# Transaction Settings
> Slippage, priority fees and MEV protection — with Chill / Rush / Ape presets that track live market values automatically.
Three dials control how your trades land: slippage, priority fee, and MEV protection. Defaults work for most trades; understanding them is what separates configured edge from donated edge.
Open them from the trade panel (gear icon) — set globally, per token, or save combinations as presets.
## Slippage
The maximum price movement you accept between clicking and filling.
* **Established tokens, deep liquidity:** low slippage (1–5%) is fine.
* **Fresh trenches tokens:** 20–30% is realistic — shallow pools move fast. Trades with tight slippage on volatile tokens simply revert.
* **Never set it high "just to make it fill" on size.** High slippage on a visible transaction is an invitation to be sandwiched. Understand the trade-off: [Slippage, Priority Fees & MEV](/learn/slippage-priority-fees-mev).
## Priority fee
What you pay the network to process your transaction ahead of others. On Solana this is the difference between landing in the next block and landing after the move is over.
* Default: dynamic, matched to current network conditions. {/* TODO(team): confirm default priority fee behavior and ranges */}
* Raise it when the network is hot (major launch, meta day) and your fills are lagging.
* This fee goes to the network, not to Trady.
## MEV protection
Sandwich bots watch pending transactions, buy in front of yours, and sell into your fill — you buy higher, they pocket the difference. MEV protection routes your transaction privately so bots can't see it before it lands.
* **Keep it on for anything with size.** The cost of protection is a marginally slower land; the cost of a sandwich is real money.
* Trades routed privately can take slightly longer to confirm — that's the mechanism working, not a bug.
## Presets
Four presets, one click to switch. Three of them are **fully automatic** — they track current market averages in real time, so they stay correct as network conditions change:
| Preset | Settings | When |
| ------------- | ------------------------------ | --------------------------------------------------------- |
| **Chill** 😌 | Current market averages, as-is | Normal conditions, no rush |
| **Rush** 🏃 | Market averages × 1.5 | Competitive moments — you want to land ahead of the crowd |
| **Ape** 🦍 | Market averages × 2 | Hot launches and meta frenzies — priority over price |
| **Custom** 🛠 | Fully manual | You know exactly what this trade needs |
The automatic presets solve the real problem with manual settings: the "right" priority fee at 14:00 is wrong by 14:05. Chill/Rush/Ape recalculate from live market values, so "aggressive" always means *aggressive relative to right now*.
**Custom** hands you every dial — slippage, priority fee, MEV mode — for trades where you've decided the trade-offs yourself.
Presets apply wherever you execute — including the [Instant Trade window and the Quick Buy widget](/trading/instant-trade-quick-buy-sell), where they're configured directly in place.
## Mini-FAQ
**What should a beginner change?**
Nothing — stay on **Chill**. Move to Rush/Ape when you understand *why* a specific trade needs to outbid the market, and to Custom when you've stopped needing this page.
**Why did my trade fail with "slippage exceeded"?**
Price moved past your cap before the fill. Retry with higher slippage or smaller size — and ask yourself whether chasing a candle that outran your slippage is an entry or a FOMO tax. See [Failed Transactions](/troubleshooting/failed-transactions).
**Does Trady profit from priority fees or MEV settings?**
No. Priority fees go to the network. Trady's only trading revenue is the [trading fee](/fees-rewards/fees).
