# WickBot — Linux/Docker deployment via Wine
#
# This runs a real Windows MT5 terminal inside Wine, a small RPyC server
# next to it (mt5linux), and the bot itself (Linux-native Python) talking
# to that server over localhost. See mt5_connector.py for the client side.
#
# IMPORTANT — read before deploying:
#   - This is inherently more fragile than running WickBot natively on
#     Windows. Wine + a GUI trading terminal in a headless container is a
#     known-workable but occasionally finicky combination.
#   - The MT5 terminal needs to be logged in at least once. Headless
#     containers have no screen to click through a login dialog, so the
#     first login is easiest done via the VNC port exposed below —
#     connect a VNC viewer to it once, log in, and (if your storage is
#     persistent) it should stay logged in on restarts. On Hugging Face
#     Spaces specifically, storage may not persist across a full rebuild,
#     so you may need to re-login after those.
#   - Long-running background processes on free-tier hosting can be
#     paused/killed on inactivity or resource limits — check your
#     platform's policy for always-on containers before relying on this
#     for anything beyond training/paper trading.
#
# Build:   docker build -t wickbot -f docker/Dockerfile .
# Run:     docker run -p 5900:5900 --env-file .env wickbot
# Then connect a VNC client to <host>:5900 to log into MT5 the first time.
