In certain scenarios, an instrument may not be tradable at all or may only be traded to reduce or close an existing position.
The warning triangle highlights such instruments across all modules (search, product page, screener, watchlist, trade ticket, position, chart, etc.) to prevent you from encountering order an rejection.
A detailed explanation of why a specific instrument is not tradable is also available by simply hovering over or clicking on the warning.
Can I hide these instruments that are not tradable?
You can choose to make these instruments not visible on the platform by going to the main menu > Platform settings > Platform & Trading > Show non-tradable instruments in platform
Turning the toggle OFF essentially hides instruments that have a warning in the search and the screener.
Be aware that:
Switching off the non-tradable instruments does not hide an instrument previously added to a watchlist or an existing position. Continuous futures or stock index instruments are also not impacted by this flag.
