Q:You are in America early Friday morning and you call your broker in Eretz Yisrael where it is an hour b/4 shabbos to make a trade when he finishes the trade it will be shabbos already can you do this what about an Ebay bid ending on shabbos or keeping your website open on shabbos

A:In the case of your stoke broker there is a problem of the non jew doing something for you(mase milacha) there is also a problem of being kone something on shabbos. Being kone on shabbos would make the Ebay biding ending on shabbos also a problem. Always ask a shila by your website being open on shabbos it could be a problem especially if it is pashut that it is jewish owned maris ayin would be a problem
