I undestand now.
Operations has confirmed that they’ll change minimum size for SPA35 to 0.10 also on demo accounts so that it reflects live trading conditions.
Should you want to trade it live (0.10 minimum size), you’d need to ask our support team (firstname.lastname@example.org) to enable it for you manually. SPA35 is enabled manually upon request since we have not managed to adapt our risk manager to its timetable yet. Therefore, although you can create a DARWIN from an MT4/MT5 strategy which has traded the IBEX, once the DARWIN has been created, that asset will be disabled on the underlying strategy.
Unfortunately, for the time being, reducing the SPA35 minimum size to microlots is not on the short-term roadmap.
