Hi I did put a BUY order on a London Stocks Exchange for NLB.GDR. My order was buy 2700 shares price 12.90 however, this morning only 9 shares were executed, that is around 116eur, while the minimum commission is 4eur. So now I'm thinking what will happen: 1) if I change order to 13.00 to buy 130 more shares that are available, will this be billed as two 4 eur commissions? 2) what if my order stays open for several days, would every day of trading 4 eur commission will be billed? OR simply For London stock exchange, if I change order amount, would IB charge me two minimal commissions? What if my order stays open for several days, will IB charge me commission per each trading day?
