i want to know if i can cancel an auction

first of all, i would like to apologize to the staff because i have been pm-ing like 4 of them about this issue, in my defense, i though that i would solve my issue faster that way and with less problems for the staff than making a thread for it.

i have opened a thread in trade where i am selling a pokemon, the auction is going to last another 2 days, and there is one player winning it a the moment that has offered me a private offer for that pokemon. i set an insta price for the pokemon, but the insta is too high and i would actually like to accept his private offering as the insta, but i dont know if i can do that now that i have started the auction. is it ok if i cancel the auction and just sell the pokemon to that player afterwards?

also, i want to start sinnoh but i cant becuase i need the auction to end first, since if i start sinnoh is going to lock my pokemon until i win 8 badges again i suppose

thanks and sorry again for the private spam.
