Responsible trading

STX is required by gaming regulations to provide tools that allow users to control and limit their own participation. These limits are also available via the API.

Account Limits

Each account has two sets of limits:

• Admin limits — set by STX. They define the ceiling a user cannot exceed.
• Account limits — set by the user. They can be equal to or lower than the admin limits, but never higher.

Users who want higher admin limits (e.g. market makers who require a higher order liability ceiling) must contact STX support. Default admin limits are calibrated for casual participants, not professional traders or market makers.

Available Limit Keys

Key	Description
DAILY_DEPOSIT	Maximum deposit per calendar day
WEEKLY_DEPOSIT	Maximum deposit per week
MONTHLY_DEPOSIT	Maximum deposit per month
LIFETIME_DEPOSIT	Maximum total deposits over the life of the account

MAX_ORDER_LIABILITY_PER_ORDER	Maximum liability on any single order

LOSS_LIMIT_MONTHLY	Maximum realised loss per month
HOURS_PER_DAY	Maximum hours of app usage per day (optional, for problem gambling support)

Querying Limits

query {
  accountLimitsNumber {
    accountLimits {
      orderLiability
      maxOrderLiabilityPerOrder
      dailyDeposit
      lossLimit24Hours
    }
    adminLimits {
      orderLiability
      maxOrderLiabilityPerOrder
    }
  }
}

Setting a Limit

mutation {
  setLimitNumber(key: ORDER_LIABILITY, value: 50000) {
    accountLimits {
      orderLiability
    }
  }
}

Setting value: null removes a user-set limit (the admin limit still applies).

The COOL_OFF_PERIOD limit requires the user’s current password as a safety check:

mutation {
  setLimitNumber(key: COOL_OFF_PERIOD, value: 24, password: "current-password") {
    accountLimits {
      coolOffPeriod
    }
  }
}

Self-Exclusion

Users can permanently close their account via the closeAccount mutation, or set an indefinite self-exclusion period using setLimitNumber with the appropriate responsible gaming limit keys. Contact STX support for guidance on the self-exclusion process.
