Fees and funding
Three costs affect a grid's net result: the builder fee GRIDer charges, the exchange's own trading fee, and funding on perpetual positions. This page explains all three, and how GRIDer accounts for them so the PNL you see is honest.
The builder fee
GRIDer charges a builder fee of 0.008% per trade. This is the platform's revenue, approved once during account setup via a signature on the exchange. You can't run a grid without approving it — the bot needs it to operate.
- 0.008% means $0.80 per $10,000 traded. Normal grid spacing is usually around 1% or more, so the fee is a small slice of each completed trade.
- On perps, the fee applies to both buys and sells.
- On spot, it depends on the DEX — on Hyperliquid, for example, the fee applies to sells only, so a spot grid pays roughly half the fee of an equivalent perp.
Beyond the builder fee, GRIDer adds no subscription, no setup cost and no withdrawal fee.
The exchange's own trading fees
Separate from GRIDer's builder fee, the perpetuals DEX charges its own standard trading fee on every order — a maker/taker fee paid to the venue, exactly as for any trade you place yourself. GRIDer neither sets nor receives it.
- It applies on both perpetual and spot markets, on every fill the grid makes.
- Maker and taker rates differ, and most venues lower them as your trading volume grows. Check the exchange's published fee schedule for the current numbers — on Hyperliquid, see Hyperliquid's fee documentation.
- For normal grid spacing, the exchange fee is also a small cost relative to the distance between levels.
Why fee transparency matters for grids. Fees are usually small compared with typical grid spacing, but they are still part of the real result. GRIDer shows them separately so your PNL reflects what actually happened, and so unusually tight grids can be reviewed with the backtesting tool.
Funding (perpetuals only)
On perpetual markets, traders pay or receive funding roughly every hour. It's a periodic payment between longs and shorts that keeps the perp price tethered to the spot price.
- If you're long and funding is positive, you pay; if it's negative, you receive. For a short, it's the reverse.
- Funding can be a tailwind or a headwind depending on direction and market conditions. On some markets, a SHORT grid earns funding while it trades; on others it costs.
- Spot grids have no funding.
How GRIDer handles funding
GRIDer treats funding as a real part of your result, everywhere you see PNL:
Grid PNL = position PnL + closed PnL − fees + funding
- Funding is pulled live from the exchange for your grid's window — it is never guessed or cached.
- The sign matches your perspective: funding received is positive, funding paid is negative.
- The same formula is used in the live panel, in the share card, and in the record saved when a grid closes — so the number is consistent from screen to history.
You can see the breakdown behind the combined number via the ℹ️ icon next to Grid PNL in the trading panel, and a dedicated funding history for coins with an active grid.
Putting it together
For a perpetual grid, your net result is the sum of:
- Closed trade profits — the spread captured on each completed buy/sell pair.
- Open position PnL — the unrealized value of whatever the grid currently holds.
- − Fees — the builder fee plus the exchange's own trading fee on each trade.
- ± Funding — accrued over the life of the grid.
For a spot grid, drop funding and remember the builder fee is sell‑side only on some DEXs like Hyperliquid.
