symbol_info_tick does not ensure that a valid value was obtained. If one has not shown the symbol in the Market Watch window then 'None' is returned for the symbol instead of an exception.

That is the default behavior programmed by MetaQuotes. In order to modify that behavior using pymt5adapter you have to use the context manager and set the raise_on_errors flag.

import pymt5adapter as mta
with mta.connected(raise_on_errors=True):
    s = mta.symbol_info_tick('Not a symbol')
