"""
actions.py — Action handler for dry/confirm/live modes.
========================================================
Every action the bot takes (place order, cancel order, update TP)
goes through this handler. The mode controls what actually happens.

MODES:
------
dryrun  → Logs what it would do. Returns None. No API calls made.
confirm → Prints the action, waits for y/n input. Only proceeds on 'y'.
live    → Executes immediately, no prompts.

All three modes log the action clearly so you can audit what happened.

WHY THIS MATTERS:
-----------------
Before trusting the bot with live orders, run in dryrun and confirm modes.
Watch the logs for several days. Only switch to live when you're confident
the logic is correct and the orders it wants to place match your expectations.
