# Trading automation

## Goal

Compose `mp` CLI commands with OS scheduling (cron/launchd) to run unattended trading strategies: dollar-cost averaging, limit orders, and stop losses. The agent generates shell scripts and schedules them — no new tools needed.

## Prerequisites

- Authenticated: `mp user retrieve`
- Funded wallet: `mp token balance list --wallet <name> --chain <chain>`
- `mp` binary on PATH: `which mp` (note the full path for scheduled scripts)
- `jq` installed: `which jq`

## Shell script pattern

Every strategy uses the same base pattern. Scripts live in `~/.config/moonpay/scripts/` and log to `~/.config/moonpay/logs/trading.log`.

```bash
#!/bin/bash
set -euo pipefail

MP="$(which mp)"  # absolute path for cron/launchd
LOG="$HOME/.config/moonpay/logs/trading.log"
mkdir -p "$(dirname "$LOG")"

log() { echo "[$(date -u +%Y-%m-%dT%H:%M:%SZ)] $*" >> "$LOG"; }

# --- Config (agent fills these in) ---
WALLET="main"
CHAIN="solana"
FROM_TOKEN="EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"  # USDC
TO_TOKEN="So11111111111111111111111111111111111111111"         # SOL
AMOUNT=5

# --- Execute ---
log "SWAP: $AMOUNT $FROM_TOKEN -> $TO_TOKEN on $CHAIN"
RESULT=$("$MP" --json token swap \
  --wallet "$WALLET" --chain "$CHAIN" \
  --from-token "$FROM_TOKEN" --from-amount "$AMOUNT" \
  --to-token "$TO_TOKEN" 2>&1) || {
  log "FAILED: $RESULT"
  exit 1
}
log "OK: $RESULT"
```

Key points:
- `mp --json` outputs single-line JSON, ideal for `jq` parsing
- Use `$(which mp)` and store as `MP` — cron/launchd have minimal PATH
- Wallet names only in scripts — `mp` handles keychain decryption at runtime
- If the user gives token names/symbols, resolve to addresses first with `mp token search`

## DCA (Dollar-Cost Averaging)

"Buy $5 of SOL every day at 9am"

### Script: `~/.config/moonpay/scripts/dca-sol.sh`

Use the base pattern above with the user's token, amount, wallet, and chain.

### Schedule with cron (Linux)

```bash
# Buy $5 of SOL daily at 9am UTC — moonpay:dca-sol
0 9 * * * ~/.config/moonpay/scripts/dca-sol.sh
```

Add with: `(crontab -l 2>/dev/null; echo '0 9 * * * ~/.config/moonpay/scripts/dca-sol.sh # moonpay:dca-sol') | crontab -`

Common intervals:
- Every hour: `0 * * * *`
- Every 4 hours: `0 */4 * * *`
- Daily at 9am: `0 9 * * *`
- Weekly Monday 9am: `0 9 * * 1`

### Schedule with launchd (macOS)

Write a plist to `~/Library/LaunchAgents/com.moonpay.dca-sol.plist`:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.moonpay.dca-sol</string>
  <key>ProgramArguments</key>
  <array>
    <string>/bin/bash</string>
    <string>/Users/USERNAME/.config/moonpay/scripts/dca-sol.sh</string>
  </array>
  <key>StartCalendarInterval</key>
  <dict>
    <key>Hour</key>
    <integer>9</integer>
    <key>Minute</key>
    <integer>0</integer>
  </dict>
  <key>StandardErrorPath</key>
  <string>/Users/USERNAME/.config/moonpay/logs/dca-sol.err</string>
</dict>
</plist>
```

Load with: `launchctl load ~/Library/LaunchAgents/com.moonpay.dca-sol.plist`

**Important:** Tilde (`~`) does NOT expand in plist files. Always use the full path (e.g., `/Users/USERNAME/...`). Get it with `echo $HOME`.

## Limit order

"Buy SOL when price drops below $80"

### Script: `~/.config/moonpay/scripts/limit-buy-sol.sh`

```bash
#!/bin/bash
set -euo pipefail
