# 2026-04-04: Research-first advanced settings and execution defaults

> Guided execution presets, simplified slippage controls, and workspace-level backtest defaults.

This update makes it easier to configure backtest execution settings and
introduces workspace-level defaults so your team can start research from a
consistent baseline.

## What changed

### Guided advanced settings

The QuickRun panel now organizes execution controls into clear groups:

* **Execution Preset** — pick a starting point
* **Costs & Friction** — fees and slippage
* **Portfolio Guardrails** — risk limits
* **Expert Settings** — fine-grained control for advanced users

This makes it easy to launch a backtest quickly while keeping detailed options
accessible when you need them.

### Execution presets

Three presets are now available when configuring a backtest:

| Preset              | What it does                                                                                                                      |
| ------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
| **Workspace**       | Uses your saved workspace defaults. New workspaces start with zero friction.                                                      |
| **Market Baseline** | Applies realistic crypto spot assumptions: taker routing, `6 bps / 10 bps` fees, and `ATR x0.25` slippage (capped to `2–20 bps`). |
| **Stress Test**     | Same fee structure with harsher slippage: `ATR x0.40` (capped to `4–30 bps`).                                                     |

### Simplified slippage controls

You now configure slippage using three straightforward options:

* **None** — no slippage applied
* **Fixed** — a constant amount in basis points or ticks
* **Volatility Scaled** — scales with market volatility using ATR

Fill logic (how simulated orders execute) is handled automatically by Traseq
and stays consistent across all backtests.

### Workspace backtest defaults

Workspace settings now include a dedicated **Backtest Defaults** section that
prefills every new backtest with your preferred symbol, timeframe, date range,
balance, fees, and slippage. This keeps your team aligned without needing to
reconfigure each run manually.

### Terminology update

"Impact" has been renamed to **Slippage** throughout the product for clarity
and consistency.

## Why this matters

These changes make it simpler to get started with realistic execution
assumptions. Most researchers can pick a preset and go, while advanced users
still have full control over every parameter.
