In WunderTrading we define strategy as a complete plan of actions that should be predetermined by the trader before each order. That is why our terminal has advanced order types, which allow setting the entry and exit points in each strategy.
Long Position is created when a Тrader buys (Enters Long) security with the expectation that it will rise in value to sell (Exit Long) it later.
Short Position is created when a Тrader sells (Enter Short) security first with the intention of repurchasing it at a lower price, i.e. to buy it back (Exit Short).
