I'd like to have a better understanding of order tickets

• How do I switch my order panel mode?
• I'd like to set my Take Profit and Stop Loss in dollar terms and as a percentage of my account balance
• Why is my order placed with different parameters?
• I'd like to see a simplified order ticket
• Why was my Limit Order executed right after the placement?
• Why is the price of the order execution different from the Close price on the chart?
• Why can’t I place a Stop Order?
• Why was my order canceled?
• Where can I see the expiration time of the order?
• Why is the Time in Force setting not shown in the Order panel?
