What is equities sales and trading

For example, when a customers trade is winning, the countdown to expiration is extended arbitrarily until the trade becomes a loss.

In this example, an investor could expect -- on average -- to lose money. If you cannot verify that they are registered, dont trade with them, dont give them any money, and dont share your personal information with them.
