Properties

OptionalallowFractionalQty

allowFractionalQty?: boolean

Set true only for a venue that genuinely trades fractions, such as crypto. Absent means whole quantities, which is every Indian equity and F&O contract and the reason fractional quantities are rejected by default: a fractional quantity reaching those brokers is a defect, not a preference. A lotSize grid still applies when this is true.

OptionalfreezeQty

freezeQty?: number

Max quantity per single order (exchange freeze limit).

OptionallotSize

lotSize?: number

Contract lot size. When set, quantity must be a whole multiple of it: 100 on a 75-lot future is rejected here rather than by the exchange.

OptionalpriceBand

priceBand?: PriceBand

tickSize

tickSize: number
