instrument opening price
Establishing annual, quarterly, daily and hourly openings would be interesting as a point of openings, position closings, sending alerts, taking part of profit, etc.
Open prices are inflection points, many times, where the market pauses or starts a reversal.

It will open a new deal on every new bar (if previous deal is closed).
Why do you need to open one deal per quarter/year?!?! Can't imagine such strategy.
