3 of the past 4 weeks have been profitable for me. One week, I had some kind of mental fart and screwed it up, but I've returned to normal. However, I've been trading only 100 shares at a time. If this week is profitable, I'm thinking about trying 200 shares at a time. What general rules do you guys use for taking up size? What difficulties did you encounter? How long do you wait for consistency before you take up the size? I have a feeling trading with 200 won't be terrible, but I'm cautious about it nonetheless.
