At this juncture , I think not many traders would want to trade this two products , the Russian index or the USDRUB currency.
The stock market has tanked and been ordered to close its operation and investors , especially those who owned Russian stocks through ETFs or other products are either busy selling off their shares or considering a total loss.
Same thing for the Ruble currency. It has depreciated so much agains the USD and until we can have some certainty about the war, this situation will only worsen , perhaps to the delights of the algo traders .
Stay safe !
