Hi. I've made an offer with Comsec for $500 worth of shares last week when the market went down but they it didn't go thru and it is still sitting there with a few offers above it. For the life of me I can't figure out how to change it or edit it or cancel it. I would like to make another higher offer but how do I finish the offer I've already made? Could some nice person please post what do I do here. Thankyou.
