- Stock splits require price history and position adjustments.
- Dividends are usually applied as cash adjustments to open positions.
- Futures-based CFDs need scheduled rollovers.
Stock splits
When a share splits, the price changes overnight. Open positions and, where supported, price history must be adjusted so clients are not unfairly affected.
Dividends
For stock and index CFDs, dividend adjustments are applied to open positions on the ex-dividend date: long positions are usually credited and short positions debited, according to your policy.
Rollovers
CFDs based on futures must move to the next contract before expiry. Plan the schedule, announce it and apply any price-difference adjustments consistently.
Keep a calendar
Maintain a monthly calendar of corporate actions and rollovers for all offered instruments, and review it weekly.
