What is a rule set version?

Versions give your rules a history.

What a version contains

• The core limits: daily drawdown, maximum drawdown and profit target percentages, minimum trading days and allowed instruments.
• The full list of rules from the builder, each with its parameters and action.
• A version number and effective date.

How versions relate to accounts

• An account type points at a rule set.
• When an account is created, it takes the rule set's current version.
• That version stays attached to the account forever.

Why immutable

If a version could be edited, an account's rules could change without anyone noticing. Making versions append-only means the record of what a trader agreed to is permanent.

Using versions in practice

• Rules pages: date each published version.
• Support: answer "which rules apply to me?" from the account's version.
• Analysis: compare pass rates between versions to see whether a rule change worked.

Absent rules

A version can leave out a rule entirely, for example no profit target for an instant funding account. An absent rule is recorded as absent, never as zero.
