Slippage
Slippage is the difference between the expected price of a trade and the price at which it actually executes. If market movement exceeds your slippage tolerance, APM automatically cancels the trade to avoid filling at a bad price. Setting slippage correctly is key to both execution success and cost control.
📐Recommended range
Range: 1%–100%
Low slippage (1–2%): For highly liquid, stable large-cap tokens
Medium to high slippage (5–15% or higher): For volatile or early-stage meme tokens with thin liquidity to improve fill rates
⚙️ Default value and best practices
Default setting
APM defaults to 10%, which suits most meme coins and medium-volatility markets. It balances success rate and safety.
How to adjust
High volatility / low liquidity → raise slippage (suggest 15–25%) Low volatility / deep liquidity → lower slippage (suggest 1–5%)
Troubleshooting
If you get a “slippage too low” failure, increase slippage by a few percentage points and retry.
Pump.fun rule
Pump.fun uses one-sided slippage. Leave extra SOL when buying (for 20% slippage, a 1 SOL buy needs at least 1.2 SOL). APM will auto-reduce slippage if your balance is too low so the transaction can still be sent.
Anti-MEV
For large trades (>1 SOL), do not set slippage excessively high. Even with MEV protection enabled, extreme slippage can invite sandwich attacks. Reasonable slippage is your first and best defence.
