Let's clarify first, let's make things clear. Most of what you're doing today is short-term long positions, right? Your main idea is to short the rebound, right?

1865/1885/1905 and so on... Wait a moment, don't wait until the rebound reaches 2150 and these guys start arguing that you successfully bottomed out. Are you reducing your position now at 1865? After reducing, are you still short?
When you talk about shorting on a rebound, which resistance level are you shorting? Don't wait until the market moves and then come back to me with excuses!
