KIS Realtime Price Alert Bot: WebSocket Events to Safe Notifications
A safe alerting pattern for turning realtime prices into notifications while keeping order execution and credentials outside public code.
What You Will Build Mentally
Realtime data becomes more useful when it is filtered into clear alerts. This guide keeps the design focused on notification logic, not secret credentials or full private streaming clients.
Safe Reference Pattern
This is original sanitized example code. It is intentionally incomplete around credentials and order placement. Replace placeholders only inside your private environment, never inside public pages, screenshots, or downloadable examples.
def price_alert(symbol, last_price, rules):
rule = rules.get(symbol)
if not rule:
return None
if last_price >= rule["above"]:
return f"{symbol}: price crossed above {rule['above']}"
if last_price <= rule["below"]:
return f"{symbol}: price crossed below {rule['below']}"
return None
rules = {"005930": {"above": 72000, "below": 68000}}
print(price_alert("005930", 72500, rules))Implementation Notes
Design choice
Separate stream handling from alert rules. This keeps reconnect logic and business rules easier to test.
Failure handling
A production alert bot should handle disconnects, stale data, duplicate alerts and market closures.
User value
This is a strong educational article because many developers can connect to data but do not know how to turn it into reliable notifications.

Security and Accuracy Boundary
- No App Key, App Secret, HTS ID, account number, access token, approval key, vault file, executable, or private AlgoSpecial source code is shown here.
- Always verify endpoints, TR IDs, parameters, permissions and rate limits against the current official KIS Developers portal before live use.
- This content is for software education. It is not investment advice, a profit claim, or an instruction to place live trades.

FAQ
Does this show the KIS WebSocket connection?
No. It shows safe alert logic only; connection credentials belong in private code.
Can alerts be sent to Telegram or email?
Yes, but webhook tokens and bot credentials must stay private.
Should every tick create an alert?
No. Add dedupe and cooldown rules in production.
