What is rolling position?

Aren't contracts only about full position and isolated margin?

I've been watching all afternoon $ETH

The price is still fluctuating around 1792,

But SAR is sometimes 1797, sometimes 1783, sometimes 1760, and there's even one at 1622

—The same coin, the same afternoon,

This indicator swings more than my blood pressure.

RSI jumps from 52 to 64,

MACD shifts from -2 to +6 and then to +47,

It makes me doubt whether I’ve chosen the wrong asset.

The 24-hour low is 1713,

The high is 1848,

Up and down like this,

People with weak hearts really need to keep some quick-acting heart medicine.

Then I saw someone showing off $HYPE ‌making 24%,

Jealousy aside,

But I know if I entered,

That 24% is probably the percentage I’d lose.

Rolling position?

I haven't even figured out what rolling position is,

Can't even handle full or isolated margin well,

Rolling position probably means just rolling the position along,

What if it snowballs halfway and gets out of control?

Anyway, I’ve realized now

—In this market, people who understand don’t talk, and those who talk don’t necessarily understand. Those who understand and talk are mostly just selling stuff. I’m one of those who don’t understand but insist on saying a few words because I’m really anxious.

Where is ETH heading tonight? Who knows. But in the afternoon, I was still watching these lines, we’re all just lovely neighbors in the same leek field.
I just want to ask, what exactly does rolling position mean? Who knows!
