Things that people who easily lose money in contracts like to do
1: Like to predict the market and price points
2: Do not watch the market
3: Like to leave orders and sleep, dreaming of waking up rich.
4: Like to leave orders while playing games, and realize they are stuck after finishing the game.
5: After making a profit, they dream of greater profits; after losing money, they panic and run away, only to find that most of their orders were stopped out.
If you can't monitor the market for more than 12 hours a day, it's advised not to trade contracts. If you have more money than you can spend, that's another matter.
