EqMarginCall¶

Calls¶

try_margincall_external¶

Tries to margin-call an account from another account signed call.

Attributes¶

Name	Type
who	`<T as system::Config>::AccountId`

Python¶

call = substrate.compose_call(
    'EqMarginCall', 'try_margincall_external', {'who': 'AccountId'}
)

Events¶

MaintenanceMarginCall¶

Event is fired when an account achieves the maintenance_margin level. [main_acc, maybe(subacc_type,subacc_id), timer]

Attributes¶

Name	Type	Composition
None	`T::AccountId`	`AccountId`
None	`Option<(SubAccType, T::AccountId)>`	`(None, (('Bailsman', 'Trader', 'Borrower'), 'AccountId'))`
None	`u64`	`u64`

MarginCallExecuted¶

Event is fired when an account is liquidated. [main_acc, maybe(subacc_type,subacc_id)]

Attributes¶

Name	Type	Composition
None	`T::AccountId`	`AccountId`
None	`Option<(SubAccType, T::AccountId)>`	`(None, (('Bailsman', 'Trader', 'Borrower'), 'AccountId'))`

Storage functions¶

MaintenanceTimers¶

Python¶

result = substrate.query(
    'EqMarginCall', 'MaintenanceTimers', ['AccountId']
)

Return value¶

(None, 'u64')

Constants¶

CriticalMargin¶

critical_margin setting, when the margin is below this value, a position is liquidated immediately

Value¶

50000000

Python¶

constant = substrate.get_constant('EqMarginCall', 'CriticalMargin')

InitialMargin¶

initial_margin setting, when the margin is below this value, borrowing is prohibited

Value¶

200000000

Python¶

constant = substrate.get_constant('EqMarginCall', 'InitialMargin')

MaintenanceMargin¶

maintenance_margin setting, when the margin is below this value, a MaintenanceMarginCall event is fired

Value¶

100000000

Python¶

constant = substrate.get_constant('EqMarginCall', 'MaintenanceMargin')

MaintenancePeriod¶

maintenance_period setting, a time period (in seconds) when the margin account can be topped up to the initial_margin setting to avoid a margin call

Value¶

Python¶

constant = substrate.get_constant('EqMarginCall', 'MaintenancePeriod')

Errors¶

ZeroCollateral¶

Not allowed with zero collateral
