Place a short order at 3250, and for the rest, as long as you can top up the margin, you don't need to worry about it. I just checked, the highest point was 3231, there was a spike, not sure if it can go a little higher.

Once the orders are placed and all the margin is topped up, you don't need to worry about it. I'm using cross margin, so the default is to use my assets as margin. If you're using isolated margin, remember to fully top up the margin for each position.

For example, if you have 100U,
You enter once at 3090 with 10U, then place another at 3250 with 20U, and the remaining 70U can all be used as margin.

If you keep staring at the K-line and your position, it's easy to lose your nerve. I'll probably just check again on the day the Fed cuts rates.
