4. Don't ever quit in the middle of a winning streak. If you manage to win 10 unit keep playing with a goal of winning another 10 units. As long as you keep winning keep setting 10 unit winning goals. However when the tide turns, and you began to loose, quite the streak with your profit. Remember, a small profit is better than no profit!
5. Line movements are tricky, however most of the time very accurate, so under that its moving for a good reason. If the movement is between 0-15 cents I would play it out. If it's between 11-15 cents I would consider the size of the play, how cold/hot you have been running, and how you feel about the situation. But in general, I would play it out in that range as well. If it's over 15 cents I would def. suggest lowering by a half-Unit or Unit, using your own discretion. If its a 5-Unit play and the line has moved 20 cents I would lower it a full unit.
