Rollover & basis
How do algorithmic futures systems manage data alignment during the three transition days of quarterly contract rollover?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Operators of algorithmic trading systems must handle continuous-chart data mapping, open-position carryover, and volume-based roll thresholds across the contract roll window to avoid false signals from mismatched contract-month data.
How it works
This is a vendor- and firm-specific engineering practice rather than an exchange-mandated procedure: automated systems commonly pause new signal generation or apply manual overrides during the multi-day roll transition since indicator values (moving averages, volume profiles) can be distorted by contract-switching artifacts described in exchange historical-data documentation.
An example
A bot suspends new entries during the roll window to avoid acting on a distorted indicator value.
Risk & limitations
There is no single exchange-mandated roll-handling standard; poorly configured systems can still misfire trades during rollovers.
