# Why is slippage higher on some Stock Tokens outside US market hours?

Quotes on Arcus come from market makers, and their pricing reflects how easily they can hedge the underlying stock at that moment. During US trading hours, most names quote with tight spreads. Outside those hours - overnight, weekends, and US market holidays - liquidity on certain markets is lower, so spreads widen and larger orders can see meaningful price impact.

This affects some tokens more than others. Heavily traded names tend to stay liquid around the clock. Less-traded names are quoted more thinly off-hours, and sell quotes in particular may widen, since a market maker buying your tokens can't hedge the position until the underlying market reopens. In quiet markets a thin name may briefly show a very wide quote, or none at all.

## A few things that help:

* The estimated quote is shown before you confirm, and execution never settles worse than your slippage tolerance - so review the quote and price impact before signing, especially off-hours.
* For less-traded names, smaller trade sizes typically receive better pricing than one large order.
* Pricing on thin names generally tightens when US markets reopen; if a quote looks unusually wide, checking again during US trading hours will usually show a better price.
