What is allowed
Holding any coin, any size inside the per-coin limit, for as long as you like: through UTC midnight, through a weekend, through a week away. Solana markets do not close, and there is no rule here that forces you flat at a set hour. Up to 5 coins can be held at once, each within 20%, 15% or 10% of the account by size.
What keeps running while you sleep
The check. Your equity, meaning SOL held plus every open coin at its live price, is compared with the loss line every 30 seconds, whether or not you are online. A coin that falls hard at 4am can take equity to the line and close the account before you wake. There is no margin call and nothing is owed, but there is also no one to ask you first. The rule that matters overnight is the only loss rule there is.
The dead-coin rule
One more overnight risk is specific to memecoins. If BLIX is pricing your other coins but has not priced one you hold for 30 minutes, that coin is treated as dead, typically because its pool was pulled or it rugged, and it counts as worth nothing. A coin you would have sold at the first sign of trouble while awake is the coin this rule finds while you are not.
What midnight UTC does
At 00:00 UTC the day rolls, and three things that depend on the day are settled. The loss line is recalculated from your closed balance, which counts open coins at what you paid for them, so an unrealised gain held over midnight does not lift the line. A day's realised profit is fixed, and a coin you are still holding has realised nothing. So a position bought at 23:00 and sold at 01:00 puts its profit into the new day, which matters for a counted day and for the 60% rule.
Before you step away
- Ask whether you would hold this coin with your own SOL and no way to sell for eight hours. That is the position you are in.
- Look at the distance between equity and the line, not at the balance. A held coin can cover that distance in one candle.
- A request for a payout needs every coin sold, so a held coin is also a payout you cannot request until morning.
- Being away does not fail anything by itself. Time off has no rule against it; only a held coin can cost you while you are gone.
Questions people ask
Is weekend holding allowed?
Yes. There is no weekend rule, and Solana trades through the weekend like any other day.
Does the loss line move at midnight because of an open gain?
No. It recalculates from your closed balance, which counts open coins at cost, so only sold profit can lift it.
Will I be warned before my account fails overnight?
Do not count on it. The check runs every 30 seconds and acts on what it finds, so the distance to the line when you log off is the protection you have.
