Definition — When you trade with leverage, you're using borrowed capital, and borrowed capital charges interest. The part most traders miss is when it charges: on StableStock, interest settles at six fixed points a day, intraday session points are waived, and closing before a settlement point costs nothing for the partial period. Understanding the clock is the difference between free intraday leverage and paying for time you didn't need.

When Does Interest Actually Accrue?

Interest on a leveraged position settles every 4 hours — at 00:00, 04:00, 08:00, 12:00, 16:00, and 20:00, in the local time of the market where the stock trades. At each settlement point, the interest due is added to your outstanding loan.

Two rules make this trader-friendly:

• No partial-period charges. Interest is only charged when a settlement point is actually reached. Close or repay before the next point, and the time in between is free.

• Session points are waived on trading days. The settlement points that fall inside the trading session don't charge. A position opened and closed within the session crosses only waived points — total interest: zero.

On non-trading days (weekends and holidays) there is no session window, so all six points accrue. A position held through a weekend carries the full daily financing cost each day.

The Clock at a Glance

What Does a Day of Financing Cost?

Rates vary by stock and market conditions, but at an illustrative level of roughly 15% APR, borrowing 10,000 USDT costs about 4.1 USDT per day held overnight. The position page shows the exact rate for the next settlement and a live countdown, under Position → Interest — always check the live figure rather than assuming.

The practical takeaway from the math: intraday leverage on StableStock is interest-free by design, while multi-day holds are a real, compounding cost that belongs in your trade plan. If your idea needs weeks to play out, the financing drag needs to be part of the expected return — or the position may be better expressed unleveraged.

How Repayment Works

There are two ways to repay the loan:

• Automatic — when you sell to close, the platform repays the loan at the next settlement, in proportion to how much you closed

• Manual — repay any time using the Repay button next to your outstanding loan; interest stops accruing on what you've repaid

Remember that accrued interest is added to your loan at each settlement — which means it also feeds into your LTV. A position held for weeks sees its risk metric creep upward even if the stock price never moves.

On StableStock, the rate for your next settlement and a countdown timer are shown live on every leveraged position — the cost of time is never a surprise.

Takeaway: Leverage interest runs on a fixed clock: six settlement points a day, in-session points waived, nothing charged for partial periods. Intraday round trips are free; overnight holds cost roughly one day's financing per calendar day, weekends included. Check the live rate before you size a multi-day position, and remember accrued interest quietly raises your LTV.
