Most trading companies are represented at the New York Stock Exchange. Contact them for internship and employment, but it's a contracting industry and very competitive.

Your college counselor would be your best bet to start out.

I would keep the part about "trading stocks" under your hat, unless you have phenomenal track record trading huge amounts of money and can prove it with statements. Everybody thinks they're a "trader" already, but are usually clueless.

Also check out the Toronto Stock Exchange. The Toronto Stock Exchange was formerly the TSE, but now goes by TSX. Also the TMX Group was formally the TSX Group.

The largest stock exchange in Canada. The Toronto Stock Exchange (TSX) was established in 1852 and formally incorporated in 1878. The exchange is located on Bay Street in Toronto and is owned and operated by the TMX Group.

Also one in Montreal, depending on where you are.
