Have you ever experienced the following?
1. Pushed the buy button when you want to sell or pushed the sell button when you want to buy.
2. Typed in the wrong price when entering an order.
3. Have the trade move past your stop before you finish placing the order.
4. Hesitate in placing a stop order and have your trade move against you.
5. Try to sell at the peak, but the price already moved back down by the time you finished placing your order.
Why not manage your trade automatically?
