I'm executing market orders through arca, sometimes I get charged 0.25 sometimes 0.30 sometimes 0.35 for 100 shares, what causes this changes? Plus the sec fee sometimes is charged sometimes not
It depends on what your doing, if the order is routed out, etc. Here's a link to their website. As for the SEC fees, they're only charged on the sale of stock, not the purchase. http://www.nyse.com/productservices/nysearcaequities/1157018931977.html
