I provided a couple targets for both directions.
Small green arrows are 1.618 extensions of the big green arrows.
They nicely land into existing key levels.
I prefer the upside as it would be a good point (in the context of the 2. auction) to break the long-term resistance diagonal (blue dashed line) and go into a new uptrend with new highs above 1k :]
For stop placement, you can use a significant price rejection area, or a low of a congestion area.
Risk is 2.49%, so you can use 2x leverage and risk your whole account value two times for a 5% total risk which is relatively acceptable. (20 trades and game over)
