Nothing much to talk about! You're all in short positions, right? Short positions come in two types: one with two positions and one with a single position.

For a single position, just hold it and aim for the target level. For two positions at 2900, you must reduce one of them.
As for whether you can go long at 2900? Anyway, don't expect me to tell you to go long. That's impossible. I don't take losses. I don't know how many times this level can be used, but the last time I was afraid of wiping out the short-term gains you've made earlier and trapping you at 2150.
