We currently offer two types of options on the Zentrader platform, Classic and On Demand. The differences are as follows:
Classic
Classic options run on a fixed time schedule (15 min, 30min, 1 hour and 1 day). Traders may enter and exit the option at any time up until the no-trading point just before expiry.
On-Demand
The countdown of the selected timeframe (30 sec, 60 sec, 3 min or 5 min) begins when the trade is entered into.
