mt5.shutdown() in MetaTrader5 Python: close the link to the terminal

Signature

mt5.shutdown()

What it does

Call shutdown() when your script is done with the terminal. It ends your script's link; the terminal itself keeps running.

After shutdown(), every other function fails until you call initialize() again.

What it returns

• None. There is nothing to check.

Example

import MetaTrader5 as mt5

if not mt5.initialize():
    raise SystemExit(mt5.last_error())
try:
    print(mt5.account_info().balance)
finally:
    mt5.shutdown()   # runs even if the code above raised

Common mistakes

• Put shutdown() in a finally block so a crash in your code still closes the link.
• In a long-running service, do not call initialize() and shutdown() around every request. Open the link once and keep it.

The same with Tickwire on Linux

The package needs a Windows terminal on the same machine. Tickwire runs the terminal for you and gives you a REST API, so the code below runs on Linux, macOS or a server.

There is no link to close on Tickwire. Each request is a plain HTTPS call, and the hosted terminal keeps running between them.
