conversion ratio is set
>summary
shopping cart module working fine, even with currency switcher module currrency switch(frontend) changing prices display correct new price in cart field module. But all product on page somehow displaying only in price that was set in backend in USD only if current currency is USD, in all other cases it's "FREE" (EUR,UAH).
>code dig
digging to file listing_price.php showed that
if price is USD $this->row->prices have correct values in all other cases it's NULL without another code to recalculate price...

thank you, installed update and it works now
