

A day you did not play is not a zero — it is absent. Joining on Wednesday does not put two zeros behind you.

6. Scoring

• Each chart scores 0 to 100 points by how close your forecast is to the closing price, measured against how far the price actually moved: 100 for the exact price, 50 for a miss as large as the whole move — the same as forecasting no change — and 25 for a miss one and a half times that size. Beyond that the score keeps shrinking: the whole move in the wrong direction scores about 14, three times the move about 6, and only a forecast wildly off — more than 106 times the move away — rounds down to 0. When the price barely moves, the miss is measured against half the chart's typical move instead.
• A day is the sum of its 5 charts. A chart left unanswered when time runs out scores 0.
• Your week is the sum of your best 5 of the 7 days. One bad day does not end a week.
• Our servers are the sole scorer. Your device draws the chart and counts down for you; the answer that counts is the one our servers recorded, within the time our servers measured. That record is final.
• A tie shares the place. Two players on the same total both take the higher rank, and the next rank is skipped — places run 1, 2, 2, 4.

7. The prizes

• Every week the top five places win days of ChartStreak Premium. The number of days for each place is fixed and shown on the tournament screen (section 8); it does not depend on how many people play or on the subscription price.
• A week with fewer than 10 qualifying participants is not played out. No prizes are awarded for it. Handing prizes to three people is a hand-out, not a tournament.
• A partner may fund an additional partner prize for a week. It is announced for that week, set in money and divided as described in section 8. Once announced, it can be raised, never lowered: you played for what you were shown. A partner prize never changes the premium days of a place.

8. What each place wins

Places one to five win 7 / 4 / 3 / 2 / 1 days of ChartStreak Premium. Players sharing a place each win that place's full prize, and the next place is skipped: two players sharing first place win 7 days each, and the next player, in third place, wins 3.

A partner prize is divided among the same five places in the same proportion, 7 : 4 : 3 : 2 : 1, by the largest-remainder method, so not a cent of it goes missing. Money, unlike days, cannot be given twice, so players sharing a place share the combined amounts of the places they occupy. Any amount not awarded is recorded as carried out.

9. How a prize is paid

A prize is paid in days of ChartStreak Premium added to the account that won it. There is no cash option: nothing is transferred to a bank, a card or a cryptocurrency address, and we never ask you for an address or for documents.

The days for a place are credited automatically when the week closes. There is nothing to claim, and they do not expire. We let you know by e-mail.

A partner prize is claimed on the prizes screen. It converts at the ordinary subscription price, with no markup and no discount, and is rounded to the nearest whole day. The prize converts in full — nothing is left over and nothing is held back. A prize too small to reach half a day still pays one day rather than nothing.

Premium days are added to the winning account and cannot be transferred, sold or exchanged for money. If that account already has Premium, the days extend it.

You have 30 days from the end of the week to claim a partner prize — and never fewer than 7 days from the moment the prize was awarded. An unclaimed partner prize expires at the end of that window and is not paid. We send a reminder 7 days before it does.

10. Prizes are shown in premium days

The prize of a place is a fixed number of days, and that is the number the tournament screen shows. A partner prize is set in money and converts into days at the subscription price in force when it is claimed (section 9), so a change of price before you claim changes the number of days with it.

11. Taxes

Any tax on a prize is yours to declare and pay. We do not withhold, and we cannot advise you on it.

12. Disqualification

Automation, more than one account, coordinating accounts, or interfering with a round disqualifies the account from the period — see section 6 of the Terms of Service for what each of those means. A disqualified award is withdrawn by a recorded entry, not by erasing what happened, and you will be told that a decision was made. Write to [email protected] to dispute one.

An account suspended for review before a week's places are fixed at closing is left out of that week's table, and the places below it move up. An account suspended after the places are fixed but before the days are credited keeps its place but does not receive that week's premium days, and they do not pass to the next place. Days already credited to an account later disqualified are withdrawn; if paid Premium was added on top of them, the withdrawal shortens it by the same number of days. We may also hold a partner prize while a check is running. A hold is not an accusation; it ends in a payment or in an explanation.

13. Changes to these rules

The prizes, the schedule and these rules may be revised. A revision is announced at least 30 days in advance, and never worsens a period that has already started — the rules you played under are the rules you are judged by. Each published version carries the date it took effect.

14. Law

These rules are governed by the laws of the Republic of Cyprus. Where local law prohibits a tournament of this kind, or makes any part of these rules unlawful, entry from that territory is not permitted rather than the rule being waived.
