📥 Installation

Prerequisites

You'll need Git and Node.js v22.12 or newer installed.

Linux Users

Install Git:

# Ubuntu/Debian
sudo apt-get update
sudo apt-get install git

# Arch/Manjaro
sudo pacman -S git

# Fedora/RHEL
sudo dnf install git

Most distro repos ship an outdated nodejs package, so install Node from nodejs.org.

# e.g. via nvm (from https://nodejs.org/en/download)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.6/install.sh | bash
\. "$HOME/.nvm/nvm.sh"
nvm install 24

Verify both installations:

node --version && npm --version && git --version

macOS Users

Use Homebrew to install Node.js and Git:

# Install Homebrew if not already installed
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node.js and Git
brew install node git

Windows Users

1. Install Git from git-scm.com (accept defaults, restart after)
2. Install Node.js LTS from nodejs.org (accept defaults, restart after)
3. Verify installation in Command Prompt:

   node --version && npm --version && git --version

   All three should display version numbers.

Install DEXBot2 from npm (recommended)

npm i -g dexbot

Install DEXBot2 from source (developers)

git clone https://github.com/froooze/DEXBot2.git && cd DEXBot2
npm install
npm link

Where your data lives

Both installs use the same CLI and store all user state — keys, bots.json, logs — in ~/.config/dexbot2/profiles (Windows: %USERPROFILE%\.config\dexbot2\profiles). State lives outside the repo/package tree, so it survives reinstalls and npm update -g. A source checkout that already contains a populated profiles/ directory keeps using it. Override the location with DEXBOT_PROFILE_ROOT (see the developer guide).

🔧 Configuration

Create Your Bot

1. Set up your master password and import your BitShares active key (WIF):

   dexbot key

2. Create a bot through the interactive prompts:

   dexbot bot

   This stores your configuration in bots.json in the profiles directory. The generated defaults are a good starting point — the next step walks through the few options worth tuning.

Recommended Bot Setup

Keep the default settings first, and tune these:

1. Tune targetSpreadPercent — controls profit room per completed cycle: profit ≈ spread - increment - fees. A wider spread targets more profit per cycle but trades less often.

2. Tune incrementPercent — controls order steps and order size. Smaller increments create more grid levels and smaller orders; larger increments create fewer levels and larger orders. Smaller increments cycle faster — higher profits, but more fees.

3. Tune weightDistribution (optional) — per-side sizing control. Higher weight = more funds in orders near the market price; lower weight = funds shifted toward the grid edge. Range -1 (super-valley) to 2 (super-mountain); the default { "sell": 1.0, "buy": 1.0 } suits most setups.

4. Set gridPrice to "ama" — so the market adapter can center the grid on AMA. Pick a specific preset if desired: "ama1" is the fastest, "ama4" the slowest, and "ama" uses the pair's default preset.

5. Generate the market-adapter whitelist:

   dexbot white

   This writes market_adapter_whitelist.json in the profiles directory. New AMA bots get AMA live writes only; dynamic weights and range scaling are disabled by default. Use dexbot white --dynamic-weight or dexbot white --asymmetric-bounds to opt newly generated entries into those features; existing entries are preserved. To overwrite an existing bot, include --bot <botKey> with the desired flags.

6. Start DEXBot2 with dexbot start.

7. Tune minPrice / maxPrice around the market's volatility range. Once AMA is active, tighten them around the maximum expected market volatility instead of using an unnecessarily wide range.

Bot Options Reference

Configuration options from dexbot bot, stored in bots.json in the profiles directory:

Prefer relative values — use dynamic price sources where available: "pool" (liquidity-pool price) or "book" (order-book mid) for startPrice, "ama" for gridPrice, "2x"-style multipliers for minPrice / maxPrice, and "100%"-style percentages for funds (botFunds). Relative values rescale automatically as the market moves; fixed numbers do not. The bot editor highlights these inputs live: green = relative/dynamic (recommended), red = fixed absolute value.

| Parameter | Type | Description | | :--- | :--- | :--- | | assetA | string | Base asset | | assetB | string | Quote asset | | name | string | Friendly name for logging and CLI selection | | active | boolean | false to keep config without running | | dryRun | boolean | Simulate orders without broadcasting | | preferredAccount | string | BitShares account name for trading | | startPrice | num | str | Initial price and adapter source. Default "pool" uses the liquidity-pool price; "book" uses the live order book mid price (best bid/ask); a number uses a fixed anchor. | | poolRef | string | null | Optional pinned pool ID for startPrice: "pool". Overrides pool discovery with a direct fetch (e.g. "1.19.48" or "48"). Useful when the trading pair has no native pool. Default null. | | minPrice | num | str | Lower bound. Default "2x" means gridPrice / 2 when AMA is active, otherwise startPrice / 2. | | maxPrice | num | str | Upper bound. Default "2x" means gridPrice * 2 when AMA is active, otherwise startPrice * 2. | | gridPrice | num | str | null | Grid reference. Use "ama" for the recommended AMA center ("ama" picks the pair's default preset; "ama1"–"ama4" pin fastest to slowest); null falls back to startPrice; numeric values use that fixed value. | | incrementPercent | number | Geometric step between orders. Default 0.5 = 0.5%. | | targetSpreadPercent | number | Width of the empty spread zone between buy and sell orders. Default 2 = 2%. Profit per completed cycle ≈ spread - increment - fees. | | weightDistribution | object | Advanced sizing control per side. Range -1 to 2: -1 = super-valley, 0 = valley, 0.5 = neutral, 1 = mountain (default), 2 = super-mountain. Higher weight = more funds in orders near the market price; lower weight = more funds shifted toward the grid edge. Default { Sell: 1.0, Buy: 1.0 }; leave unchanged for normal setup. | | botFunds | object | Capital: { Sell: "100%", Buy: 100% }. Numbers or percentage strings | | activeOrders | object | Target active orders per side: { S: 20, B: 20 } | | reserveOrders | object | Edge-pinned insurance orders resting live outside the active window, to catch fat fingers: { S: 0, B: 0 } |

General Options (Global)

Global settings via dexbot bot, stored in general.settings.json in the profiles directory:

• Grid Health: Grid Ratio Regeneration % (default 3%), RMS Divergence Threshold % (default 14.3%), AMA Delta Threshold % (default 1%)
• Order Recovery: Partial Dust Threshold % (default 5%), Dust Cancel Delay (default 30s, -1 = off, 0 = instant)
• Node Configuration: Node List (10 default public BitShares nodes), Health Check Interval (default 240 min), Preferred Node (default none)
• Log Level: debug, info, warn, error, critical. Fine-grained category control via LOGGING_CONFIG (see Logging)
• Updater: Active (default OFF), Branch (auto/main/dev/test), Interval (default 1 day), Time (default 00:00)

Constants and Overrides

Defaults in modules/constants.ts are overridable at global, pair, and bot level via general.settings.json, market_profiles.json, and market_adapter_settings.json in the profiles directory. See market_adapter/README.md for examples.

🎯 Zero-Dependency Process Management

dexbot start is the recommended production runtime (global install). Repo-root users can run ./unlock instead. It runs the selected bot set as one monolithic bot process, with the credential daemon and market adapter in separate helper processes. Monolithic start/stop/reload/restart controls apply to the whole runtime, not to individual bots.

dexbot start/stop          # Stop/start the monolithic runtime
dexbot start --dryrun      # Dry-run (no transactions broadcast)
dexbot reload              # Reload the runtime (leaves credential daemon untouched)
dexbot restart             # Restart the runtime (re-unlocks credential daemon)
dexbot delete              # Shut down and clean up

First-run details and common mistakes are covered in the BitShares Onboarding Tutorial.

🛠️ Bot Management

dexbot key                 # Master password/keyring
dexbot bot                 # Interactive bot configurator
dexbot white               # AMA whitelist; dynamic weights and range scaling off by default

dexbot reset {all|<bot>}   # Regenerate grid
dexbot disable {all|<bot>} # Disable bot in config
dexbot enable {all|<bot>}  # Enable bot in config

dexbot stat                # Runtime status (unlock or PM2)
dexbot order [<bot>]       # Analyze order grids
dexbot order --export      # Export as HTML to analysis/charts/
dexbot tv <bot|pool|A/B>   # TradingView 1h chart with AMA overlay (default: 3 months)
dexbot credit [<bot>]      # Live summed MPA + borrowed-credit positions per asset per bot

dexbot update              # Update DEXBot2
dexbot clear               # Clear log files
dexbot default             # Reset settings to defaults

🎯 PM2 Process Management

PM2 is optional — dexbot start is the native solution.

dexbot pm2 [<bot>]                         # Start with PM2
dexbot pm2 reload {all|<bot>}              # Reload managed apps, dexbot-cred untouched
dexbot pm2 restart {all|<bot>|dexbot-cred} # Safe restart
dexbot pm2 stop {all|<bot>}                # Stop (via wrapper)
dexbot pm2 delete {all|<bot>}              # Delete (via wrapper)
pm2 logs [<bot>]                           # Real-time logs

Always use dexbot pm2 restart instead of raw pm2 restart all — the wrapper safely handles the credential daemon. If the credential daemon stops, rerun dexbot pm2.

Repo-root users can use ./pm2 instead of dexbot pm2.

Logs are written to logs/ in the profiles directory in all modes: the monolithic runtime uses dexbot.log / dexbot-error.log, and per-bot output uses <bot>.log / <bot>-error.log.
