SKILL.md

kraken-alert-patterns

Use this skill for:

monitoring price levels and triggering alerts
detecting spread widening, volume spikes, and volatility shifts
watching account state changes (fills, balance drops)
building notification-driven agent workflows

Price Alert (Polling)

Check price at intervals and compare against thresholds:

bash

PRICE=$(kraken ticker BTCUSD -o json 2>/dev/null | jq -r '.[].last_price')
# Agent compares $PRICE to upper/lower thresholds
# If breached, notify the user

Price Alert (Streaming)

More efficient for continuous monitoring. The agent reads the stream and fires when conditions are met:

bash

kraken ws ticker BTC/USD -o json 2>/dev/null | while read -r line; do
  LAST=$(echo "$line" | jq -r '.data[0].last // empty')
  [ -z "$LAST" ] && continue
  # Compare against thresholds, break or notify on breach
done

Spread Alert

Detect when the bid-ask spread widens beyond a threshold (liquidity warning):

bash

kraken ws ticker BTC/USD --event-trigger bbo -o json 2>/dev/null | while read -r line; do
  ASK=$(echo "$line" | jq -r '.data[0].ask // empty')
  BID=$(echo "$line" | jq -r '.data[0].bid // empty')
  [ -z "$ASK" ] || [ -z "$BID" ] && continue
  SPREAD=$(echo "$ASK - $BID" | bc)
  # Alert if spread exceeds threshold
done

Volume Spike Detection

Compare current 24h volume against a baseline:

bash

kraken ticker BTCUSD -o json 2>/dev/null | jq -r '.[].volume_24h'
# Agent compares to historical average
# Alert if volume > 2x baseline

Volatility Alert (OHLC-Based)

Read recent candles and compute range or standard deviation:

bash

kraken ohlc BTCUSD --interval 60 -o json 2>/dev/null
# Agent calculates high-low range per candle
# Alert if range exceeds threshold

Balance Change Alert

Monitor for unexpected balance changes:

bash

INITIAL=$(kraken balance -o json 2>/dev/null | jq -r '.USD // "0"')
# On each check:
CURRENT=$(kraken balance -o json 2>/dev/null | jq -r '.USD // "0"')
# Alert if |CURRENT - INITIAL| exceeds threshold

Streaming alternative:

bash

kraken ws balances -o json 2>/dev/null
# Each line is a balance update event

Fill Notification

Alert on trade executions:

bash

kraken ws executions -o json 2>/dev/null | while read -r line; do
  TYPE=$(echo "$line" | jq -r '.data[0].exec_type // empty')
  [ "$TYPE" = "trade" ] && echo "Fill: $line"
done

Futures Alerts

Monitor futures positions for margin or P&L thresholds:

bash

kraken futures positions -o json 2>/dev/null
# Agent checks unrealized P&L against stop-loss threshold

Stream futures balance changes:

bash

kraken futures ws balances -o json 2>/dev/null

Futures notifications (margin calls, liquidation warnings):

bash

kraken futures ws notifications -o json 2>/dev/null

Multi-Pair Alert

Watch several pairs and alert on the first one that hits a condition:

bash

kraken ws ticker BTC/USD ETH/USD SOL/USD -o json 2>/dev/null | while read -r line; do
  PAIR=$(echo "$line" | jq -r '.data[0].symbol // empty')
  LAST=$(echo "$line" | jq -r '.data[0].last // empty')
  [ -z "$PAIR" ] || [ -z "$LAST" ] && continue
  # Check pair-specific thresholds
done

Notification Delivery

The CLI outputs alerts to stdout. The agent is responsible for delivering notifications through its own channels (Slack, email, push notification, or presenting to the user in chat).

Pattern Summary

Condition	Method	Command
Price crosses level	Stream	`ws ticker <PAIR>`
Spread widens	Stream	`ws ticker <PAIR> --event-trigger bbo`
Volume spike	Poll	`ticker <PAIR>`
Balance change	Stream	`ws balances`
Trade fill	Stream	`ws executions`
Futures margin	Stream	`futures ws balances`
Futures notification	Stream	`futures ws notifications`

Hard Rules

Alerts are informational; they do not execute trades automatically.
Prefer streaming over high-frequency polling to reduce API load.
Close streams when monitoring is no longer needed.
If you hit a mismatch between what you are trying to do and the CLI's interface or responses — including a mismatch between this skill and the installed CLI version's contract — feel free to submit feedback with kraken feedback.
