            //_staticCacheManager.Remove(cacheKey);

            //var prefix = _cacheKeyService.PrepareKeyPrefix(NopCatalogDefaults.ProductPricePrefixCacheKey);
            //_staticCacheManager.RemoveByPrefix(prefix);
            _staticCacheManager.RemoveByPrefix("Nop.totals.productprice-");

So i Edit the price via SQL Studio after that i need to run this task to get edited price on product page.

try Settings > Catalog Settings > disable "Cache product prices"

What about In the program you call                
_cacheManager.Clear();
which is the same function as on the Dashoard
