Margin and collateral requirements vary from instrument to instrument and can be changed at any time to reflect market conditions.
For CFDs and Options that have stocks as underlying instruments, the risk rating of the underlying stock will be the factor determining margin requirements. Risk rating for stocks ranges from 1-6 (with 6 being the most risky). A significant part of the risk depends on the market capitalization, liquidity, volatility, country of incorporation, industry, and M&A Activity of the underlying instrument.
Margin and collateral changes can be found:
- Main menu > Other > Margin and Collateral Changes.
If you are holding a position that has scheduled trading condition changes, you will see the following sign near your Cash value.
If you click on this sign, you will see Margin monitor, which will show the simulated impact that scheduled trading condition changes will have on your margin utilization on the day the changes come into effect.
You can always check in advance whether a particular instrument will soon go through trading condition changes under Trading Conditions > Instrument.
