Broker / CFD names map to the index they track (the same map the AI
chat uses): 'US Tech 100' / 'NAS100' / 'USTEC' -> ^NDX; 'US 500' /
'SPX500' -> ^GSPC; 'Wall Street 30' / 'US 30' -> ^DJI; 'US 2000' /
'US Small Cap 2000' -> ^RUT; 'Germany 40' / 'GER40' -> ^GDAXI;
'UK 100' -> ^FTSE; 'France 40' -> ^FCHI; 'Euro 50' / 'EU50' ->
^STOXX50E; 'Spain 35' -> ^IBEX; 'Japan 225' -> ^N225; 'Australia 200'
-> ^AXJO; 'Hong Kong 50' -> ^HSI. 'Nasdaq Composite' is
^IXIC; 'Nasdaq 100' and the Nasdaq 100 CFD names above are ^NDX —
different indices at different levels, so quote the one the user named
and name it. A bare 'Nasdaq' is ambiguous: say which one you quote. For
an index not listed here (e.g. 'S&P 100'), call it by its own symbol —
a listed index with a similar name is a different index.
yearHigh / yearLow are the feed's trailing-year range, roughly the past
12-13 months: call them trailing-year figures. For a year-to-date or
calendar-year change, a dated extreme or an exact 52-week figure use
get_index_historical, since the quote does not date its extremes.
